INTERNET 101
Everything You Need to Know About the Internet (Almost)
 
The Internet

Whether you're new to the Internet, or consider yourself to be fairly experienced, I think you'll enjoy this informal guide.

It's not a comprehensive Internet overview, but if you are familiar with the information on this page, you'll find surfing the World Wide Web, sending email, and even exploring newsgroups far more enjoyable.
 

Even if you consider yourself an advanced Internet user, I'll bet there are a few tidbits of information here you didn't know - or had forgotten, so take a few minutes, scroll on down, and check it out.

Take your time.  Enjoy!

And tell a friend!

A BRIEF HISTORY OF THE INTERNET

Toward the end of the 1960's, the U.S. Department of Defense was searching for ways to safeguard communications from nuclear attack.  Until that time, communications systems were rather like a string of Christmas tree lights.  If one "light" went out, so did all the subsequent lights - and there went your communications link.  So instead of having a single "control center," they distributed the various communication links across a network.  The network was so designed that if any portion of it went down, that portion would be isolated from the rest of the network, which remained interconnected without it.  Instead of a "hub," with all stations connected to the center, the new system was more like a "grid" - or "web." 

Eventually a new set of technical standards arose, called "TCP/IP" (Transmission Control Protocol/Internet Protocol).  This permitted a unified interconnection of different types of computers into this new "inter-net."  Soon others began to use the new system, starting with universities and other institutions, and then - look out - businesses.  Since each computer on the network was connected independently of the others, no real centralized control of the Internet emerged.

As you read this, the Internet connects almost 100 million people in the U.S. and millions more around the rest of the world.  And yet the explosive rise of the Internet is still many years from peaking.  In the very near future, huge numbers of everyday appliances - from refrigerators and toasters to automobiles and aircraft - will all intercommunicate using Internet technology. 

According to Bill Gates, founder of computer software giant Microsoft, and author of the best-seller The Road Ahead, this communications revolution will make the personal computer revolution pale by comparison.  Hard to imagine, no?  But, so far his predictions have all been right on the money.

World Wide WebThe visual, multi-media part of the Internet you may be used to has come to be called "The World Wide Web" - or "The Web."  You explore, or browse, the various sites on the Web with special software called a "browser."  Two very popular browsers are Netscape (formerly Netscape) and Internet Explorer.  Either of these browsers will help you maximize your Internet "surfing" experience. 

A newer browser I particularly like is called Mozilla Firefox (I use this one more than Internet Explorer these days).  Netscape and Firefox are both based on the same Mozilla "engine".

All these browsers are 100% FREE.

Where Did the Web Come From?

No, Al Gore did not invent the Internet.  The World Wide Web was begun at CERN, a particle physics laboratory in Geneva, Switzerland in 1989. Tim Berners-Lee invented the HyperText Markup Language (HTML) which enabled linking from page to page, and set the Web apart from other networked computer files. By late 1990, CERN had developed a Web server and a text only browser. Originally envisioned as a text-only feature, hypertext swiftly began to allow graphics on the Web and access to applications in virtually any medium. By early 1993 there were 50 Web servers in existence and rudimentary, but graphical browser software had been made available for the Macintosh. By February 1993 the Web was accounting for 0.1 per cent of all Internet traffic.

The Mosaic Revolution

Developed in 1992 at the National Center for Supercomputing Applications (NCSA) at the University of Illinois by a team headed by Marc Andreessen, Mosaic was the first truly graphical, easy to use interface for the Web which allowed the display of colors, pictures, graphics, even sound and videos. Andreessen went on to participate in the formation of Netscape, with Jim Clark, the former CEO of Silicon Graphics, and its browser, the Navigator, quickly became the standard of the industry.

Wildfire Growth

"The Web is moving from first appearing as a neat application to being the underlying information space in which we all communicate, learn, compute and do business," said its creator, CERN's Tim Berners-Lee. The Web seemed to burst into the national consciousness overnight -- suddenly Web page addresses became commonplace in print and TV ads and having a personal home page was almost as necessary as a cell phone to signal being current. Microsoft Corporation was quick to join the fray with their browser, Internet Explorer, and the competition between them and Netscape has continued to fuel growth because of the rapid improvements in browsers that keep occurring as they try to "one-up" each other.

