Computer Learning - Understanding Operating Systems
Have you learned computer? If not start learning Now.
Here are some of the things you will need to know about Computers.
Computer Basics: Understanding Operating Systems.
Operating Systems or OS is the same thing.
Let's Start-
What is an Operating System?
An operating system is the most important software that runs on a computer. It manages the computer's memory, processes, and all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's "language." Without an operating system, a computer is useless.
The Operating System's Job
You've probably heard the phrase boot your computer, but do you know what that means? Booting is the process that occurs when you press the power button to turn your computer on. During this process (which may take a minute or two), the computer does several things:
- It runs tests to make sure everything is working correctly.
- It checks for new hardware.
- It then starts up the operating system.

Once the operating system has started up, it manages all of the software and hardware on the computer. Most of the time, there are many different programs running at the same time, and they all need to access your computer's Central Processing Unit (CPU), memory, and storage. The operating system coordinates all of this to make sure that each program gets what it needs. Without the operating system, the software wouldn't even be able to talk to the hardware, and the computer would be useless.
