Explanation:
Apache is a public-domain Web server developed by a loosely-knit group of
programmers. The first version of Apache, based on the NCSA httpd Web server, was
developed in 1995. Because it was developed from existing NCSA code plus various
patches, it was called a patchy server – hence the name Apache Server. As a result of its
sophisticated features, excellent performance, and low price (it’s free), Apache has
became the world’s most popular Web server. By some estimates, it is used to host more
than 50% of all Web sites in the world. Core development of the Apache Web server is
performed by a group of about 20 volunteer programmers, called the Apache Group.
However, because the source code is freely available, anyone can adapt the server for
specific needs, and there is a large public library of Apache add-ons. In many respects,
development of Apache is similar to development of the Linux operating system. The
original version of Apache was written for UNIX, but there are now versions that run
under OS/2, Windows and other platforms.
