I really like the Apache Web server, in case that fact hasn't become clear as you've read through this lesson. It's not only a wonderful software package, but also a great testament to the value of the Internet itself, a key factor in the continued success of the Apache development team. Free software isn't inferior to expensive packages, and in many cases it's quite a bit better!
Again, please visit http://www.apache.org/ to learn more about the Apache project and learn about how you can download your own Web server for your computer.
