___________________
A research team in the USA first had the idea of linking computers together in the 1960s. They wanted computers in universities, research departments and the military to communicate with each other and share information. At that time, computers were bigger than fridges. People could not move them easily. Computers were also complicated and difficult to use.
Slowly, more and more people started to link their computers together. Then businessmen started to use the Internet too. Today, people all over the world are using the Internet.___________________
There is a wide range of services on the Internet. For example, we can use it to communicate with other people. The most popular way to communicate is through electronic mail, or “e-mail”. We can also use services such as MSN messenger or Skype. We can use these services to send instant messages to people near or far away.
The Internet allows us to use the World Wide Web (also known as WWW or the Web). The Web is many connected pages of information. We can use the Web to read news and learn about our favourite sports stars or singers.
