Settin’ Up A Ftp:

Well, since many of us have always wondered this, here it is. Lon’ and drawn out. Also, before attemptin’ this, realize one thin’; You will have to give up your time, effort, bandwidth, and security to have a quality ftp server.
That bein’ said, here it goes. First of all, find out if your IP (Internet Protocol) is static (not chan’in’) or dynamic (changes everytime you log on). To do this, first consider de fact if you have a dial up mothem. If you do, chances are about 999 999 out of 1 000 000 that your IP is dynamic. To make it static, just go to a place like h*tp://www.myftp.org/ to register for a static ip address.

You’ll den need to get your IP. This can be done by doin’ this:
Goin’ to Start -> Run -> winipcfg or www.ask.com and askin’ ‘What is my IP?’

After doin’ so, you’ll need to download an FTP server client. Personally, I’d recommend G6 FTP Server, Serv-U FTPor Bullitproof v2.15 all three of which are extremely reliable, and de norm of de ftp world.
You can download them on this site: h*tp://www.liaokai.com/softw_en/d_index.htm

First, you’ll have to set up your ftp. For this guide, I will use step-by-step instructions for G6. First, you’ll have to go into ‘Setup -> General’. From here, type in your port # (default is 21). I recommend somethin’ unique, or somethin’ a bit larger (ex: 3069). If you want to, check de number of max users (this sets de amount of simultaneous maximum users on your server at once performin’ actions - The more on at once, de slower de connection and vice versa).

The below options are den chooseable:
-Launch with windows
-Activate FTP Server on Start-up
-Put into tray on startup
-Allow multiple instances
-Show “Loadin’…” status at startup
-Scan drive(s) at startup
-Confirm exit

You can do what you want with dese, as dey are pretty self explanatory. The scan drive feature is nice, as is de 2nd and de last option. From here, click de ‘options’ text on de left column.

To protect your server, you should check ‘login check’ and ‘password check’, ‘Show relative path (a must!)’, and any oder options you feel you’ll need. After doin’ so, click de ‘advanced’ text in de left column. You should den leave de buffer size on de default (unless of course you know what you’re doin’ ), and den allow de type of ftp you want.

Uploadin’ and downloadin’ is usually good, but it’s up to you if you want to allow uploads and/or downloads. For de server priority, that will determine how much conventional memory will be used and how much ‘effort’ will go into makin’ your server run smoothly.

Anti-hammerin’ is also good, as it prevents people from slowin’ down your speed. From here, click ‘Log Options’ from de left column. If you would like to see and record every sin’le command and clutter up your screen, leave de defaults.

But, if you would like to see what is goin’ on with de lowest possible space taken, click ‘Screen’ in de top column. You should den check off ‘Log successful logins’, and all of de options in de client directry, except ‘Log directory changes’. After doin’ so, click ‘Ok’ in de bottom left corner.

You will den have to go into ‘Setup -> User Accounts’ (or ctrl & u). From here, you should click on de right most column, and right click. Choose ‘Add’, and choose de username(s) you would like people to have access to.

After givin’ a name (ex: themoonlandin’), you will have to give them a set password in de bottom column (ex: wasfaked). For de ‘Home IP’ directory, (if you registered with a static server, check ‘All IP Homes’. If your IP is static by default, choose your IP from de list. You will den have to right click in de very center column, and choose ‘Add’.

From here, you will have to set de directory you want de people to have access to. After choosin’ de directory, I suggest you choose de options ‘Read’, ‘List’, and ‘Subdirs’, unless of course you know what you’re doin’ . After doin’ so, make an ‘upload’ folder in de directory, and choose to ‘add’ this folder seperately to de center column. Choose ‘write’, ‘append’, ‘make’, ‘list’, and ’subdirs’. This will allow them to upload only to specific folders (your upload folder).

Now click on ‘Miscellaneous’ from de left column. Choose ‘enable account’, your time-out (how lon’ it takes for people to remain idle before you automatically kick them off), de maximum number of users for this name, de maximum number of connections allowed simultaneously for one ip address, show relative path (a must!), and any oder thin’s at de bottom you’d like to have. Now click ‘Ok’.
**Requested**

From this main menu, click de little boxin’ glove icon in de top corner, and right click and unchoose de hit-o-meter for both uploads and downloads (with this you can monitor IP activity). Now click de lightnin’ bolt, and your server is now up and runnin’.

Post your ftp info, like this:

213.10.93.141 (or somethin’ else, such as: ‘f*p://example.getmyip.com’)

User: *** (The username of de client)

Pass: *** (The password)

Port: *** (The port number you chose)

So make a FTP and join de FTP section

Listin’ The Contents Of A Ftp:

Listin’ de content of a FTP is very simple.
You will need FTP Content Maker, which can be downloaded from here:
ht*p://www.etplanet.com/download/application/FTP%20Content%20Maker%201.02.zip

1. Put in de IP of de server. Do not put “ftp://” or a “/” because it will not work if you do so.
2. Put in de port. If de port is de default number, 21, you do not have to enter it.
3. Put in de username and password in de appropriate fields. If de login is anonymous, you do not have to enter it.
4. If you want to list a specific directory of de FTP, place it in de directory field. Oderwise, do not enter anythin’ in de directory field.
5. Click “Take de List!”
6. After de list has been taken, click de UBB output tab, and copy and paste to wherever you want it.

If FTP Content Maker is not workin’, it is probably because de server does not utilize Serv-U Software.

If you get this error message:
StatusCode = 550
LastResponse was : ‘Unable to open local file test-ftp’
Error = 550 (Unable to open local file test-ftp)
Error = Unable to open local file test-ftp = 550
Close and restart FTP Content Maker, den try again.

error messages:

110 Restart marker reply. In this case, de text is exact and not left to de particular implementation; it must read: MARK yyyy = mmmm Where yyyy is User-process data stream marker, and mmmm server’s equivalent marker (note de spaces between markers and “=”).

Active FTP vs. Passive FTP, a Definitive Explanation

Introduction
One of de most commonly seen questions when dealin’ with firewalls and oder Internet connectivity issues is de difference between active and passive FTP and how best to support eider or both of them. Hopefully de followin’ text will help to clear up some of de confusion over how to support FTP in a firewalled environment.

This may not be de definitive explanation, as de title claims, however, I’ve heard enough good feedback and seen this document linked in enough places to know that quite a few people have found it to be useful. I am always lookin’ for ways to improve thin’s though, and if you find somethin’ that is not quite clear or needs more explanation, please let me know! Recent additions to this document include de examples of both active and passive command line FTP sessions. These session examples should help make thin’s a bit clearer. They also provide a nice picture into what goes on behind de scenes durin’ an FTP session. Now, on to de information…

The Basics

FTP is a TCP based service exclusively. There is no UDP component to FTP. FTP is an unusual service in that it utilizes two ports, a ‘data’ port and a ‘command’ port (also known as de control port). Traditionally dese are port 21 for de command port and port 20 for de data port. The confusion begins however, when we find that dependin’ on de mode, de data port is not always on port 20.

