A computer (A computer is a machine equipped with a processing unit allowing it…) on which an HTTP server operates is called a web server. The term “web server” can also refer to the HTTP server (the software) itself.

There are also HTTP servers which are application servers capable of doing HTTP server, like Roxen Where caudium (Originally based on Roxen 1.3, the Caudium software is a powerful, multithreaded HTTP server…).
