2. Open-sourcing

3. What is Open-source ?
 The word “Open-source” comes from the notion that
companies or ad hoc groups would make availible
online the source code-the underlying programming
instructions that make a piece of software work and
then let anyone who has something to contribute
improve it and let anyone millions of others just
download it for their own use for free.

4. Some Succesful Open-source Project
 SENDMAIL
 APACHE WEB SERVER
 LINUX
 GNOME

5. WHAT IS APACHE ?
 It is a shareware program for Web server technology.

6.  The first version of Apache, based on the NCSA httpd
Web server, was developed in 1995.

7.  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 availible, anyone can
adapt the for specific needs, and there is a large public
library of Apache add-ons.

8.  Today Apache is one of the most successful open-
source tools... At the time, selling a product built on
top of an open-source program was a risky move on
IBM’ s part. To its credit, IBM was confident in its
ability to producing differentiated software
applications on top of the Apache vanilla. This model
has since been widely adopted, after everyone saw
how it propelled IBM’ s Web server business to
generating huge amounts of revenue.
