Answer 2

Answer:

Functions of operating system are:

Memory management

File management

Process management

Explanation:

An operating system is a software package that runs application programmes and serves as a communication link (interface) between the user and the computer hardware.

The allocation of resources and services, such as memory, devices, processors, and information, is the primary duty of an operating system. A traffic controller, a scheduler, a memory management module, I/O programmes, and a file system are all included in the operating system to manage these resources.

Memory Management - The primary memory, often known as main memory, is managed by the operating system. The main memory consists of a vast array of bytes or words, each of which is allocated an address. Main memory is rapid storage that the CPU can access directly. A programme must first be loaded into main memory before it can be executed. For memory management, an operating system performs the following tasks:

It keeps track of primary memory, i.e., which user programmes use specific bytes of memory.

Processor Management — In a multi-programming environment, the operating system determines the sequence in which programmes access the processor and the amount of processing time each process has. Process is the name for this OS feature.

File Management - A file system is divided into directories to make navigation and usage more efficient. Other directories and files may be found in these directories. The following file management tasks are performed by an operating system. It keeps track of where data is kept, user access settings, and the state of each file, among other things... The file system is the name given to all of these features.
