|
||
|
University of Helsinki in Finland by a young student named Linus Torvalds. At
|
||
|
this time the student was working on a UNIX system that was running on an
|
||
|
expensive platform. Because of his low budget, and his need to work at home, he
|
||
|
decided to create a copy of the UNIX system in order to run it on a less
|
||
|
expensive platform, such as an IBM PC. He began his work in 1991 when he
|
||
|
released version 0.02 and worked steadily until 1994 when version 1.0 of the
|
||
|
Linux Kernel was released. The current full-featured version at this time is
|
||
|
2.2.X; released January 25, 1999, and development continues.</P

> General Public License (also known as GNU GPL) and its

source code is freely available to everyone who downloads it via the Internet. The CD-ROM version of Linux is

also available in many stores, and companies that provide it will charge you for the cost of the media and support.
|
||
|
Linux may be used for a wide variety of purposes including networking, software development, and as an end-user
|
||
|
platform. Linux is often considered an excellent, low-cost alternative to other more expensive operating systems
|
||
|
because you can install it on multiple computers without paying more.
