Linux Administration

.
Linux is PC-UNIX in which the kernel was created for PC/AT compatibles by Linus Torvalds . The name is derived from the kernel's creator.

Advantages of using Linux

• Free (free of cost and generally free in what you can do with it)
• Open-source (the code is available)
• Secure
• Available on a number of different architectures and platforms
• Designed for excellent performance

The combination of the kernel and some application software supporting it for use as a OS is called a "distribution". There are basically three types of distibution

1. RedHat series (Redhat, fedora, madrik, Turbo,Vine)
2. Slackware series (Slackware, Plamo Linux)
3. Debian series (Debian, Ubantu)

Out of these Redhat LINUX is most used one and one can find maximum people ceritified in redhat linux. Training and courseware is avalable for redhat. But debian is the most stable amongst all these versions of linux, as per my experience.
