How Does the Web Work?

website

A collection of linked web pages (plus their associated resources) that share a unique domain name.

web server

A computer that hosts one or more websites. All the web pages and their supporting files are available on that computer. The web server will send any web page from the website it is hosting to any user's browser, per user request.

web browser

A software application that retrieves and displays web pages.

search engine

A special kind of website that helps users find web pages from other websites. Search engines are normally accessed through a web browser (by typing directly into the address bar) or through a web page (by accessing the web site).

web page

An HTML document which can be displayed by a web browser. Web pages can each be found at a unique location (URL).
