What are the basic functions of the operating system?

The operating system (Operating System, OS for short) is a computer program that manages computer hardware and software resources. The operating system needs to handle basic tasks such as managing and configuring memory, determining the priority of system resource supply and demand, controlling input and output devices, operating the network, and managing the file system. The operating system also provides an operating interface for users to interact with the system.

The operating system mainly includes the following functions:

1. Process management. Its main job is process scheduling. In the case of single user and single task, the processor is only for one user. Exclusively for one task, the work of process management is very simple. However, in the case of multi-programming or multi-user, when organizing multiple jobs or tasks, it is necessary to solve the problems of processor scheduling, allocation and recycling.

2. Storage management is divided into several functions: storage allocation, storage sharing, storage protection, and storage expansion.

3. Device management has the following functions: device allocation, device transmission control, and device independence.

4. File management: file storage space management, directory management, file operation management, and file protection.
