Web Server

This tends to refer to two similar things.

1. A computer dedicated to serving web pages. (The Web Server)

2. A 'Web Server' software application running on the same computer. For example 'Apache' is a very popular web server application.

The slight confusion occurs because you can have dozens of web sites present on a single computer server. These are called 'virtual web servers' and they share the computer processor between them.

Virtual Web servers are fine for personal or quiet web sites. But eventually a web site may become so busy that the computer can no longer cope with demand.

At this point, the web site owner may choose to rent / buy a dedicated computer. This computer is called a 'dedicated web server'