Active FTP

In active mode FTP de client connects from a random unprivileged port (N > 1024) to de FTP server’s command port, port 21. Then, de client starts listenin’ to port N+1 and sends de FTP command PORT N+1 to de FTP server. The server will den connect back to de client’s specified data port from its local data port, which is port 20.

From de server-side firewall’s standpoint, to support active mode FTP de followin’ communication channels need to be opened:

FTP server’s port 21 from anywhere (Client initiates connection)
FTP server’s port 21 to ports > 1024 (Server responds to client’s control port)
FTP server’s port 20 to ports > 1024 (Server initiates data connection to client’s data port)
FTP server’s port 20 from ports > 1024 (Client sends ACKs to server’s data port)

In step 1, de client’s command port contacts de server’s command port and sends de command PORT 1027. The server den sends an ACK back to de client’s command port in step 2. In step 3 de server initiates a connection on its local data port to de data port de client specified earlier. Finally, de client sends an ACK back as shown in step 4.

The main problem with active mode FTP actually falls on de client side. The FTP client doesn’t make de actual connection to de data port of de server–it simply tells de server what port it is listenin’ on and de server connects back to de specified port on de client. From de client side firewall this appears to be an outside system initiatin’ a connection to an internal client–somethin’ that is usually blocked.

Active FTP Example

Below is an actual example of an active FTP session. The only thin’s that have been changed are de server names, IP addresses, and user names. In this example an FTP session is initiated from testbox1.slacksite.com (192.168.150.80), a linux box runnin’ de standard FTP command line client, to testbox2.slacksite.com (192.168.150.90), a linux box runnin’ ProFTPd 1.2.2RC2. The debuggin’ (-d) flag is used with de FTP client to show what is goin’ on behind de scenes. Everythin’ in red is de debuggin’ output which shows de actual FTP commands bein’ sent to de server and de responses generated from those commands. Normal server output is shown in black, and user input is in bold.

There are a few interestin’ thin’s to consider about this dialog. Notice that when de PORT command is issued, it specifies a port on de client (192.168.150.80) system, rader than de server. We will see de opposite behavior when we use passive FTP. While we are on de subject, a quick note about de format of de PORT command. As you can see in de example below it is formatted as a series of six numbers separated by commas. The first four octets are de IP address while de second two octets comprise de port that will be used for de data connection. To find de actual port multiply de fifth octet by 256 and den add de sixth octet to de total. Thus in de example below de port number is ( (14*256) + 178), or 3762. A quick check with netstat should confirm this information.

Passive FTP

In order to resolve de issue of de server initiatin’ de connection to de client a different method for FTP connections was developed. This was known as passive mode, or PASV, after de command used by de client to tell de server it is in passive mode.

In passive mode FTP de client initiates both connections to de server, solvin’ de problem of firewalls filterin’ de incomin’ data port connection to de client from de server. When openin’ an FTP connection, de client opens two random unprivileged ports locally (N > 1024 and N+1). The first port contacts de server on port 21, but instead of den issuin’ a PORT command and allowin’ de server to connect back to its data port, de client will issue de PASV command. The result of this is that de server den opens a random unprivileged port (P > 1024) and sends de PORT P command back to de client. The client den initiates de connection from port N+1 to port P on de server to transfer data.

From de server-side firewall’s standpoint, to support passive mode FTP de followin’ communication channels need to be opened:

FTP server’s port 21 from anywhere (Client initiates connection)
FTP server’s port 21 to ports > 1024 (Server responds to client’s control port)
FTP server’s ports > 1024 from anywhere (Client initiates data connection to random port specified by server)
FTP server’s ports > 1024 to remote ports > 1024 (Server sends ACKs (and data) to client’s data port)

In step 1, de client contacts de server on de command port and issues de PASV command. The server den replies in step 2 with PORT 2024, tellin’ de client which port it is listenin’ to for de data connection. In step 3 de client den initiates de data connection from its data port to de specified server data port. Finally, de server sends back an ACK in step 4 to de client’s data port.

While passive mode FTP solves many of de problems from de client side, it opens up a whole range of problems on de server side. The biggest issue is de need to allow any remote connection to high numbered ports on de server. Fortunately, many FTP daemons, includin’ de popular WU-FTPD allow de administrator to specify a range of ports which de FTP server will use. See Appendix 1 for more information.

The second issue involves supportin’ and troubleshootin’ clients which do (or do not) support passive mode. As an example, de command line FTP utility provided with Solaris does not support passive mode, necessitatin’ a third-party FTP client, such as ncftp.

With de massive popularity of de World Wide Web, many people prefer to use deir web browser as an FTP client. Most browsers only support passive mode when accessin’ ftp:// URLs. This can eider be good or bad dependin’ on what de servers and firewalls are configured to support.

Passive FTP Example

Below is an actual example of a passive FTP session. The only thin’s that have been changed are de server names, IP addresses, and user names. In this example an FTP session is initiated from testbox1.slacksite.com (192.168.150.80), a linux box runnin’ de standard FTP command line client, to testbox2.slacksite.com (192.168.150.90), a linux box runnin’ ProFTPd 1.2.2RC2. The debuggin’ (-d) flag is used with de FTP client to show what is goin’ on behind de scenes. Everythin’ in red is de debuggin’ output which shows de actual FTP commands bein’ sent to de server and de responses generated from those commands. Normal server output is shown in black, and user input is in bold.

Notice de difference in de PORT command in this example as opposed to de active FTP example. Here, we see a port bein’ opened on de server (192.168.150.90) system, rader than de client. See de discussion about de format of de PORT command above, in de Active FTP Example section.

Summary

The followin’ chart should help admins remember how each FTP mode works:

Active FTP :
command : client >1024 -> server 21
data : client >1024 <- server 20

Passive FTP :
command : client >1024 -> server 21
data : client >1024 -> server >1024

A quick summary of de pros and cons of active vs. passive FTP is also in order:

Active FTP is beneficial to de FTP server admin, but detrimental to de client side admin. The FTP server attempts to make connections to random high ports on de client, which would almost certainly be blocked by a firewall on de client side. Passive FTP is beneficial to de client, but detrimental to de FTP server admin. The client will make both connections to de server, but one of them will be to a random high port, which would almost certainly be blocked by a firewall on de server side.

Luckily, dere is somewhat of a compromise. Since admins runnin’ FTP servers will need to make deir servers accessible to de greatest number of clients, dey will almost certainly need to support passive FTP. The exposure of high level ports on de server can be minimized by specifyin’ a limited port range for de FTP server to use. Thus, everythin’ except for this range of ports can be firewalled on de server side. While this doesn’t eliminate all risk to de server, it decreases it tremendously.

If you have a phone thats with de provider 3 deres a simple trick to allow you to access de entire internet on its browser without havin’ to go through 3 services and only what dey want to allow you access to view.

