Briefly explain the basic concepts of a web server and web hosting.

A web server is a WWW server that stores web documents and responds to requests made by web browsers. Some examples are Apache, IIS, Nginx, GWS, and Netsite.

A website is physically located on a web host. A group of linked web pages qualifies to be called a website only when hosted on a web server. When the user specifies the address of the website, the web pages are transmitted to the user's computer from the web host.
