4. Web sites, pages and browsers

web pageWeb sites are hosted on dedicated computers known as 'web servers'. These machines will send a web page to your browser when you request it.

There are many different browsers available, such as Chrome, Firefox, Internet Explorer, Opera, Safari and so on. But they all do the same job - namely to display a web page delivered from a web server.

Each web page has an address (URL) that starts with http: or https: for a secure page.

This is very important, as it is what binds the World Wide Web together. The http is a 'protocol', which is a fancy word for a communication standard. If two computers share the same 'protocol', then they can share information. The http protocol is the one used for the world wide web.

The internet is more than just the World Wide Web, and those other parts use different protocols. For example for exchanging files between internet computers use the 'ftp' protocol.
