Internet

The best way to think of the Internet, or Net as it is often called, is a vast global network of networks connecting computers across the world. At present, more than 33 million people use 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.

The Net was dreamt up in the late 1960s by the US Defense Department's Advanced Research Projects Agency which decided that it needed a means by which messages could be sent and received even if phone lines were inoperative. In 1969, there was a network of just four computers. By 1972 the number had risen to 40. About this time the idea of electronic mailbox was born. By 1984 the Internet began to develop into the form we know it today.

The Internet can be divided into five broad areas.

Electronic mail, which is much faster than traditional mail. Any­thing that can be digitized (converted into digital form) - pictures, sound, video - can be sent, retrieved, and printed at the other end.

Information sites. This is perhaps the fastest growing area of the Internet as more and more people put their own information pages on line. Computers process vast amounts of information very fast, by specifying a key word 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, usually referred to as WWW or 3W, is a vast network of information databases that feature text, sound, and even video clips. On the WWW you can go on a tour of a museum or exhibition, see the latest images from outer space, go shopping, and get travel information on hotels and holidays.

Usenet is a collection of newsgroups covering any topic. 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 programs allow you to use your personal computer to ac­cess a powerful mainframe computer.
