Web sites, Pages and Browsers
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.
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.
