Why learn the operating system

Personally, I think it is especially useful to learn the system. Because learning this not only has a great impact on our daily life, but also a great gain for us to learn computers. Think about how troublesome it is to type a lot of code to open a software in addition to the black command line on the screen.

Because the operating system is a huge program with very important performance, it generally takes decades to maintain, so they are a good place for students to learn such trade-offs. Students with a pair of sharp eyes to find suitable design points are needed in industry.

Then it can be concluded that the functions of the learning operating system in the university are as follows: process control: create a process for homework, cancel (terminate) the completed process, and control the state conversion of the process during the operation. Process synchronization: The main task is to coordinate the operation of multiple processes (including threads).

The operating system also provides an operation interface for users to interact with the system. Process management process management. Also known as processor management, its main task is to reasonably allocate the time of the processor and effectively manage the operation of the processor. Memory management Memory management.

Learn Computer Operation Department What books to use

The books to learn operating systems are: "Computer Operating System" is relatively detailed. With the book of "Computer Operating System" learning guidance and problem-solving, you can consolidate and summarize what you have learned, and you can also test yourself.

"The Structured Method of Computer Composition" is a book published by Machinery Industry Press. The author is Tanenbaum (A.S.). This book can be used as a computer major.The textbooks or reference books for undergraduates to learn computer composition and structure courses can also be used for reference by other relevant professionals.

Of course, there is also "Computer System Structure" written by Western Power, and Western Power's Computer Operating System (Third Edition), and Tang Shuofei, the author of Computer Composition Principle, is the high education version. Mathematics course: Linear Algebra published by Higher Education Press and Probability Statistics compiled by Zhejiang University.

How to self-study the operating system

1. Learn to surf the Internet. After understanding the basic operation of the mouse and keyboard, you should open the system's built-in browser and browse the first web page. Open the web page to browse at will, and click everywhere to explore. I believe you will fall in love with the computer soon.Learn to use search engines.

2. Learn Linux architecture and commands. Under Linux, it is executed through commands. Learn to use man and command help, and be familiar with the operation of various common commands. Learning shell scripts, for professional Linux personnel, shell scripts are a must.

3. Learn computer operation from scratch: If you want to learn computer, you should first learn how to operate, including being proficient in using the keyboard, using the mouse, and being able to basically use the operating system, and then learn typing (professional typing must learn five strokes) and be proficient in using the operating system.

4. We can use the pulley to slide back and forth to turn the web page up and down. The use of the keyboard: There are many keys on the keyboard, and you can learn computer construction from scratch.Learn how to type, switch input methods, know keyboard shortcuts and other operations. Find someone who can teach you, and then practice diligently and remember more.

5. First of all, let's find out what the operating system is? Why does the operating system appear? Domestic operating systems are mostly secondary development operating systems based on Linux.

6. Self-study computer can be carried out according to the following steps: Establish basic knowledge: First, understand the basic principles and components of computers. Learn the basic concepts of computers, such as hardware, operating systems, software, etc.

Operating System Principle

Operating System (English; OperatingSystem, abbreviated as OS) is a bionic application of the human brain. Its working principle is very similar to the process of the brain controlling the human body. An operating system is a set of programs that manage computer hardware and software resources, and it is also the core and cornerstone of the computer system.

The operating system is the bridge responsible for communicating computer hardware and computer software in the computer structure. The operating system directly directs the hardware of the computer, such as the screen, keyboard and so on. The software, on the other hand, calls the function of the operating system, so as to achieve the purpose of calling computer hardware.

Hello! An operating system is a collection of system software that manages computer hardware resources, controls the operation of other programs and provides users with interactive operation interfaces.

In order to protect the operating system and important operating system tables from the interference of user programs, the operating system usually uses two modes to manage the process: privileged mode [It is also known as system mode, control mode or kernel mode, and user mode.

What is an operating system? What are the functions of the operating system?

Operating System (OS) is a collection of programs that control and manage computer software and hardware resources, and organize multiple users to share multiple resources in the most reasonable and effective way. Any other software must be supported by the operating system to run. .

The operating system is a collection of system software that manages computer hardware resources, controls the operation of other programs and provides users with interactive interfaces.

Operating System (abbreviated as OS) is a computer program, which is an intermediate software for managing and maintaining computer system resources.

The role of the operating system: The operating system is located between the underlying hardware and the user, which is the bridge between the two. Users can enter commands through the user interface of the operating system. The operating system interprets commands, drives hardware devices, and meets user requirements.

The operating system is a control program. The operating system is the control and management center of the computer system. From the perspective of resources, it has four functions, including processor, memory management, device management and file management. Commonly used systems include DOS operating system, WINDOWS operating system, UNIX operating system, Linux, Netware and other operating systems.

The operating system is a huge management control program, which roughly includes five aspects of management functions: process and processor management, job management, storage management, device management, and file management. At present, the common operating systems on microcomputers include DOS, OS/UNIX, XENIX, LINUX, Windows 2000, Netware, etc.