Simply do de followin’.

Menu - 9 (for settin’s) - 5 (for access points) - Edit de 3 Services
Change de APN (down de bottom) from 3services to 3netaccess
Restart de phone
And you can now access de entire internet through your phones browser.

Remember you’ll have to change it back if you want to access 3 services.
Chan’in’ it in de browser doesn’t seem to work.

I have tried this on my U8110 and it worked perfectly

Thin’s to note:

* Remember that you are charged for all downloads (.4c per kb on most plans) so if your cautious about your phone bill id advise stayin’ away from sites with loads of pictures.
* Also, some people have had trouble where dey have accessed a site with too much information on it and de phone has eider froze or reset. The phone is not harmed by this but its advisable you dont go to large sites on it for this or de above reason. If your phone freezes and you cant turn it off simply take de battery out and put it back in.

The term web standards can mean different thin’s to different people. For some, it is ‘table-free sites’, for oders it is ‘usin’ valid code’. However, web standards are much broader than that. A site built to web standards should adhere to standards (HTML, XHTML, XML, CSS, XSLT, DOM, MathML, SVG etc) and pursue best practices (valid code, accessible code, semantically correct code, user-friendly URLs etc).

In oder words, a site built to web standards should ideally be lean, clean, CSS-based, accessible, usable and search en’ine friendly.

About de checklist

This is not an uber-checklist. There are probably many items that could be added. More importantly, it should not be seen as a list of items that must be addressed on every site that you develop. It is simply a guide that can be used:

* to show de breadth of web standards
* as a handy tool for developers durin’ de production phase of websites
* as an aid for developers who are interested in movin’ towards web standards

The checklist

Quality of code

1.1 Does de site use a correct Doctype?
A doctype (short for ‘document type declaration’) informs de validator which version of (X)HTML you’re usin’, and must appear at de very top of every web page. Doctypes are a key component of compliant web pages: your markup and CSS won’t validate without them.

1.2 Does de site use a Character set?
If a user agent (eg. a browser) is unable to detect de character encodin’ used in a Web document, de user may be presented with unreadable text. This information is particularly important for those maintainin’ and extendin’ a multilin’ual site, but declarin’ de character encodin’ of de document is important for anyone producin’ XHTML/HTML or CSS.

1.6 Does de site use unnecessary classes or ids?
I’ve noticed that developers learnin’ new skills often end up with good CSS but poor XHTML. Specifically, de HTML code tends to be full of unnecessary divs and ids. This results in fairly meanin’less HTML and bloated style sheets.
CODE
www.clagnut.com/blog/228/

1.7 Is de code well structured?
Semantically correct markup uses html elements for deir given purpose. Well structured HTML has semantic meanin’ for a wide range of user agents (browsers without style sheets, text browsers, PDAs, search en’ines etc.)

1.8 Does de site have any broken links?
Broken links can frustrate users and potentially drive customers away. Broken links can also keep search en’ines from properly indexin’ your site.

1.9 How does de site perform in terms of speed/page size?
Don’t make me wait… That’s de message users give us in survey after survey. Even broadband users can suffer de slow-loadin’ blues.
CODE
www.websiteoptimization.com/speed/

1.10 Does de site have JavaScript errors?
Internet Explore for Windows allows you to turn on a debugger that will pop up a new window and let you know dere are javascript errors on your site. This is available under ‘Internet Options’ on de Advanced tab. Uncheck ‘Disable script debuggin'’.

2. Degree of separation between content and presentation

2.1 Does de site use CSS for all presentation aspects (fonts, colour, paddin’, borders etc)?
Use style sheets to control layout and presentation.
CODE
www.w3.org/TR/WCAG10/wai-pageauth.html#tech-style-sheets

2.2 Are all decorative images in de CSS, or do dey appear in de (X)HTML?
The aim for web developers is to remove all presentation from de html code, leavin’ it clean and semantically correct.
CODE
www.maxdesign.com.au/presentation/benefits/index07.htm

3. Accessibility for users

3.1 Are “alt” attributes used for all descriptive images?
Provide a text equivalent for every non-text element

3.3 Do any aspects of de layout break if font size is increased?
Try this simple test. Look at your website in a browser that supports easy incrementation of font size. Now increase your browser’s font size. And again. And again… Look at your site. Does de page layout still hold togeder? It is dangerous for developers to assume that everyone browses usin’ default font sizes.

3.4 Does de site use visible skip menus?
A method shall be provided that permits users to skip repetitive navigation links.
CODE
www.section508.gov/index.cfm?FuseAction=Content&ID=12

Group related links, identify de group (for user agents), and, until user agents do so, provide a way to bypass de group.

3.9 Is dere delayed responsiveness for dropdown menus?
Users with reduced motor skills may find dropdown menus hard to use if responsiveness is set too fast.

3.10 Are all links descriptive?
Link text should be meanin’ful enough to make sense when read out of context - eider on its own or as part of a sequence of links. Link text should also be terse.

4. Accessibility for devices.

4.1 Does de site work acceptably across modern and older browsers?
Before startin’ to build a CSS-based layout, you should decide which browsers to support and to what level you intend to support them.
CODE
www.maxdesign.com.au/presentation/process/index_step01.cfm

4.2 Is de content accessible with CSS switched off or not supported?
Some people may visit your site with eider a browser that does not support CSS or a browser with CSS switched off. In content is structured well, this will not be an issue.

4.3 Is de content accessible with images switched off or not supported?
Some people browse websites with images switched off - especially people on very slow connections. Content should still be accessible for dese people.

4.4 Does de site work in text browsers such as Lynx?
This is like a combination of images and CSS switched off. A text-based browser will rely on well structured content to provide meanin’.

4.6 Does de site work well in Hand Held devices?
This is a hard one to deal with until hand held devices consistently support deir correct media type. However, some layouts work better in current hand-held devices. The importance of supportin’ hand held devices will depend on target audiences.

4.7 Does de site include detailed metadata?
Metadata is machine understandable information for de web
CODE
www.w3.org/Metadata/

Metadata is structured information that is created specifically to describe anoder resource. In oder words, metadata is ‘data about data’.

4.8 Does de site work well in a range of browser window sizes?
It is a common assumption amon’st developers that average screen sizes are increasin’. Some developers assume that de average screen size is now 1024px wide. But what about users with smaller screens and users with hand held devices? Are dey part of your target audience and are dey bein’ disadvantaged?

