Linux

An Open Source computing platform based on the robust core of commercial Unix systems. Developed by a Finnish programmer named Linus Torvalds in the early 90′s, the Linux core is typically distributed with hundreds of other ‘packages’, commonly known as GNU/Linux. There are dozens of popular distributions (or ‘flavours’) of GNU/Linux such as the popular RedHat, Mandrake, Slackware and Debian. GNU/Linux is become popular because it is free, flexible and secure.
