Computer Level 4: Operating System Whole Chapter Questions and Answers

1. When the process applies for equipment, the required equipment should be specified The category of preparation, instead of specifying a specific device, the system selects an idle device from the corresponding category of equipment according to the current request and device allocation and assigns it to the application process, which is called the independence of the device.

2. [Answer]: B [Analysis] The pipeline is realized at a point in time, and at most one thread is executing a subroutine of the pipeline.

3, https://pan.baidu.com/s/1mC3_QBc0cgO0y2AgE91OzA Extract Code: 1234 Computer Operating System Tutorial (4th Edition) Exercise Answers and Experimental Guidance is a book published by Tsinghua University Press in 2014. The author is Zhang Yaoxue.

4、. Request Interruption When an interrupt source needs the CPU to interrupt service for it,How to select the best trade data provider the interrupt request signal is output to position the interrupt request trigger of the interrupt control system and request an interrupt from the CPU. The system requires the interrupt request signal to be maintained until the CPU interrupts the response.

Is the operating system a multiple-choice question of the computer system?

1. In the single-channel system, when the operation waits for the I/O operation to be suspended, the CPU (B) until the I/O operation is completed.

2. The operating system is A in the computer system. Core system software. Operating system (abbreviated as OS) is a computer program that manages computer hardware and software resources, and is also the core and cornerstone of a computer system.

3. The operating system is a system software (or program collection) that is convenient for users to manage and control computer software and hardware resources.

Operating system... Ask for an answer

Answer: C () is not the main concern of the operating system. Answer: D () The operating system allows multiple terminals to be connected to a host at the same time, and multiple users can use computers interactively at the same time through their respective terminals. Answer: C Judgement Question Batch processing system is a system that realizes human-computer interaction.

The five major functions of the operating system include: process and processor management, job management, storage management, device management, and file management.

A distributed operating system is an operating system used to manage distributed computer systems.It connects a group of computers through the network to complete specific tasks together. It is widely used in cloud computing, large data centers, artificial intelligence and other fields. Common distributed operating systems include Google's Fuchsia, Hadoop and ZooKeeper.

What is the main purpose of introducing computer operating systems

1. Manage resources for management, improve resource utilization, etc. An operating system is a group of interrelated system software programs that supervise and control computer operation, use and run hardware, software resources and provide public services to organize user interaction. The main purpose of introducing the operating system is to manage resources, improve resource utilization, and facilitate users' use.

2. The operating system is a system software configured to control and manage various resources of the computer in order to give full play to the efficiency of the computer system and facilitate users to use the computer. The operating system is the most basic system software that runs directly on the computer and is the core of the system software. Any computer must configure the operating system.

3. The main purpose of configuring the operating system in the computer system is to manage the computer system to improve the efficiency of system use and reasonably organize the workflow of the system to improve the system throughput. The main function of the operating system is to manage processes in the computer system, including memory management and processor management, as well as device management and file management.

4. The main purpose of configuring the operating system in the computer system is ().

5. The main functions of the operating system include: managing hardware resources, such as memory, disk space, processor and input/output devices. Manage the file system and provide file storage, reading and management functions. Provide a user interface to facilitate the interaction between users and computers. It provides multitasking capability and allows multiple programs to run at the same time.

6. The goal and role of the operating system is to provide a convenient, effective and safe computer environment to manage and coordinate hardware and software resources to meet the various needs of users. Convenience: The operating system makes the use of computer hardware and software resources simpler and more convenient.
