Explain any two functions of an Operating system

Two functions of an Operating system are:

Processor Management — The OS (Operating System) ensures that each process/application receives enough time from the processor to function properly. It also tries to utilize as many processor cycles as possible for the real time work.

Memory Storage and Management — The OS (Operating System) manages the sharing of internal memory among the multiple applications. It also ensures that one process should not consume the memory allocated to another process. An OS has to make efficient utilisation of different types of memory (RAM, Cache, etc.) within the system, so as to ensure proper execution of every process.
