In this article I will review the top 10 linux distributions that you can try. For those who don't know linux , Linux is the Free and Open Source operating system modelled on UNIX. Linux is the most secure operating system out there. Linux has a number of different versions to suit nearly any type of user. From new to hard-core users, you'll find a "flavor" of linux to match your needs. These versions are called distributions (or "distros" in short). The most amazing thing about linux is that you can run the software from a CD or a USB thumb drive even without ever having to install it on your machine, so that you can take a test drive of the OS.
