APACHE (Introduction):

Apache is the world's most popular Web server (HTTP server). The original version of Apache was written for UNIX, but there are now versions that run under OS/2, Windows and other platforms.

The Apache Web server provides a full range of Web server features, including CGI, SSL, and virtual domains. Apache also supports plug-in modules for extensibility. Apache is reliable, free, and relatively easy to configure.
