What is Linux?

Linux
Just like Windows and Mac OS X, Linux is an operating system. An operating system is software that manages the communication between your application software and your hardware.
Why use Linux?
Linux has evolved into one of the most reliable computer ecosystems on the planet.
Combine that reliability with zero cost of entry and you have the perfect solution for a server or desktop platform.
That’s right, zero cost of entry...as in free beer.
You can install Linux on as many computers as you like without paying a cent for software or server licensing (including costly Microsoft Client Access License – CALs).
