FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -We can use a computer without its operating system. This statement is false. Explanation: An operating system is a program that controls the execution of applications programs and acts as an interface between applications and the computer hardware.

Detailed explanation-2: -The hardware provides the raw power and functionality that enables the computer to work, and the operating system controls the bulk of the hardware’s activity. You’d have a hard time using a computer without an operating system, as all of your hardware parts would be unable to communicate with one another.

Detailed explanation-3: -Software constantly stands by to await user input, at which point it then performs the necessary action by sending a signal to the hardware. Hardware performs the required action by accessing memory stored as bits on memory chips.

Detailed explanation-4: -It manages the computer’s memory and processes, as well as 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.

Detailed explanation-5: -Without an operating system, You cannot run a program that was written to be run in an operating system. Most programs are of this sort. You could write a program that runs without an operating system but this would be a very hard task, mainly because the operating system provides drivers for all the hardware.