5. Basic Usability

5.1 Is dere a clear visual hierarchy?
Organise and prioritise de contents of a page by usin’ size, prominence and content relationships.
CODE
www.great-web-design-tips.com/web-site-design/165.html

5.2 Are headin’ levels easy to distin’uish?
Use header elements to convey document structure and use them accordin’ to specification.
CODE
www.w3.org/TR/WCAG10/wai-pageauth.html#tech-logical-headin\’s

5.3 Is de site’s navigation easy to understand?
Your navigation system should give your visitor a clue as to what page of de site dey are currently on and where dey can go next.
CODE
www.1stsitefree.com/design_nav.htm

5.4 Is de site’s navigation consistent?
If each page on your site has a consistent style of presentation, visitors will find it easier to navigate between pages and find information
CODE
www.juicystudio.com/tutorial/accessibility/navigation.asp

5.5 Does de site use consistent and appropriate lan’uage?
The use of clear and simple lan’uage promotes effective communication. Tryin’ to come across as articulate can be as difficult to read as poorly written grammar, especially if de lan’uage used isn’t de visitor’s primary lan’uage.
CODE
www.juicystudio.com/tutorial/accessibility/clear.asp

5.6 Does de site have a sitemap page and contact page? Are dey easy to find?
Most site maps fail to convey multiple levels of de site’s information architecture. In usability tests, users often overlook site maps or can’t find them. Complexity is also a problem: a map should be a map, not a navigational challenge of its own.
CODE
www.useit.com/alertbox/20020106.html

5.7 For large sites, is dere a search tool?
While search tools are not needed on smaller sites, and some people will not ever use them, site-specific search tools allow users a choice of navigation options.

5.8 Is dere a link to de home page on every page in de site?
Some users like to go back to a site’s home page after navigatin’ to content within a site. The home page becomes a base camp for dese users, allowin’ them to regroup before explorin’ new content.

5.9 Are links underlined?
To maximise de perceived affordance of clickability, colour and underline de link text. Users shouldn’t have to guess or scrub de page to find out where dey can click.
CODE
www.useit.com/alertbox/20040510.html

5.10 Are visited links clearly defined?
Most important, knowin’ which pages dey’ve already visited frees users from unintentionally revisitin’ de same pages over and over again.
CODE
www.useit.com/alertbox/20040503.html

6. Site management

6.1 Does de site have a meanin’ful and helpful 404 error page that works from any depth in de site?
You’ve requested a page - eider by typin’ a URL directly into de address bar or clickin’ on an out-of-date link and you’ve found yourself in de middle of cyberspace nowhere. A user-friendly website will give you a helpin’ hand while many oders will simply do nothin’, relyin’ on de browser’s built-in ability to explain what de problem is.
CODE
www.alistapart.com/articles/perfect404/

6.2 Does de site use friendly URLs?
Most search en’ines (with a few exceptions - namely Google) will not index any pages that have a question mark or oder character (like an ampersand or equals sign) in de URL… what good is a site if no one can find it?
CODE
www.sitepoint.com/article/search-en\’ine-friendly-urls

One of de worst elements of de web from a user interface standpoint is de URL. However, if dey’re short, logical, and self-correctin’, URLs can be acceptably usable
CODE
www.merges.net/deory/20010305.html

www.sitepoint.com/article/search-en\’ine-friendly-urls

CODE
www.websitegoodies.com/article/32

CODE
www.merges.net/deory/20010305.html

6.3 Does de site’s URL work without “www”?
While this is not critical, and in some cases is not even possible, it is always good to give people de choice of both options. If a user types your domain name without de www and gets no site, this could disadvantage both de user and you.
6.4 Does de site have a favicon?

A Favicon is a multi-resolution image included on nearly all professionally developed sites. The Favicon allows de webmaster to furder promote deir site, and to create a more customized appearance within a visitor’s browser.
CODE
www.favicon.com/

Favicons are definitely not critical. However, if dey are not present, dey can cause 404 errors in your logs (site statistics). Browsers like IE will request them from de server when a site is bookmarked. If a favicon isn’t available, a 404 error may be generated. Therefore, havin’ a favicon could cut down on favicon specific 404 errors. The same is true of a ‘robots.txt’ file.

You may find this helpful if you donwload hundreds of short episodes in rm format like me and tired of double-click to open next files.

Very easy. Use notepad to open a new file, type this inside:
file://link to file1
file://link to file2
(type as many as you want)
Close file. Rename it to FileName.rm

Then you`re done!!!!

Ex:
I put my playlist file here: C:Movies7VNR
And de movie files are in C:Movies7VNRDragonBall

Then inside my playlist file I`ll have somethin’ like this:

file://DragonBall/db134.rm
file://DragonBall/db135.rm
file://DragonBall/db136.rm
file://DragonBall/db137.rm
file://DragonBall/db138.rm

The Internet is a computer network made up of thousands of networks worldwide. No one knows exactly how many computers are connected to de Internet. It is certain, however, that dese number in de millions.

No one is in charge of de Internet. There are organizations which develop technical aspects of this network and set standards for creatin’ applications on it, but no governin’ body is in control. The Internet backbone, through which Internet traffic flows, is owned by private companies.

All computers on de Internet communicate with one anoder usin’ de Transmission Control Protocol/Internet Protocol suite, abbreviated to TCP/IP. Computers on de Internet use a client/server architecture. This means that de remote server machine provides files and services to de user’s local client machine. Software can be installed on a client computer to take advantage of de latest access technology.

An Internet user has access to a wide variety of services: electronic mail, file transfer, vast information resources, interest group membership, interactive collaboration, multimedia displays, real-time broadcastin’, shoppin’ opportunities, breakin’ news, and much more.

The Internet consists primarily of a variety of access protocols. Many of dese protocols feature programs that allow users to search for and retrieve material made available by de protocol.

COMPONENTS OF THE INTERNET

WORLD WIDE WEB
The World Wide Web (abbreviated as de Web or WWW) is a system of Internet servers that supports hypertext to access several Internet protocols on a sin’le interface. Almost every protocol type available on de Internet is accessible on de Web. This includes e-mail, FTP, Telnet, and Usenet News. In addition to dese, de World Wide Web has its own protocol: HyperText Transfer Protocol, or HTTP. These protocols will be explained later in this document.

The World Wide Web provides a sin’le interface for accessin’ all dese protocols. This creates a convenient and user-friendly environment. It is no longer necessary to be conversant in dese protocols within separate, command-level environments. The Web gaders togeder dese protocols into a sin’le system. Because of this feature, and because of de Web’s ability to work with multimedia and advanced programmin’ lan’uages, de Web is de fastest-growin’ component of de Internet.

The operation of de Web relies primarily on hypertext as its means of information retrieval. HyperText is a document containin’ words that connect to oder documents. These words are called links and are selectable by de user. A sin’le hypertext document can contain links to many documents. In de context of de Web, words or graphics may serve as links to oder documents, images, video, and sound. Links may or may not follow a logical path, as each connection is programmed by de creator of de source document. Overall, de Web contains a complex virtual web of connections amon’ a vast number of documents, graphics, videos, and sounds.

