The Internet is a medium for digital communication and it is expanding rapidly. It allows you see pictures, read text, view movies, type messages in real time, hear sounds, see and talk to others, and more.
The Internet was first “invented” during the “Cold War” when the USA was frightened that the Russians would bomb the Pentagon and destroy all of their confidential files. So the Pentagon began putting their files at universities around Washington and other States closer to the Pentagon. Then came the problem of how to get to these files and from this the Internet was born.
How does the Internet work?
Information exchanged by computers over the Internet is in digital format through
the use of a modem, a computer and an Internet Service Provider.
A vast number of computers make up the Internet.
The Internet is made up of a vast number of computers linked to each other,
mostly over telephone lines, but also by fibre optics, microwaves and even satellites.
The World Wide Web is just part of the Internet.
Although the terms World Wide Web and Internet are often used interchangeably,
the World Wide Web is only one part of what makes up the Internet. Other parts
include gopher and Usenet.
The World Wide Web (WWW) is probably the part of the Internet you're most familiar with and would use the most.
