Internet

The best way to think of the Internet, or Net as it is often called, is as a vast global network of networks connecting computers across the world. These networks range from government departments and industrial and educational communication systems down to the personal online service providers such as CompuSeve, Delphi, etc.

At present, more than 33 million people use the Internet and over three million com­puters worldwide are linked in. They use the Net for transferring data, playing games, so­cializing with other computer users, and sending e-mail (electronic mail).

The Internet can be divided into five broad areas:

Electronic mail

E-mail is much faster than traditional or snail mail because once the message is typed out, it arrives in the electronic mailbox of the recipient within minutes or seconds. Anything that can be digitized (pictures, sound, video) can be sent, retrieved, and printed at the other end. This is efficient, convenient, and saves trees!

Information sites

This is perhaps the fastest growing area of the Internet as more and more people put their own information pages on line. One thing that computers do very well is process vast amounts of information very fast, so, by specifying a key world or phrase, the computer can then search around the Net until it finds some matches. These information sites are usually stored on big computers that exist all over the world. The beauty of the Net is that you can access all of them from your home, using your own PC.

The World Wide Web

The World Wide Web, usually referred to as WWW or 3W, is a vast network of in­formation databases that feature text, visuals, sound, and even video clips. On the WWW you can do such things as go on a tour of a museum or art exhibition, see the latest images from outer space, go shopping, and get travel information on hotels and holidays. You can even view a hotel's facilities before deciding to book!

Usenet

Usenet is a collection of newsgroups covering any topic. Newsgroup allows users to participate in dialogues and conversations by subscribing free of charge. Each newsgroup consists of messages and information posted by other users. There are more than 10,000 newsgroups and they are popular with universities and businesses.

Telnet

Telnet programmes allow you to use your personal computer to access a powerful mainframe computer. If you are in academic, or just have a lot of number-crunching to do it can be useful and cost-effective.