Internet GrowthAfter the entry of businesses into the system in the late 1980's, the Internet - and especially the World Wide Web - grew to very large numbers, carrying ever-increasing amounts of users, transmitting tremendous quantities of information.  Soon people of all walks were depending on the Internet to help them manage information and communication in their daily lives and businesses.  To deal with the demand for access to the Internet, companies arose that offered connection services through dial-up modems, devices that use regular voice telephone lines to connect to the Internet.  These companies are called Internet Service Providers, or "ISPs." 

That single change let the genie out of the bottle, so to speak, and the Internet exploded.

You see information on the Web as "pages" that you can view with your browser.  Web pages can contain any combination of text, pictures (even animated ones), sound and video.  When companies, universities, non-profit organizations, the military, even everyday people, create a series of web pages all linked together in one location, that's called a "web site."  Usually the first page is called the "home page," and acts as a kind of doorway, or table of contents, to the web site as a whole.

Web pages are written in a special language, called "HyperText Markup Language, or "HTML."  In fact, a web page is really just a file on a computer that contains text written in HTML.  All the artwork, pictures, sound, video, etc. that you see on a web page are not actually "on" the page, but rather they are pointed to by references in the page's HTML text.  You can see this page's HTML text by clicking on your browser's View menu at the top of this screen.  (In Mozilla Firefox or Netscape, click on View, then Page Source.  If you're using Microsoft Internet Explorer, click on View, then Source.   If you're not using one of these popular browsers - why not?).

section separator

Web pages are labeled with a unique identifier called a Uniform Resource Locator, or "URL" (still any doubt about the military's involvement in the development of the Internet?).  The URL tells the Internet how to take a visitor to a particular web page.  In fact, we call URLs "addresses."  You simply type in the URL in the area in your browser that asks for an "Address" or "Location" and press the Enter key on your keyboard.

URLs begin with "http://" - "HyperText Transfer Protocol."  Since every URL starts with "http://", any decent browser inserts that for you automatically, so all you need to concern yourself with is the "meat" of the address, which actually tells the Internet which computer - or "server" - the web page is located on.  This site, for example, has an address of http://www.shaunfurlong.com.   The most common beginning of an address is "www", which tells the Internet you're looking for an address on the World Wide Web - obviously the most popular place to go.  Similarly, most URL addresses end with ".com", which stands for "company."

Although most URLs will end in .com, there are many other types of address "suffixes."  Here is a list of the most common, and what they stand for:

.net computer network
.org nonprofit organization
.info information
.biz business
.ws  website (seriously!)
.tv television
.gov government
.mil military
.edu educational (colleges, universities, etc.)
.ca Canada
.uk United Kingdom
.jp  Japan

(country suffixes are optional - a site based in Japan may still end in .com) 

And more suffixes are on the way.  

When typing URLs, as with most things computer-related, you must be sure to type the address exactly as given, and especially watch out for spaces.  There are none in URLs.  It is also important to distinguish between a "/" ("forward slash or "slash") - and a "\" ("back slash").  The easiest way to remember them on a standard 101 style keyboard is that a forward slash shares the question mark key, and the back slash is near the back key (laptops and non-101 keyboards don't count - these keys could be anywhere on those).

section separator

When you see an address underlined in a web page, or elsewhere in your computer system like this:  www.shaunfurlong.com, that means it's a "hyperlink" - or "link."  If you click once on a link with your mouse, it will automatically take you to its web page, without you having to type out the address in your browser.  Links can be pictures, too.  You can always spot a link because when you move your mouse pointer over it, the pointer turns into a little pointing hand, and often the link will change color, too.  Try it with the links on this page.

Most browsers also assume that the "www" part of the address should be there even if you don't type it.  Many also do the same with the ".com" part of the address.  So instead of typing:

http://www.shaunfurlong.com

you could simply type

shaunfurlong

...and you may end up in the same place.  Or your browser may automatically send you to a search engine to look it up.  Try it (you can use your browser's "Back" key to return here to this page).  Remember, these are assumed "defaults."  If the address doesn't begin with "www" or end with ".com", you must type in the address exactly as it's given to you.

Probably the easiest way to begin surfing the Internet is by using the links provided to you by your Internet Service Provider (ISP).  Usually, ISPs have their own start page (also called "portal pages"), peppered with links to interesting places.  Yahoo! provides a very good customizable start page at, you guessed it, www.yahoo.com.  Just go there and click on My Yahoo!  Most search engines provide good start pages (more on search engines in a moment). 

