I would like to share with you what are the five major functions of a computer operating system. I believe most people do not know much about it, so share this article for your reference. I hope you will learn a lot after reading this article. Let's learn about it!

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 file storage, retrieval, sharing and protection.

The five functions of computer operating system are: CPU management, storage management, file management, device management and job management.

1. Processor management. When multiple programs are running at the same time, the problem of processor (CPU) time allocation is solved.

2. Job management. A program that completes an independent task and the data it needs make up a job. The main task of job management is to provide users with a computer interface to run their own jobs conveniently, schedule and control all jobs entering the system, and make use of the resources of the whole system as efficiently as possible.

3. Memory management. Allocate storage space for individual programs and the data they use, and ensure that they do not interfere with each other.

4. Equipment management. The device is allocated according to the request of the user to use the device, and the request of the device (called interrupt) can be received at any time, such as the request for input information.

5. Document management. Mainly responsible for file storage, retrieval, sharing and protection, to provide users with the convenience of file operation.

The above is all the contents of the article "what are the five functions that computer operating systems usually have?" Thank you for reading!
