In order to let other people see your web site, it must be placed on a web server. This is called 'hosting' a web site.

If you connect a web server to a local or private network then only people connected directly to that network can see it. In this case it is called an Intranet web site.

Companies use Intranet web sites to provide and share information amongst employees. For example, as a pupil of your school you can probably see the school intranet via a web browser but no one outside the school can see it.

Most public web sites are connected to the Internet where anyone can see them.

A web server is made up of two things

  • A computer.
  • Running on the computer, is a piece of software called the "web server software"

What is a web serverA computer running the web server software becomes a working web server

The web site is loaded in a directory on the server's hard disk. Then, whenever a request is made to view a web page from the site, the server finds it on the hard disk and sends a copy to the computer that made the request.

The 'World Wide Web' is made up of millions of web servers, each connected to the Internet.

In order to view a web page, the requesting computer must be running another piece of software called the web browser. There are many types of web browsers.
