What is the Internet
The Internet is a collection of computers around the globe all connected together in a vast network with the ability to exchange information. This network was originally created to allow government computers to exchange vital information even after a nuclear attack disrupted most normal communications. It then expanded to the world wide academic fraternity of universities and research institutes and finally to the rest of the world. Connecting your computer to this network allows you to tap (and contribute) to this stream of information.
Each computer on the Internet has an address -- just like your mailing address -- that identifies it to all other computers on the 'Net. This address is its "URL" (Uniform Resource Locator) -- it identifies both the computer and the protocol (type of connection) used with it. An example would be "http://www.company.com" -- this identifies a computer called "www" at "company" in the "com" (COMmercial) domain (the top-level or "country" part of the address) and using the "http" (HyperText Transfer Protocol -- the World Wide Web) protocol.
Some other protocols would be: "ftp" for File Transfer Protocol; "gopher" for an older way of getting (mostly) text based information; and "mailto" for electronic mail. There are others that you can find out about once you're on-line.
How to Connect Your Computer to the Internet
Most new computers today already come with the tools you need to connect to the Internet already installed. All you need is to get a local "ISP" (Internet Services Provider) and type in the information he gives you into the Internet configuration application on your computer.
For older computers the ISP can either give you a "disk" (or CD-ROM) that will configure the computer and install the basic tools needed to get on the 'Net or give you the information needed to get and install those tools. You need three things: a "TCP/IP stack" (Transmission Control Protocol/Internet Protocol -- the basic driver that "speaks" Internet); an "API" (Application Programming Interface -- the connection between the driver and the applications); and the Internet applications themselves. Of course you will also need a "modem" (MOdulator- DEModulator -- it transmits digital information over the 'phone lines)and a connection to the telephone service to physically connect to the 'Net.
Each computer platform (Windows, Macintosh, Linux, etc.) needs a different set of these tools so I won't go into any detail here, you'll find the information needed for each platform from your local user group or computer guru. Installation and configuration is also different for each platform so follow the instructions given you by your ISP.
Some of the applications you'll need will be a "dialer" (a way to dial and connect the modem with the ISP's computer usually supplied by the ISP) and a "browser" that allows you to "surf" the World Wide Web and which usually contains an "e-mail" application and a "news reader" application in addition to "ftp" for transferring files.
Getting Information On-line
There are many ways of getting information on the Internet.
The World Wide Web is one of the most popular because of it's "multimedia" (text, images, sound and animation) aspects. Since the Web's graphic interface was developed in 1993 the Web has become everyone's idea of what the "Information Superhighway" is.
One fundamental concept of the Web is hyper links.
The ability to jump to another page of information by clicking on a "link" on the current page is what hyper links are about. Links on this page will be a different color than the rest of the text and should be underlined. There are now tens of thousands of web sites on-line with millions of pages of information world-wide.
The "browser" is your doorway to the Web.
What your browser looks like, the features it has, and how you use it depends on your computer's operating system and the browser you use. All browsers allow you to navigate the Web by either pointing and clicking with your mouse on hyper links or using the keyboard to navigate. There are text-only browsers that allow almost any platform to use the Web, although they miss the multimedia parts of the Web, but most people will use a graphical browser to gain the full effect of the Web.
With so much information on the Web, finding what you want could be a
problem. Fortunately, most browsers come setup with a "Start Page"
and a "Search Page" just a click away to help you get there. These
pages give you an idea of what's out there and allows you to search for
the information you want in most of the popular search engines. Even so,
there is no ultimate search tool for the Web, though
Yahoo
comes close and you'll eventually learn which engine gets the kind and
type of information you want by using them all.
Most browsers have a "bookmark" feature that allows you to place URLs of pages you've found interesting in a structured set of folders and links just a click away -- your personal index of Web sites. You can also create a custom start page with the information you most frequently need either on your browsers home page or on one of the search engines home page.
If the Web wasn't enough for you there are also personal communications tools to get you in touch with everyone else on the Internet such as E-Mail, IRC, and News.
The Power of E-Mail, Conferencing & Support Groups
There are three major ways of communicating with other people on the
Internet, E-Mail, NEWS, and IRC. E-Mail is universally the Internet
service most people are most familiar with. It's basically the Internet
equivalent of regular "snail" mail from the post office. Most modern
browsers include an e-mail client and make it relatively easy to use
e-mail from them. To find someone's e-mail address look them up on the Web
using one of the popular white pages directory services like
http://www.four11.com
.
Usenet Newsgroups (also called "NEWS") are places in Cyberspace where you can join in thousands of bulletin board type discussions on any topic imaginable. Any Server on the Internet can host a Newsgroup There is no central Usenet authority. Each news server can decide which newsgroups it will carry and which, if any, it will host. No topic is off limits here and you may want to limit your child's access to newsgroups though one of the blocking services.
With the advent of modern browsers for the Web, you no longer need a
separate application to "read" newsgroup articles -- it's built-in
already. The trick is in finding the newsgroups that interest you. Ask
your ISP about the list of newsgroups it carries and remember that no one
carries them all. Understanding the "code" of newsgroups titles is
important to finding what you want so you might want to join
news:news.announce.newusers
and news:news.newusers.questions
first and then read the "FAQs" (Frequently Asked Questions) in
news:news.answers
to learn more about newsgroups.
Another service, "IRC" (Internet Relay Chat) is a live version of Usenet, like talking on a party- line telephone. There are a number of "channels" that come and go as created by the participants. A channel remains in use as long as at least one user is joined to it and the first person to create that channel is its "Operator" and controls that channel. This is another service requiring careful supervision if used by children due to the inherent anarchy of IRC.
You can find lists of publicly accessible IRC servers and clients and
additional information on IRC in the news:alt.irc
hierarchy newsgroups or on the web at
Yahoo
