OS

Operating system. Simply, a program that runs your computer. Examples of an operating system are CP/M, DOS, Windows, Mac OS, Linux, and Palm OS, though there are many more. One will oftentimes become overly attached to their OS, preaching it as though it were a religion and shunning all who use anything even slightly different.

Man: My OS of choice is Windows XP.
Woman: My OS of choice is Mac OS X.
Man & Woman: (killing eachother)
Supa-Nerd: My OS of choice is CP/M! 8086 FOREVAH!!!

An operating system is the main software that runs a computer, without an operating system a computer is almost useless.

There is no best operating system, they all have their advantages/disadvantages and were all developed with some kind of goal in mind.

1: All the company's servers used Unix (OS), but now they use Linux (OS).

2: George had a quadruple boot with multiple OSs running on his PC, it ran Microsoft Windows Vista Ultimate, Mac OS X Leopard, and two flavors of Linux.