Searching the InternetVery often you can customize these pages to your own liking, so that topics that don't interest you, e.g. "sports", can be removed from view.  You can even go there (right now, if you like!) and set your browser to bring you to that web site (or anywhere, for that matter) when it starts up.  Every time you run your browser, it will then automatically take you to your chosen web site (your browser's Help feature can help you here.  Browsers usually refer to such an "auto-start" feature as setting your "home" page, an unfortunately confusing term that shouldn't be confused with a web site home page as defined above).  If you received your browser software on a CD from your ISP (e.g. EarthLink, AOL), when you installed your browser it probably set itself to start at their start page (it's only fair, isn't it?).

section separator

Search engines and directories are web sites that house special software to look for web sites based on your search criteria, usually a few "keywords."  Some very popular search engine and directory web sites are, in no particular order:

These are by no means all the search engines and directories out there; there are actually thousands.   Although they all work pretty much the same, you will find that each has its own distinct "personality."  Choose the one you like the best or feel free to bounce back and forth between them. 

Can't decide on a favorite?  There are search engines that actually combine other search engines. Called "meta search engines", DogPile and metacrawler are two good ones that come to mind.

The difference between search engines and directories is that search engines constantly visit web sites on the Internet using special "robot" software called "spiders" or "crawlers", and catalog their findings.  Because they run automatically and index so many web pages, search engines may often find information not listed in directories.  Directories, such as Yahoo!, are administrated by people, not robots.  Sites are submitted to directories, where they are assigned to an appropriate category or categories.  Because they are manned by decision-making humans, directories often deliver a better or faster payoff.

Using search engines is easy.  All you do is type in your keyword(s) and click on the Search or Go button (Of course, in DogPile it's the Fetch button).  Complete help and instructions are right there on each search engine's home page.  Some web sites are better found by one search engine than another.  Like anything else, the more you use search engines and directories, the better you'll get at it.  But because they are essential for you to maximize your use of the Internet, take some time and get used to them.

section separator

You can store web site addresses in your browser so they're easy to return to later.  Microsoft Internet Explorer calls these remembered web sites "Favorites", while Firefox and Netscape calls them "Bookmarks."  But they both operate essentially the same way.  While you're visiting a web page you want to store for later use, just click on the Favorites or Bookmarks icon at the top of your browser screen, and then click on Add to Favorites or Add Bookmark.  Your Bookmarks and Favorites can be organized into folders, just as you would organize files in your computer.

Some web pages contain links that will automatically open your browser's Add to Favorites or Add Bookmark feature when you click on them.  In fact, if you want to bookmark this page, just click here to see how a Favorites link works (Firefox and Netscape users, type Ctrl D on your keyboard).

EmailOne of the most powerful benefits of being connected to the Internet is the use of electronic mail, or "email."  Once you get used to communicating via email, you will almost certainly not want to do without it.  You can send messages just about instantly to anyone else who has an email address and email software, and they can respond back to you with ease.  You can then respond to their response, and so on.  You can also forward messages to any number of email recipients, who can then forward your message or respond directly to you. 

And how much does this wonderful service cost?  Believe it or not, it's included in the monthly Internet access fee you pay your Internet Service Provider!  What's more, almost all browsers include their own email software when they are installed on your computer. So while email is not technically free, you have already paid for it!

You can start your email programs in different methods.  The most popular way is to click on your browser's Mail icon.  But you can also start your email programs on their own by clicking the Windows Start button (located in the lower left-hand corner of your display), then Programs and then clicking on the email program name (Microsoft Internet Explorer uses Outlook Express - or possibly Outlook if you have MS Office - and Netscape uses Messenger).

Using your email software to send an email message is a simple, five-step process:

  1. Run your email program

  2. Compose (create) a message

  3. Send the message to your Outbox

  4. Connect to the Internet via your Internet Service Provider (ISP), if you are not already connected.

  5. Transmit the message.

It is worth mentioning here that there is a very common misunderstanding about the difference between steps 3 and 5.  This creates a lot of unnecessary confusion when learning to use email, so let's take a moment to clear it up. 

The problem arises because most email programs refer to steps 3 and 4 with the same term: "Send."   It is therefore not at all unusual (in fact it's fairly common), for email novices to create a message, and then "send" it, without the message ever leaving their computers!

Typically they will complain, "I clicked on the "Send" button.  How come nobody got my messages?"  The answer is: Because the message you created and "sent" (step 3) is still sitting in your Outbox, waiting to be transmitted (step 5).  

