What is the operating system of a computer?

Answer 1

The operating system serves many purposes. Talking at a high level operating system can be cosidered as a translator between user and computer(CPU).CPU or processor can understand only 0s and 1s, but the programs that we use today are written in somehigh level language like C or Java or something else. Now these programs ultimately had to be changed to 0s and 1s inorder to execute. This is the responsibility of Operating System. Then comes multitasking, we can execute multiple programs simultaneously in a single CPU, so this single execution core is shared among programs. This CPU management is also onus of Operating System.Not only CPU managent but many other resources are managed by Operatimg System like memory. Speaking at low level you cannot imagine a computer without Operating System. To facilitate access to the workings of the machine, which at its core only deals in zeros and ones.
Without an operating system, you would have to manually type in instructions to the computer using machine code or a low-level language, and call functions.

It would take several hours to be able to perform simple tasks such as typing word documents!

Operating systems pre-load all the commands, information, and configurations the computer needs to perform tasks automatically, easily, and using a simple interface, such as mouse point-and-click or voice command, as well as streamlining general use and allowing simplified keyboard commands like control-alt-delete