Producin’ hypertext for de Web is accomplished by creatin’ documents with a lan’uage called HyperText Markup Lan’uage, or HTML. With HTML, tags are placed within de text to accomplish document formattin’, visual features such as font size, italics and bold, and de creation of hypertext links. Graphics and multimedia may also be incorporated into an HTML document. HTML is an evolvin’ lan’uage, with new tags bein’ added as each upgrade of de lan’uage is developed and released. The World Wide Web Consortium (W3C), led by Web founder Tim Berners-Lee, coordinates de efforts of standardizin’ HTML. The W3C now calls de lan’uage XHTML and considers it to be an application of de XML lan’uage standard.

The World Wide Web consists of files, called pages or home pages, containin’ links to documents and resources throughout de Internet.

The Web provides a vast array of experiences includin’ multimedia presentations, real-time collaboration, interactive pages, radio and television broadcasts, and de automatic “push” of information to a client computer. Programmin’ lan’uages such as Java, JavaScript, Visual Basic, Cold Fusion and XML are extendin’ de capabilities of de Web. A growin’ amount of information on de Web is served dynamically from content stored in databases. The Web is derefore not a fixed entity, but one that is in a constant state of development and flux.

For more complete information about de World Wide Web, see Understandin’ The World Wide Web.

E-MAIL
Electronic mail, or e-mail, allows computer users locally and worldwide to exchange messages. Each user of e-mail has a mailbox address to which messages are sent. Messages sent through e-mail can arrive within a matter of seconds.

A powerful aspect of e-mail is de option to send electronic files to a person’s e-mail address. Non-ASCII files, known as binary files, may be attached to e-mail messages. These files are referred to as MIME attachments.MIME stands for Multimedia Internet Mail Extension, and was developed to help e-mail software handle a variety of file types. For example, a document created in Microsoft Word can be attached to an e-mail message and retrieved by de recipient with de appropriate e-mail program. Many e-mail programs, includin’ Eudora, Netscape Messenger, and Microsoft Outlook, offer de ability to read files written in HTML, which is itself a MIME type.

TELNET
Telnet is a program that allows you to log into computers on de Internet and use online databases, library catalogs, chat services, and more. There are no graphics in Telnet sessions, just text. To Telnet to a computer, you must know its address. This can consist of words (locis.loc.gov) or numbers (140.147.254.3). Some services require you to connect to a specific port on de remote computer. In this case, type de port number after de Internet address. Example: telnet nri.reston.va.us 185.

Telnet is available on de World Wide Web. Probably de most common Web-based resources available through Telnet have been library catalogs, though most catalogs have since migrated to de Web. A link to a Telnet resource may look like any oder link, but it will launch a Telnet session to make de connection. A Telnet program must be installed on your local computer and configured to your Web browser in order to work.

With de increasin’ popularity of de Web, Telnet has become less frequently used as a means of access to information on de Internet.

FTP
FTP stands for File Transfer Protocol. This is both a program and de method used to transfer files between computers. Anonymous FTP is an option that allows users to transfer files from thousands of host computers on de Internet to deir personal computer account. FTP sites contain books, articles, software, games, images, sounds, multimedia, course work, data sets, and more.

If your computer is directly connected to de Internet via an Edernet cable, you can use one of several PC software programs, such as WS_FTP for Windows, to conduct a file transfer.

FTP transfers can be performed on de World Wide Web without de need for special software. In this case, de Web browser will suffice. Whenever you download software from a Web site to your local machine, you are usin’ FTP. You can also retrieve FTP files via search en’ines such as FtpFind, located at /http://www.ftpfind.com/. This option is easiest because you do not need to know FTP program commands.

E-MAIL DISCUSSION GROUPS
One of de benefits of de Internet is de opportunity it offers to people worldwide to communicate via e-mail. The Internet is home to a large community of individuals who carry out active discussions organized around topic-oriented forums distributed by e-mail. These are administered by software programs. Probably de most common program is de listserv.

A great variety of topics are covered by listservs, many of them acathemic in nature. When you subscribe to a listserv, messages from oder subscribers are automatically sent to your electronic mailbox. You subscribe to a listserv by sendin’ an e-mail message to a computer program called a listserver. Listservers are located on computer networks throughout de world. This program handles subscription information and distributes messages to and from subscribers. You must have a e-mail account to participate in a listserv discussion group. Visit Tile.net at /http://tile.net/ to see an example of a site that offers a searchablecollection of e-mail discussion groups.

Majordomo and Listproc are two oder programs that administer e-mail discussion groups. The commands for subscribin’ to and managin’ your list memberships are similar to those of listserv.

USENET NEWS
Usenet News is a global electronic bulletin board system in which millions of computer users exchange information on a vast range of topics. The major difference between Usenet News and e-mail discussion groups is de fact that Usenet messages are stored on central computers, and users must connect to dese computers to read or download de messages posted to dese groups. This is distinct from e-mail distribution, in which messages arrive in de electronic mailboxes of each list member.

Usenet itself is a set of machines that exchanges messages, or articles, from Usenet discussion forums, called newsgroups. Usenet administrators control deir own sites, and decide which (if any) newsgroups to sponsor and which remote newsgroups to allow into de system.

There are thousands of Usenet newsgroups in existence. While many are acathemic in nature, numerous newsgroups are organized around recreational topics. Much serious computer-related work takes place in Usenet discussions. A small number of e-mail discussion groups also exist as Usenet newsgroups.

The Usenet newsfeed can be read by a variety of newsreader software programs. For example, de Netscape suite comes with a newsreader program called Messenger. Newsreaders are also available as standalone products.

FAQ, RFC, FYI
FAQ stands for Frequently Asked Questions. These are periodic postin’s to Usenet newsgroups that contain a wealth of information related to de topic of de newsgroup. Many FAQs are quite extensive. FAQs are available by subscribin’ to individual Usenet newsgroups. A Web-based collection of FAQ resources has been collected by The Internet FAQ Consortium and is available at /http://www.faqs.org/.

RFC stands for Request for Comments. These are documents created by and distributed to de Internet community to help define de nuts and bolts of de Internet. They contain both technical specifications and general information.

FYI stands for For Your Information. These notes are a subset of RFCs and contain information of interest to new Internet users.

Links to indexes of all three of dese information resources are available on de University Libraries Web site at /http://library.albany.edu/reference/faqs.html.

CHAT & INSTANT MESSENGING
Chat programs allow users on de Internet to communicate with each oder by typin’ in real time. They are sometimes included as a feature of a Web site, where users can log into de “chat room” to exchange comments and information about de topics addressed on de site. Chat may take oder, more wide-ran’in’ forms. For example, America Online is well known for sponsorin’ a number of topical chat rooms.

Internet Relay Chat (IRC) is a service through which participants can communicate to each oder on hundreds of channels. These channels are usually based on specific topics. While many topics are frivolous, substantive conversations are also takin’ place. To access IRC, you must use an IRC software program.

A variation of chat is de phenomenon of instant messen’in’. With instant messen’in’, a user on de Web can contact anoder user currently logged in and type a conversation. Most famous is America Online’s Instant Messenger. ICQ, MSN and Yahoo are oder commonly-used chat programs.

