The operating system that has evolved into Mac OS X hosted the first web server, but much has changed since 1989. Sure, Mac OS X Server still has a web server, although now it runs Apache. And Apache is one of the hundreds of open source products now built into Mac OS X Server. Mac OS X Server can now manage thousands of client computers using Open Directory and Profile Manager. Over the years, Mac OS X Server has been a file server, a podcasting server, a video streaming server, and an imaging server for Mac OS X client computers. Basically, Mac OS X Server can do most anything that administrators might want a server to do.
