What is Linux?
Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991 by Linus Torvalds.
Benefits of using linux
For most of us it's not a secret that using Windows nowadays gives you a lot of problems ranging from issues of vulnerability, pricing and even hardware compatibility. Problems like these should be easily resolved if not absent as every second of wasted time means either lost money or recreation time. Having a computer is all about maximizing the cost, efficiency and entertainment. And if these can't be met by operating systems, there's actually no use for them.

Windows, the most popular operating system, would have to meet the demands of the consumers to stay in the market as another operating system, Linux, multi-functional, efficient and cost-maximizing, has increasingly gained users.
What is Linux used for?
*Web Serving
Nearly 60% of all websites on the Internet are run using an Open Source program named "Apache." Most often, it's run on Linux. If you've ever surfed the web, you've (indirectly) used Linux!
Linux is based on Unix, an operating system developed in the 1970s and which is still used heavily today, especially to run the Internet. Linux is used both to run parts of the Internet, as well as to run small and large networks in coporations, offices and homes.
Since Linux is stable, secure and robust, it's perfect for storing huge databases of information.
People like us use Linux on our home and work computers, because of its stability and flexibility.
*Scientific Computing
Many dozens (or even hundreds or thousands) of Linux systems can be clustered together to work on a single task (like weather forecasting, physics simulations, computer graphics rendering, etc.)
A large collection of inexpensive PCs running Linux can be just as powerful as a mainframe computer, but at a tenth of the cost.

*Home Computing
And, of course, people like us, and people like you, can and do use Linux on a daily basis at home and in the office
How good is Linux, how is it different from windows and can you use Skype with Linux ?

Linux is different, you can't use exe files and if you have some problem you will have to fix it yourself by reading documentation and searching forums. For playing DVDs you will have to install codecs. Skype has a Linux version.

Most important thing to know is that there is always more than one way to accomplish something on linux.
Centos is most like redhat.

You can't learn linux in one and half weeks so find out what the company does and narrow your focus.