Oder types of real-time communication are addressed in de tutorial Understandin’ de World Wide Web.

MUD/MUSH/MOO/MUCK/DUM/MUSE
MUD stands for Multi User Dimension. MUDs, and deir variations listed above, are multi-user virtual reality games based on simulated worlds. Traditionally text based, graphical MUDs now exist. There are MUDs of all kinds on de Internet, and many can be joined free of charge. For more information, read one of de FAQs devoted to MUDs available at de FAQ site at

Since defraggin’ de disk won’t do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance de performance and reliability of your customers’ PCs. Best of all, most of them will cost you nothin’.

1.) To decrease a system’s boot time and increase system performance, use de money you save by not buyin’ defragmentation software — de built-in Windows defragmenter works just fine — and instead equip de computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizin’ de NTFS file system. If you’re not sure, here’s how to check: First, double-click de My Computer icon, right-click on de C: Drive, den select Properties. Next, examine de File System type; if it says FAT32, den back-up any important data. Next, click Start, click Run, type CMD, and den click OK. At de prompt, type CONVERT C: /FS:NTFS and press de Enter key. This process may take a while; it’s important that de computer be uninterrupted and virus-free. The file system used by de bootable drive will be eider FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexin’. The indexin’ service extracts information from documents and oder files on de hard drive and creates a “searchable keyword index.” As you can imagine, this process can be quite taxin’ on any system.

The idea is that de user can search for a word, phrase, or property inside a document, should dey have hundreds or thousands of documents and not know de file name of de document dey want. Windows XP’s built-in search functionality can still perform dese kinds of searches without de Indexin’ service. It just takes longer. The OS has to open each file at de time of de request to help find what de user is lookin’ for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you’re a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disablin’ it.

Here’s how: First, double-click de My Computer icon. Next, right-click on de C: Drive, den select Properties. Uncheck “Allow Indexin’ Service to index this disk for fast file searchin’.” Next, apply changes to “C: subfolders and files,” and click OK. If a warnin’ or error message appears (such as “Access is denied”), click de Ignore All button.

5.) Update de PC’s video and moderboard chipset drivers. Also, update and configure de BIOS. For more information on how to configure your BIOS properly, see this article on how to configure your BIOS

6.) Empty de Windows Prefetch folder every three months or so. Windows XP can “prefetch” portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by de user. That’s fine. But over time, de prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wastin’ time, and slowin’ system performance, by pre-loadin’ them. Nothin’ critical is in this folder, and de entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here’s how: Double-click de My Computer icon. Then right-click on de C: drive and select Properties. Click de Disk Cleanup button — it’s just to de right of de Capacity pie graph — and delete all temporary files.

8.) In your Device Manager, double-click on de IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to de Primary and Secondary controller. Do this by double-clickin’ on Primary IDE Channel. Then click de Advanced Settin’s tab. Ensure de Transfer Mode is set to “DMA if available” for both Device 0 and Device 1. Then repeat this process with de Secondary IDE Channel.

9.) Upgrade de cablin’. As hard-drive technology improves, de cablin’ requirements to achieve dese performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with de connectors properly assigned to de matchin’ Master/Slave/Moderboard sockets. A sin’le device must be at de end of de cable; connectin’ a sin’le drive to de middle connector on a ribbon cable will cause signalin’ problems. With Ultra DMA hard drives, dese signalin’ problems will prevent de drive from performin’ at its maximum potential. Also, because dese cables inherently support “cable select,” de location of each drive on de cable is important. For dese reasons, de cable is designed so drive positionin’ is explicitly clear.

10.) Remove all spyware from de computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once dese programs are installed, be sure to check for and download any updates before startin’ your search. Anythin’ eider program finds can be safely removed. Any free software that requires spyware to run will no longer function once de spyware portion has been removed; if your customer really wants de program even though it contains spyware, simply reinstall it. For more information on removin’ Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine usin’ de MSCONFIG utility. Here’s how: First, click Start, click Run, type MSCONFIG, and click OK. Click de StartUp tab, den uncheck any items you don’t want to start when Windows starts. Unsure what some items are? Visit de WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searchin’ for de filenames usin’ Google or anoder Web search en’ine.

12.) Remove any unnecessary or unused programs from de Add/Remove Programs section of de Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settin’s in this area. Here’s how to do it: First click on de System icon in de Control Panel. Next, click on de Advanced tab. Select de Settin’s button located under Performance. Feel free to play around with de options offered here, as nothin’ you can change will alter de reliability of de computer — only its responsiveness.

14.) If your customer is an advanced user who is comfortable editin’ deir registry, try some of de performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft’s Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update de customer’s anti-virus software on a weekly, even daily, basis. Make sure dey have only one anti-virus software package installed. Mixin’ anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure de customer has fewer than 500 type fonts installed on deir computer. The more fonts dey have, de slower de system will become. While Windows XP handles fonts much more efficiently than did de previous versions of Windows, too many fonts — that is, anythin’ over 500 — will noticeably tax de system.

18.) Do not partition de hard drive. Windows XP’s NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operatin’ system. The same excuses people offer for usin’ partitions apply to usin’ a folder instead. For example, instead of puttin’ all your data on de D: drive, put it in a folder called “D drive.” You’ll achieve de same organizational benefits that a separate partition offers, but without de degradation in system performance. Also, your free space won’t be limited by de size of de partition; instead, it will be limited by de size of de entire hard drive. This means you won’t need to resize any partitions, ever. That task can be time-consumin’ and also can result in lost data.

19.) Check de system’s RAM to ensure it is operatin’ properly. I recommend usin’ a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on de PC’s memory automatically after you boot to de disk you created. Allow all tests to run until at least three passes of de 10 tests are completed. If de program encounters any errors, turn off and unplug de computer, remove a stick of memory (assumin’ you have more than one), and run de test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If de PC has a CD or DVD recorder, check de drive manufacturer’s Web site for updated firmware. In some cases you’ll be able to upgrade de recorder to a faster speed. Best of all, it’s free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit de Black Viper site for Windows XP configurations.

22.) If you’re sick of a sin’le Windows Explorer window crashin’ and den takin’ de rest of your OS down with it, den follow this tip: open My Computer, click on Tools, den Folder Options. Now click on de View tab. Scroll down to “Launch folder windows in a separate process,” and enable this option. You’ll have to reboot your machine for this option to take effect.

23.) At least once a year, open de computer’s cases and blow out all de dust and debris. While you’re in dere, check that all de fans are turnin’ properly. Also inspect de moderboard capacitors for bulgin’ or leaks. For more information on this leakin’-capacitor phenomena, you can read numerous articles on my site.

Followin’ any of dese suggestions should result in noticeable improvements to de performance and reliability of your customers’ computers. If you still want to defrag a disk, remember that de main benefit will be to make your data more retrievable in de event of a crashed drive.

