Operating System (OS)

We all know that today's computers use an operating system to operate. Let's talk a bit on what exactly is an OS and what it does.

You can think of the OS as the middle person in a business transaction. Assume that in this case the business transaction is the moving of your mouse across the screen, opening your web browser or opening your word processor. These commands are taken care of by the OS installed on your computer. You do not have to worry about the nitty gritty of electronics and get your hands dirty under the hood to perform these tasks yourself. You just move and click your little mouse and everything is done for you by your OS. Basically, we can say that without an OS, a computer is practically useless to us!
