Basic Tutorial on Computer Operating System

Your computer can have an expensive motherboard, the fastest processor, lots of memory, and superior graphics, but it is completely useless without an operating system (OS). Every computer must have one. What is the operating system? You can look at it as being the "middle man". Application software such as a spreadsheet cannot communicate directly with hardware. Whether pressing a key on your keyboard or clicking your mouse, it's the computer operating system that provides the interface between software and hardware. It handles all of the computer's resources and has the ability to support devices from many different vendors via device drivers. All these tasks are quietly working behind the scenes without the user's knowledge.
