Among all OS in the market, Linux is the most ported to various computer hardware platforms. It runs supercomputers, servers, and personal computers. There are appliances and electronics that work through embedded Linux microchips as well. Linux, as a home and work desktop operating system, is gaining popularity over the past few years.

Mainstream versions are available online and versions for server systems can be modified based on workflow requirements.
Linux has various versions available, most are free downloads. There are a few commercial distributions available at small contributions that comes with tech support. Despite mainstream and server system variatinos of Linux, they are all united by an official mascot named Tux.
