Web sites, Pages and Browsers

Web sites are hosted on computers called Web Servers. These machines will send a Web Page to your Browser when requested.


There a lot of different web browsers available, such as Firefox, Internet explorer, Safari. They all do the same job, to display a web page from a web server.

http

all Web page has an address (URL) that starts with http

This is very important because it is what brings the World Wide Web together. The http is a communication standard, or mostly known as a 'protocol'. If two computers were to use the same 'protocol', then they can share information between them. The World Wide Web uses the http protocol.
