It was started in 1969, when the U.S. Depart

16、ment of Defence established a nationwide network to connect a handful of universities and contractors. The original idea was to increase computing capacity that could be shared by users in many locations and to find out what it would take for computer networks to survive a nuclear war or other disas

17、ter by providing multiple paths between users. People on the ARPNET (as this nationwide network was originally called) quickly discovered that they could exchange messages and conduct electronic “conferences” with distant colleagues for purposes that had nothing to do with the military industrial co

18、mplex. If somebody else had something interesting stored on their computer, it was a simple matter to obtain a copy (assuming the owner did not protect it).Over the years, additional networks joined which added access to more and more computers. The first international connections, to Norway and Eng

19、land, were added in 1973. Today thousands of networks and millions of computers are connected to the Internet. It is growing so quickly that nobody can say exactly how many users “On the Net”.The Internet is the largest repository of information which can provide very large network resources. The ne

21、ion, business, history, law, art, and entertainment, etc.The goal of your use of the Internet is exchanging messages or obtaining information. What you need to know is that you can exchange message with other computers on the Internet and use your computer as a remote terminal on distant computers.

22、But the internal details of the link are less important, as long as it works.

23、 interconnected system, but it uses just a handful of method to move data around.

25、ic mail (E-mail), or simply as mail. Mail permits network users to send textual messages to each other. Computers and networks handle delivering the mail, so that communicating mail users do not have to handle details of delivery, and do not have to be present at the same time or place.The simplest

26、way to access a file on another host is to copy it across the network to your local host. FTP can do this.Presently, a user with an account on any Internet machine can establish a live connection to any other machine on the Net from the terminal in his own office or laboratory. It is only necessary

27、to use the Unix command that sets up a remote terminal connection (Telnet), followed by the address of the distant machine.Before you can use the Internet, you must choose a way to move data between the Internet and your PC.
