What are the five major functions that computer operating systems typically have?

Five major functions: 1. Processor management; when multiple programs are running at the same time, solve the problem of processor time allocation; 2. Job management. 3. Memory management: allocate storage space for each program and the data it uses, and ensure that they do not interfere with each other. 4. Equipment management. 5. File management; mainly responsible for the storage, retrieval, sharing and protection of files.

Computer operating systems usually have five major functions: processor (CPU) management, storage management, file management, device management and job management.

1. Processor management. Solve the problem of processor (CPU) time allocation when multiple programs are running at the same time.

2. Job management. A program that completes an independent task and the data it requires form a job. The task of job management is mainly to provide users with a computer interface so that they can conveniently run their own jobs, schedule and control all jobs entering the system, and utilize the resources of the entire system as efficiently as possible.

3. Memory management. Allocate storage space for each program and the data it uses, and ensure that they do not interfere with each other.

4. Equipment management. Device allocation is performed based on the user's request to use the device, and it can also receive device requests (called interrupts) at any time, such as requiring input of information.

5. File management. It is mainly responsible for the storage, retrieval, sharing and protection of files, and provides users with convenient file operations.
