Question

give me a short note on OPERATING SYSTEM(OS)?

Answer 1

It is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs,excluding firmware, require an operating system to function.

Answer 2

The operating system (OS) is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs and applications.

Computer operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the storage drives, and controlling peripheral devices, such as printers. 

For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop — it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system.