So why doesn't the email software just send and transmit the message simultaneously when we click on the "Send" button?  Because many people still connect to the Internet via a dial-up modem.  This two-stage "send" method enables us to compose any number of email messages before connecting to the Internet, store them in our Outbox, and then, later, when we're connected, transmit ("send") them to our ISP's email server (computer).  Otherwise, we would either have to already be connected every time we sent an email message, or get connected in order to send one.  The two-step "send" and "transmit" method permits us to connect when convenient, not every time we're composing an email message.

If you are using a high bandwidth connection, e.g., DSL of cable, then Send and Transmit are usually automatically combined, because you are usually always connected ton the Internet.

It is also worth mentioning here that most email software also retrieves incoming messages to you at the same time it transmits your outgoing messages. 

In any case, if you are not connected to the Internet, and you ask your email software to transmit/receive messages, you will more than likely be prompted to connect via your dial-up modem at that time.

All you need now to send an email message is the email address of the person you're emailing.  Email addressed have three parts: username, @ symbol, and hostname:

Username

@ symbol ("at")

Hostname

Examples:

stevesmith
smith
shaun
spunky

@
@
@
@

earthlink.net
earthlink.net
shaunfurlong.com
happynet.com

Username: The name the email user selected when they signed up for email.
The @ symbol ("at"): Self-explanatory.
Hostname: The name of the server (computer) where the user's email account resides.

When email is sent from one person to another, it is actually copied onto an email server, a powerful computer that stores the messages in virtual "email boxes" until their owners retrieve them.  The time it takes an email message to move from your ISP's email server to your recipient's ISP's email server will depend on the efficiency of those ISPs.

The world of email has its own set of rules and regulations.  The rules are generally optional and fall under the heading of "netiquette" - the term used for etiquette on the net (not a term invented by the military).  Regulations are compulsory and are created by the FCC and your ISP.  If you follow the rules of proper "netiquette," you will probably never run afoul of the cyber cops.

Email communication is unique and there are some special rules that apply here that really don't apply anywhere else.  Here are three biggies:

  1. Avoid using all capital letters in any message unless you absolutely intend to.  Caps indicate YELLING.

  2. Be careful how you phrase things.  Without the voice-to-voice component, you can be easily misunderstood.

  3. Avoid sending email to anybody who may not want it (it's called "spam"), especially for commercial purposes. 

Let's say you've received the following email message:

Hi, Sam!
Are we going to the movies today?
I hear "You Have Mail" is great!
Let me know what theater you want to go to and I'll get the show times.
Mary

You now have the option of replying to the message automatically.  You do this by clicking on the Reply button at the top of your email window.  This will open a new message window for you that includes the original message, indented with an angle bracket (>), like so:

>Hi, Sam!
>Are we going to the movies today?
>I hear "You Have Mail" is great!
>Let me know what theater you want to go to and I'll get the show times.
>Mary

There are three basic ways you can type in your reply:

1. Simply write your reply above the indented original message, like this:

Mary:
Sounds good.  How about the early afternoon at The Eyeball Burner Express 30-Plex?
Get back to me with the time and I'll meet you at the theater.
Sam

>Hi, Sam!
>Are we going to the movies today?
>I hear "You Have Mail" is great!
>Let me know what theater you want to go to and what show time is best for you.
>Mary

2. Write your reply below the original message, like so:

>Hi, Sam!
>Are we going to the movies today?
>I hear "You Have Mail" is great!
>Let me know what theater you want to go to and what show time is best for you.
>Mary

Mary:
Sounds good.  How about the early afternoon at The Eyeball Burner Express 30-Plex?
Get back to me with the time and I'll meet you at the theater.
Sam

3. Intersperse your reply after each paragraph or point in the original message:

>Hi, Sam!
>Are we going to the movies today?

Sounds good.

>I hear "You Have Mail" is great!
>Let me know what theater you want to go to and what show time is best for you.
>Mary

How about the early afternoon at The Eyeball Burner Express 30-Plex?
Get back to me with the time and I'll meet you at the theater.
Sam

You can always use the first method, but you may want to use the second method if there has been any appreciable delay, so you can bring your correspondent up to speed.  And the third method is best used when you have a long message you want to respond to point by point.

When the message is responded to by your recipient, an additional angle bracket is automatically added to each previous response in order to keep the order straight.  If you were using method 1 above, your final reply would look like this, with the messages sequenced from bottom to top:

The Eyeball Burner Express 30-Plex it is!  The show starts at 1:40pm.
I'll see you there!
Sam

>Mary:
>Sounds good.  How about the early afternoon at The Eyeball Burner Express 30-Plex?
>Get back to me with the time and I'll meet you at the theater.
>Sam

>>Hi, Sam!
>>Are we going to the movies today?
>>I hear "You Have Mail" is great!
>>Let me know what theater you want to go to and what show time is best for you.
>>Mary

Your email program has lots of options, and you'll get to understand them best by just jumping in and using your email.  We won't even try to cover everything here.

