Below are some types of services provided by the internet;

www:

www is a system in which documents (called web pages) stored in special computers (web servers) can be accessed and viewed from any part of the world, by computers that are connected to the Internet. These web pages can be accessed and viewed using a special program called a ‘web browser’, for example, Internet Explorer, Netscape Navigator, Safari, Crazy, Mozilla, Opera, Bolt, Google Chrome, etc.

The web pages contain texts, graphics, animations, and videos as well as hypertext links. The links let users jump from one page to another. Web pages are specially formatted using a web page formatting program, called HTML, that supports links to other documents.