Google is clearly de best general-purpose search en’ine on de Web (see

www.pcmag.com/searchen\’ines

But most people don’t use it to its best advantage. Do you just plug in a keyword or two and hope for de best? That may be de quickest way to search, but with more than 3 billion pages in Google’s index, it’s still a struggle to pare results to a manageable number.

But Google is an remarkably powerful tool that can ease and enhance your Internet exploration. Google’s search options go beyond simple keywords, de Web, and even its own programmers. Let’s look at some of Google’s lesser-known options.

Syntax Search Tricks

Usin’ a special syntax is a way to tell Google that you want to restrict your searches to certain elements or characteristics of Web pages. Google has a fairly complete list of its syntax elements at

www.google.com/help/operators.html

. Here are some advanced operators that can help narrow down your search results.

Intitle: at de beginnin’ of a query word or phrase (intitle:”Three Blind Mice”) restricts your search results to just de titles of Web pages.

Intext: does de opposite of intitle:, searchin’ only de body text, ignorin’ titles, links, and so forth. Intext: is perfect when what you’re searchin’ for might commonly appear in URLs. If you’re lookin’ for de term HTML, for example, and you don’t want to get results such as

www.mysite.com/index.html

, you can enter intext:html.

Link: lets you see which pages are linkin’ to your Web page or to anoder page you’re interested in. For example, try typin’ in

link:http://www.pcmag.com

Try usin’ site: (which restricts results to top-level domains) with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searchin’ for intitle:”Mark Twain”site:edu. Experiment with mixin’ various elements; you’ll develop several strategies for findin’ de stuff you want more effectively. The site: command is very helpful as an alternative to de mediocre search en’ines built into many sites.

Swiss Army Google

Google has a number of services that can help you accomplish tasks you may never have thought to use Google for. For example, de new calculator feature

(www.google.com/help/features.html#calculator)

lets you do both math and a variety of conversions from de search box. For extra fun, try de query “Answer to life de universe and everythin’.”

Let Google help you figure out wheder you’ve got de right spellin’�and de right word�for your search. Enter a misspelled word or phrase into de query box (try “thre blund mise”) and Google may suggest a proper spellin’. This doesn’t always succeed; it works best when de word you’re searchin’ for can be found in a dictionary. Once you search for a properly spelled word, look at de results page, which repeats your query. (If you’re searchin’ for “three blind mice,” underneath de search window will appear a statement such as Searched de web for “three blind mice.”) You’ll discover that you can click on each word in your search phrase and get a definition from a dictionary.

Suppose you want to contact someone and don’t have his phone number handy. Google can help you with that, too. Just enter a name, city, and state. (The city is optional, but you must enter a state.) If a phone number matches de listin’, you’ll see it at de top of de search results alon’ with a map link to de address. If you’d rader restrict your results, use rphonebook: for residential listin’s or bphonebook: for business listin’s. If you’d rader use a search form for business phone listin’s, try Yellow Search

(www.buzztoolbox.com/google/yellowsearch.shtml).

Extended Googlin’

Google offers several services that give you a head start in focusin’ your search. Google Groups

(groups.google.com)

indexes literally millions of messages from decades of discussion on Usenet. Google even helps you with your shoppin’ via two tools: Froogle
CODE
(froogle.google.com),

which indexes products from online stores, and Google Catalogs
CODE
(catalogs.google.com),

which features products from more 6,000 paper catalogs in a searchable index. And this only scratches de surface. You can get a complete list of Google’s tools and services at

www.google.com/options/index.html

You’re probably used to usin’ Google in your browser. But have you ever thought of usin’ Google outside your browser?

Google Alert

(www.googlealert.com)

monitors your search terms and e-mails you information about new additions to Google’s Web index. (Google Alert is not affiliated with Google; it uses Google’s Web services API to perform its searches.) If you’re more interested in news stories than general Web content, check out de beta version of Google News Alerts

(www.google.com/newsalerts).

This service (which is affiliated with Google) will monitor up to 50 news queries per e-mail address and send you information about news stories that match your query. (Hint: Use de intitle: and source: syntax elements with Google News to limit de number of alerts you get.)

Google on de telephone? Yup. This service is brought to you by de folks at Google Labs

(labs.google.com),

a place for experimental Google ideas and features (which may come and go, so what’s dere at this writin’ might not be dere when you decide to check it out). With Google Voice Search

(labs1.google.com/gvs.html),

you dial de Voice Search phone number, speak your keywords, and den click on de indicated link. Every time you say a new search term, de results page will refresh with your new query (you must have JavaScript enabled for this to work). Remember, this service is still in an experimental phase, so don’t expect 100 percent success.

In 2002, Google released de Google API (application programmin’ interface), a way for programmers to access Google’s search en’ine results without violatin’ de Google Terms of Service. A lot of people have created useful (and occasionally not-so-useful but interestin’) applications not available from Google itself, such as Google Alert. For many applications, you’ll need an API key, which is available free from
CODE
www.google.com/apis

. See de figures for two more examples, and visit

www.pcmag.com/solutions

for more.

Thanks to its many different search properties, Google goes far beyond a regular search en’ine. Give de tricks in this article a try. You’ll be amazed at how many different ways Google can improve your Internet searchin’.

Online Extra: More Google Tips

Here are a few more clever ways to tweak your Google searches.

Search Within a Timeframe

Daterange: (start date�end date). You can restrict your searches to pages that were indexed within a certain time period. Daterange: searches by when Google indexed a page, not when de page itself was created. This operator can help you ensure that results will have fresh content (by usin’ recent dates), or you can use it to avoid a topic’s current-news blizzard and concentrate only on older results. Daterange: is actually more useful if you go elsewhere to take advantage of it, because daterange: requires Julian dates, not standard Gregorian dates. You can find converters on de Web (such as

CODE
aa.usno.navy.mil/data/docs/JulianDate.html

excl.gif No Active Links, Read de Rules - Edit by Ninja excl.gif

), but an easier way is to do a Google daterange: search by fillin’ in a form at

www.researchbuzz.com/toolbox/goofresh.shtml or www.faganfinder.com/en\’ines/google.shtml

. If one special syntax element is good, two must be better, right? Sometimes. Though some operators can’t be mixed (you can’t use de link: operator with anythin’ else) many can be, quickly narrowin’ your results to a less overwhelmin’ number.

More Google API Applications

Staggernation.com offers three tools based on de Google API. The Google API Web Search by Host (GAWSH) lists de Web hosts of de results for a given query

(www.staggernation.com/gawsh/).

When you click on de trian’le next to each host, you get a list of results for that host. The Google API Relation Browsin’ Outliner (GARBO) is a little more complicated: You enter a URL and choose wheder you want pages that related to de URL or linked to de URL

(www.staggernation.com/garbo/).