By the way...

Posting unsolicited email messages (usually promoting a business) is called "spamming" and is probably the single biggest offense you can commit on the Internet after hacking (breaking into someone else's computer).  So...

No spam!
DO NOT SPAM!

Yes, I'm yelling!

An email "attachment" is a file that "piggy-backs" on your email message.   This way you can send somebody a word processing or text document, a picture file, a sound file - pretty much any file in your computer - via email.

At the top of the new message window in your email software is a small icon of a paper clip.  All you have to do is click on that icon, navigate to the file you want to send, and double-click on it.  An icon representing the file will appear in your document.  When you send your email message, the file you have attached will ride along with it.

When you receive a document that has an attachment, a small paper clip icon will appear next to it in your inbox.  All you have to do is open the document and you will see the icon of the attachment.  You now have three choices.

  1. Save the attachment file in your computer.  Right-click on it and select Save As...  Then navigate to the appropriate folder in your system and click on the Save button.

  2. Open the attachment file right now.  Just double-click on the file's icon and follow the prompts (this will vary depending on what type of file you're opening).

  3. Do nothing.  Maybe the attachment is not important to you.  Just close your email message window as usual and move on.

One of the most popular attachments to send are web pages and web links.  While you're surfing the Internet, you will come across a page you just know one of your email associates will want to visit.  You can send them this information from your browser without even opening your email software. 

To send a web page or link by email, just go to that page using your web browser.  In Microsoft Internet Explorer, click on File, then move your mouse pointer to Send..., then click on Page by Email... or Link by Email...  The browser will open your email new message window and automatically include the page or the link for you.  All you have to do is tell it which addresses you want to send the web information to.

With Netscape, the procedure for sending web pages is identical.  However, for sending a web link, you must do it manually.  (Copy the web page URL address from the Location field and paste it into an email message.  This is easiest accomplished by highlighting the URL in the Location field and pressing Crtl C.   Then open an email new message window as you normally would, type in the address(es), type in the subject and paste the URL into the message are by typing Ctrl V).

Note that when you are sending a web page, some or all of the page's artwork may not accompany the file.  The recipient may see only text and a great deal of "holes" where the images were.

Links will appear as underlined text in an email document.  Web pages will appear as attachment icons.

Keep your attachment files as small in size as you can, under 100KB if possible.  Not only will larger files take a long time to download to your email recipient (making them wait for it), most ISPs limit the size of their customers' email boxes to somewhere around 2MB.  If you cause someone's email box to fill up, he or she will not be able to receive email until it's emptied (downloaded) again.  This will not help you win friends.  A good rule to live by is to ask first whenever you're going to send someone an email message larger than about 100KB.

There is a part of the Internet, "Usenet", that has on-line discussion groups, called "newsgroups."  A newsgroup is very much like a bulletin board, where people post information by topic.  When somebody posts a message, anyone visiting the newsgroup can post a follow up message, and then another person can follow up to either message, and so on.  Taken together, a newsgroup message and all of its follow up messages are called a "thread."

In the same way your browser included software for email, it also includes a program for you to access newsgroups.   Internet Explorer contains a news reader inside its email program called Outlook Express.  From Outlook Express's menu, just select Go, then News.  Or you can just select the Mail icon from the Internet Explorer browser, then select News.

Netscape's news program is called Collabra, and it is also accessible through the Netscape browser.

Newsgroups are usually very specific in terms of the topics they each cover.  There is probably a newsgroup for anything you can think of.  For the most part, like much of the Internet, newsgroups are not regulated.  Some of the topics can be offensive, so be look out.

Like email, newsgroups allow you to submit (post) your message anytime.  Unlike email, however, you must log on to the specific group you want to communicate with, and use a reader to see the messages posted there, and everyone will see everything that's been posted.

Google has a website that specializes in information about newsgroups.  Take a few minutes to visit this site, especially if you're new to newsgroups.  You can search for newsgroup information at groups.google.com.

Newsgroups permit you to be heard by a large group of people, and for them to contact you.  But there are a few things you should know about newsgroup netiquette:

The biggest offense you can commit on a newsgroup (and the most common) is to post something that is off topic - in other words, something that has nothing to do with the topic of that particular newsgroup.  Commercial messages that attempt to take advantage of the vast number of potential customers gathering in a newsgroup are even worse.  

