The internet , in physical terms, is a vast global network made up from many thousands of computer networks and individual computers. The internet “works” because these computers can all speak the same language, called TCP/IP (which stands for Transmission Control Protocol/Internet Protocol).
For most people, the internet is the same thing as the World Wide Web and all the web addresses that appear everywhere these days – on product packaging, at the end of TV shows, and on junk mail. But there is more to the internet than the web.
There are vast networks of computers devoted to newsgroups, bulletin boards and discussion groups, and thousands of servers across the world are devoted to online “chat” areas.
But the web is the part of the internet that has seen such a rapid explosion in popularity and ease-of-use.
