The correct answer is: Operating System.
The operating system is a software program that manages the computer’s hardware and software resources and provides a platform for other programs to run. It is responsible for tasks such as scheduling tasks, managing memory, and controlling input and output devices.
Memory is a physical device that stores data and instructions that the computer can access quickly. It is divided into two main types: RAM (random access memory) and ROM (read-only memory). RAM is temporary storage, which means that it is erased when the computer is turned off. ROM is permanent storage, which means that it is not erased when the computer is turned off.
I/O devices are devices that allow the computer to communicate with the outside world. They include input devices such as keyboards and mice, and output devices such as monitors and printers.
The control unit is a
part of the CPU that is responsible for fetching instructions from memory, decoding them, and executing them.In conclusion, the operating system is the supervisor of computer activity because it is responsible for managing the computer’s hardware and software resources and providing a platform for other programs to run.
