For Chapter 21, I have chosen the www.apache.org web link to surf in depth. I have learned that The Apache Software Foundation (ASF) is a non-profit organization incorporated in the United States of America. It was formed primarily to provide a foundation for open, collaborative software development projects by supplying hardware, communication, and business infrastructure, create an independent legal entity to which companies and individuals can donate resources and be assured that those resources will be used for the public benefit. It  provides a means for individual volunteers to be sheltered from legal suits directed at the Foundation's projects.

            In this web site, I am interested in the Apache HTTP Server Project. The October 2003 Netcraft Web Server Survey found that more than 64% of the web sites on the Internet are using Apache, thus making it more widely used than all other web servers combined. The Apache server is free and it could be downloaded off the website. Currently there are two versions. They are the 1.3 and the 2.0. I have learned why the Apache server is free. According to them, Apache exists to provide a robust and commercial-grade reference implementation of the HTTP protocol. They believe the tools of online publishing should be in the hands of everyone, and software companies should make their money providing value-added services such as specialized modules and support, amongst other things. They say that it is often seen as an economic advantage for one company to "own" a market - in the software industry that means to control tightly a particular conduit such that all others must pay. This is typically done by "owning" the protocols through which companies conduct business, at the expense of all those other companies. To the extent that the protocols of the World Wide Web remain "unowned" by a single company, the Web will remain a level playing field for companies large and small. Thus, "ownership" of the protocol must be prevented, and the existence of a robust reference implementation of the protocol, available absolutely for free to all companies, is a tremendously good thing.

            I personally think that because it is free, that why many people are using it.