As with email, posting lots of unsolicited newsgroup messages (usually promoting a business) is called "spamming" and is probably the single biggest offense you can commit on the Internet after hacking (breaking into someone else's computer).  So...


DO NOT SPAM!

Yes, I'm yelling again.  It's important.

Posting off-topic messages and spamming is more than likely going to get somebody angry enough to send nasty messages back to you.  Sending nasty messages is called "flaming" and it's no fun, especially if you feel compelled to respond and they respond to your response and others join in and you end up in an all out "flame war."  You may also be reported to your Internet Service Provider, who, in most cases, will shut you off almost immediately.  When it comes to spam, ISPs usually adopt a "shoot first and ask questions later" approach.

Here are some good rules of newsgroup Netiquette:

  1. Lurk first:  Spend time "lurking," or watching, a newsgroup before you post for the first time.  Every group has its own structure.  The more you watch, the more you'll be able to effectively contribute when you speak.
      

  2. Know the FAQs:  Before asking a question in a newsgroup, see if you can find an answer in that group's "Frequently Asked Questions" (FAQ for short).  FAQs contain basic information on the group, its purpose, and common questions they'd rather not have asked again.  FAQs were created to cut down on the questions that new users (called "newbies") often post in newsgroups.  There may be more than one FAQ for a particular group, especially if it's populated by people with opposing views.  If you can't find an FAQ, go ahead and ask your question.
      

  3. Be Prepared:  No matter how careful you are, you may eventually get flamed - so get used to the idea.  You are bound to step on someone's toes and make someone upset, and you'll probably get a rude note in your email box or a nasty post about you in the newsgroup.  The best way to respond to a flame: don't respond at all.
      

  4. Don't Flame:  If you see an off-topic or silly posting by a new user, be polite.  Send the user a note by email explaining what he or she did wrong.  Don't flame.
      

  5. Follow the thread:  Only post a follow up message to a thread (a series of messages on a topic) if your message is directly related.  If not, post a new message and start a new thread.
      

  6. Don't post copyrighted or private information:  There is a legal issue here, but there is also an ethical one.  Don't post the copyrighted or private information of others without their permission.
      

  7. No "me toos":  Don't waste resources and time posting "me too" responses.  They take up space and add nothing to the thread of conversation.  But feel free to send support via an email.  Everyone appreciates acknowledgment, and you could make a fast friend.
      

  8. Be nice:  Always stay calm.  Be polite.  Be cordial no matter how obnoxious the other poster is.

You can really apply these rules to all Internet activity.

The Structure of Newsgroup Posts

Newsgroup names tell you what the purpose of the newsgroup is.  Here are some examples:

alt.fan.letterman  -  David Letterman fans
comp.robotics.research  -  computer robotics research
misc.writing  -  writing
rec.sport.unicycling  -  unicycling
soc.culture.welsh  -  Welsh culture

Most newsgroups are classified into standard sets, which are defined by the first word (or abbreviation) before the first period in the name.  These are the major newsgroup sets:

alt.  -  alternative newsgroups (by far, the largest of all the newsgroup sets
comp. - computer
misc. - miscellaneous
rec. - recreation
sci. - science
soc. - society and culture

Following the name of the set are one or more words separated by periods, providing greater detail about the newsgroup.  For example, the newsgroup devoted to network administration for the computer operating system Windows NT looks like this:

comp.os.mswindows.nt.admin.networking

Generally speaking, you don't have to know much about this naming protocol because your system's news reader will find any portion of a newsgroup name.  For example, if you type in the word "collie", your news reader might display:

alt.animals.collie.open-forum
alt.animals.dogs.collie.free-speak
alt.animals.dogs.collie.open-forum

The first and third are probably redundant - two separate newsgroups discussing the same topic - a fairly common occurrence.

As with all things, the best way to learn about newsgroups is to try them out.  Run your system's news software (e.g. Outlook Express) and find out how to go to the newsgroups.  Search for some topics of interest and see what shows up.  Go to those newsgroups and see what's there.  After you've lurked for awhile in a few newsgroups, and you have a feel for what goes on in each one, go ahead and post a message - or a reply (if you have something even vaguely of interest to contribute - that's why I suggested "topics of interest").  

Go back into the newsgroup periodically and see how long it takes your post to show up.  See if anyone posts a reply back to your post.  

Have fun!
