The correct answer is (d). Virus Protection.
An operating system (OS) is a system software that manages computer hardware and software resources and provides common services for computer programs.
The four main functions of an operating system are:
- Memory management: The operating system manages the computer’s memory by allocating memory to different programs and processes.
- Input/output management: The operating system manages the computer’s input and output devices, such as the keyboard, mouse, and printer.
- Process management: The operating system manages the computer’s processes by scheduling them to run on the CPU and by providing them with the resources they need.
- File management: The operating system manages the computer’s files by creating, deleting, and organizing them.
Virus protection is not a basic function of an operating system. It is a security feature that is often provided by an operating system, but it is not essential for the operating system to function.
