What is a web server?
Web servers are the computers that actually run web sites. The term "web server" also refers to the piece of software that runs on those computers, accepting HTTP connections from web browsers and delivering web pages and other files to them, as well as processing form submissions. The most common web server software is Apache, followed by Microsoft Internet Information server; many, many other web server programs also exist. For more information about web servers and how to arrange to host for your own web pages, see the creating web sites section.
