Self Summary of questions and answers for the "Operating System" (2)

1. The batch operating system realizes automatic control without human intervention, and the time-sharing operating system realizes human-computer interaction dialogue. These two operating systems have their own advantages. In order to give full play to the advantages of batch processing systems and time-spliting systems, the operating system configured on a computer system often has both batch processing capabilities and the ability to provide time-spliting interaction.

2. Control of interactive operations: one is to operate and use the interface, and the other is to interpret and execute commands.The operation interface includes operation control commands, menu technology and window technology. Explanation and execution of commands. One type is the corresponding processing module in the operating system to directly interpret the execution; the other type must create a user process to interpret the execution.

3. In a multi-program environment, the operating system allocates resources with __C__ as the basic unit. A. Program B. Instruction C. Process D. Job (10) If there are n processes in the system, the maximum number of processes in the ready queue is __B__.

4. Job execution steps The operating system provides users with two ways to express the job execution steps: job control language and operation control commands. The operation control language forms batch processing operation. Operate control commands for interactive processing.

5. In order to helpThe majority of self-candidates have learned the operating system course well and successfully passed the course examination. On the basis of years of computer teaching and guiding students to take the exam, we have compiled this "Operating System Self-study Examination Synchronous Supporting Questions" according to the self-examination outline and the self-examination group.

Several questions about the operating system

1. Improve the ability of the system: When a path is disconnected due to a controller or channel failure, other channels can be used.

2. Memory problems. Because of this reason, there are many problems, which are generally caused by poor chip quality. Sometimes the problem can be solved by modifying the memory speed in the CMOS settings. If it doesn't work, you can change the memory. ( 2) Mainboard problems.

3. Process scheduling is an important problem in the operating system. Its basic principle is to select a process from the ready queue according to a certain algorithm, assign the CPU to it, and make it execute. There are many kinds of process scheduling algorithms. The common ones are first-come, first-served (FCFS), short job priority (SJF), time slice rotation (RR), etc.

4. Common fault 7: When booting and installing Windows from the hard disk to detecting disk space, the system prompts insufficient memory. Such failures are generally caused by the user adding the emm38exe file to the config.sys file. As long as it is blocked, it can be solved. Question. Optical drive Optical drive is one of the accessories with the shortest service life in computer hardware.

5In general, the operating system is installed on the C disk. In view of the fact that the operating system may have unexpected problems and cause the system to crash, the data on the C disk may be lost. The files are stored in the D disk or other disks. Even if the system fails, the data will not be lost.

"Operating System" Fill-in-the-blank Questions Summary (1)

1. In the batch processing and time division system, the tasks controlled by the time-sharing system are often called foreground tasks, while the tasks controlled by the batch processing system are called background tasks. Industry. The operating system provides users with two types of usage interfaces, which are the operator interface and the programmer interface.

2. Fill in the blanks. The operating system is to control and manage various hardware in the computer system.The system software that effectively organizes multiple programs to run is the interface between the user and the computer.

3. Fill in the blanks one by one in the computer operating system review questions: 1. The operating system provides users with three types of usage interfaces, which are command methods, system calls and graphical user interfaces. Two. The data transmission control methods between the main memory and the peripherals include program direct control, interrupt drive, DMA and channel control.

4. Fill in the blanks Exercise 1. The basic functions of the operating system are Array and Array. Use a program-level interface to call the functional modules inside the operating system, which is called Array. In the Array operating system, the time to respond to a new task must be within the time specified by the accused object.
