1. The role of the operating system Process management, also known as processor management, its main responsibility It is to reasonably allocate the time of the processor and effectively manage the operation of the processor. Memory management Because multiple programs share memory resources, the main task of memory management is to allocate, protect and expand memory.
2. Two important roles of the operating system: improve the efficiency of the system through resource management; improve the human-computer interface and provide users with a friendly working environment. Definition of operating system: It is a collection of programs and related documents that manage various software and hardware resources in a computer. It is a kind of system software.
3. The main function of the computer operating system is process management, which is mainly process scheduling. In the case of a single user and a single task, the processor is only monopolized by one user's task. The work of process management is very simple.
4. The important functions of the operating system are as follows: (1) Manage the resources in the computer system, including all hardware (processors, memory and external devices, etc.) and corresponding software, complete tasks smoothly with the cooperation of hardware and operating systems, and improve system work efficiency.
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.
Learn Linux architecture and commands. Under Linux, it is executed through commands. Learn to help with man and commands, and be familiar with the operation of various common commands. Learning shell scripts, for professional Linux personnel, shell scripts are a must.
Learn computer from scratch and learn how to operate first: To learn computer, you should first learn how to operate, including being proficient in using the keyboard, using the mouse, being able to basically use the operating system, and then learning typing (professional typing must learn five strokes), proficient in using the operating system.
We can use the pulley to slide back and forth to turn the web page up and down. Use of keyboard: There are many keys on the keyboard. It is recommended to learn how to type, switch input methods, and knowFind someone who can teach you these operations such as shortcut keys on the keyboard, and then practice by yourself and add more memory.
1. The transfer instruction with relative addressing accounts for 3 bytes. The first byte is the operation code, and the third byte is the relative displacement (complement code representation), and the data is stored in the memory with a low-byte address as the word address. Whenever the CPU removes a byte from the memory, it automatically completes (PC) + 1 → PC.
2. To learn computers, you must first build confidence. Computers are not difficult. Even if you have never been in contact with computers, as long as you are willing to learn, you will definitely learn it little by little.Start with the mouse and keyboard. To learn a computer, you must first learn how to use the mouse and keyboard. As long as you know how to use it, it doesn't matter if the operation is slow.
3. First of all, for beginners, learning computer technology should first start from two aspects, one is to learn the operating system knowledge, and the other is to learn the programming language knowledge.
4. Learn the content order of the computer: basic operation, typing speed, knowledge positioning, office software, professional knowledge. Basic operation: You need to master various methods such as computer power-on, shutdown, standby, shutdown, restart, etc., and use the basic functions of the mouse, copy, paste, scroll, etc.
1. Learn to add peripherals and install device drivers (such as modem);Familiar with Grub/Lilo booter and simple repair operations; familiar with the name and public use of the system's inherent directory; learn to access other file systems with mount commands; understand vi, gcc, gdb and other commonly used editors, compilers, debuggers; learn simple networks in the linux environment.
2. If you want to learn Linux, it is strongly recommended to learn through this set of books "Brother Bird's Linux Private Dishes", which is easy to understand. The editor learned Linux through this set of books.
3. For those of us who have just started to learn Linux, we feel that this system is really difficult to learn, and we are not used to it. Everyone must be familiar with the often used window system, so it is said that familiarity makes perfect. Beijing Peking University Blue Bird believes that learningLearning Linux lies in accumulation. Master a few commands every day, practice more and knock several times every day, and you will gradually master them.
1. Personally, I think it is particularly 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.
2. 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.
3. Then it can be concluded that the role of the learning operating system in the university is as follows: process control: create a process for the job, 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).
4. 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.
5. Linux has high security. Compared with other operating systems, Linux has much fewer software vulnerabilities and virus threats. By learning Linux, you can learn more about system security.