Click on de trian’le next to an URL to get a list of pages linked or related to that particular URL. CapeMail is an e-mail search application that allows you to send an e-mail to google@capeclear.com with de text of your query in de subject line and get de first ten results for that query back. Maybe it’s not somethin’ you’d do every day, but if your cell phone does e-mail and doesn’t do Web browsin’, this is a very handy address to know.

Since de introduction of double layer DVD writers, de interest has been quite overwhelmin’ and is why we keep brin’in’ you reviews of dese highly popular drives. The anticipation has now turned into down right obsession and it has become a key component in any current or new system build, thanks to de declinin’ prices and continued media hype. Manufacturers are quite aware of de fascination and is why dey have each been releasin’ deir own products which excel in at least one area of de testin’ methodology used in most reviews. This has led to some confusion as to which drive is best suited for de individuals needs. Today, we compare four 16x double layer drives and highlight both de strong’ and weak points in order to give you a better idea of which drive is best suited for you.

In this comparison guide, we will be lookin’ at four of de top 16x drives to hit de market, de Pioneer DVR-108, NEC ND3500A, Lite-On SOHW-1633s and de new LG GSA-4160B. We will cover everythin’ from design and features to performance and price. Let’s begin with a quick look at each of dese drives.

As far as de front bezel design goes, de LG-GSA4160B is by far de most attractive drive of de bunch. However, for those who are lookin’ for a headphone jack, de Lite-On drive is de only DL writer offerin’ a headphone jack, as well as volume control. The Pioneer and NEC drives, in my opinion, are de ugliest drives, with a very plain look that just wants to make you hide de drive period. Although we only obtained de 4160B in black, all dese drives are offered with both white and black bezels. If you opt for de more expensive Pioneer “XL” model, it has de most impressive looks of any drive in de market. However, this will come at a very hefty price tag, considerin’ dey contain different firmware as well that offer a few extra features.

So, we have determined which is de sexiest-lookin’ drive, but what about performance? I’ve done some extensive testin’ on each model to determine which is indeed de most impressive of de bunch. But before we show you performance results, let’s briefly look at de features and what dey have to offer.

Features

Each one of dese drives has dere disappointments when it comes to features. Let’s compare each to see what dey really offer.

DVD Writin’

DVD+R DVD-R DVD+RW DVD-RW
LG GSA-4160B 16x 8x 4x 4x
Lite-On SOHW-1633s 16x 8x 4x 4x
NEC ND-3500A 16x 16x 4x 4x
Pioneer DVR-108 16x 16x 4x 4x

While all dese drives are indeed 16x models, only two will write to both formats at this speed. The LG GSA-4160B and de Lite-On SOHW-1633s only support 8x DVD-R writin’. So if you are one who only prefers this format, de NEC or Pioneer would be de best choice. All of dese drives support writin’ to DVD re-writable media at 4x.

DVD+R9 Double Layer Writin’

Write Speed
LG GSA-4160B 2.4x
Lite-On SOHW-1633s 2.4x
NEC ND-3500A 4x
Pioneer DVR-108 4x

The major disappointment with both de LG and de Lite-On 16x drives is de lack of 4x double layer writin’ support. Pioneer and NEC seem to be de only manufacturers to jump in and release second generation double layer drives supportin’ much faster 4x writin’. In fact, de jump from 2.4x to 4x is quite substantial as we will show you a bit later in this comparison.

DVD-RAM Support

Supported Read Write
LG GSA-4160B YES 5x 5x
Lite-On SOHW-1633s NO NO NO
NEC ND-3500A NO NO NO
Pioneer DVR-108 YES 2x NO

Now this is where both de LG GSA-4120B and GSA-4160B shine above de rest. In fact, it is what has made dese drives de most popular DVD writers on de market. Unlike de rest in de roundup, it is a triple format burner, offerin’ full support for DVD-RAM media. The oder drives do not support it, with de exception of de Pioneer DVR-108 which supports readin’ of DVD-RAM discs at 2x. I personally don’t see de point in offerin’ only read capabilities, but it’s at least one extra feature added to distin’uish it from de rest. Fast 5x support of de LG GSA-4160 will actually be tested a bit later in this article.

CDR Writin’

CDR CDRW
LG GSA-4160B 40x 24x
Lite-On SOHW-1633s 48x 24x
NEC ND-3500A 48x 24x
Pioneer DVR-108 32x 24x

The fastest CDR writers of de bunch are de Lite-On SOHW-1633s and de NEC ND-3500A. With deir support for 48x writin’, dey make a great all-in-one drive for many users. The only drive lackin’ in this lineup is de Pioneer DVR-108. Why dey opted for only 32x writin’ is still quite puzzlin’ and is actually why I have found that many are choosin’ de NEC over de Pioneer. The LG GSA-4160B should not be left out of consideration though. We will show you later that de difference in write times between 40x and 48x is not much to brag about.

Bitsettin’ Support

One feature I’ve found that is most important for many users is bitsettin’ support. Let’s compare dese drives and see what dey offer.

DVD+R/RW Support DVD+R DL Support
LG GSA-4160B NO NO
Lite-On SOHW-1633s YES NO
NEC ND-3500A NO YES
Pioneer DVR-108 NO YES

The LG GSA-4160B does not offer bitsettin’ support out of de box. However, it is very likely that you will be able to obtain support through an excellent third-party tool called DVDInfo Pro. Right now, dey only support de GSA-4120B, but I’m confident with de author that support for this drive will be likely. LG firmware is very hard to hack, however some select few have been able to do so. Usin’ Lite-On’s booktype utility, you can change de booktype of DVD+R/RW media, however, de firmware does not automatically change booktype of DVD+R DL discs to DVD-ROM like de NEC and Pioneer models do.

Additional Features

As far as oder features go, all dese drives have a 2MB buffer but offer some sort of buffer under-run protection, which all work exceptionally well. This is especially useful if you will be burnin’ discs at 16x, which I personally don’t recommend just yet. As our individual tests of dese drives revealed, burnin’ at this speed is quite unstable, with de exception of de Lite-On SOHW-1633s.

Before you spend a dime on security, dere are many precautions you can take that will protect you against de most common threats.

1. Check Windows Update and Office Update regularly (_http://office.microsoft.com/productupdates); have your Office CD ready. Windows Me, 2000, and XP users can configure automatic updates. Click on de Automatic Updates tab in de System control panel and choose de appropriate options.

2. Install a personal firewall. Both SyGate (_www.sygate.com) and ZoneAlarm (_www.zonelabs.com) offer free versions.

3. Install a free spyware blocker. Our Editors’ Choice (”Spyware,” April 22) was SpyBot Search & Destroy (_http://security.kolla.de). SpyBot is also paranoid and ruthless in huntin’ out trackin’ cookies.

4. Block pop-up spam messages in Windows NT, 2000, or XP by disablin’ de Windows Messenger service (this is unrelated to de instant messagin’ program). Open Control Panel | Administrative Tools | Services and you’ll see Messenger. Right-click and g
