What is the parallel processing function of a computer system?

Basic functions of computer system parallel processing: 1 Single central processor computer that can execute multiple instructions or process multiple data items at the same time; 2 Multi-processor system; 3 Widely adopt various parallel measures in single-processor; 4 Develop from single-processor to multi-processing with various coupling degrees Machine system.

Pallel processing computer system parallel computer sYstem is a computer system that executes multiple tasks or instructions at the same time or processes multiple data items at the same time. Early computers were serial bit-by-bit processing, which was called serial computers. With the development of computer technology, modern computers have different degrees of parallelism.

Pallel refers to the simultaneous execution of multiple tasks in the computer system. In a parallel system, multiple tasks can be performed at the same time, and each task has its own processor unit or computing unit. The advantage of this method is that the utilization rate of the system is high, because the computer system can perform other tasks while waiting for the completion of the task.

Ask for the advice of the computer professional operating system! [ Distributed operating system] and [multiprocessor operating system...

1. Multiprocessors Operating System is generally applied to parallel processors. The parallel processor is also known as the SIMD computer. It is an array composed of multiple processing units under the control of a single control component, so it is also called an array processor.Multiprocessor is a system composed of multiple independent processors.

2. Distributed Software Systems Distributed Software Systems is a software system that supports distributed processing. It is a system that performs tasks on a multi-processor architecture interconnected by communication networks.

3. An operating system that provides network communication and network service functions on the basis of the functions of the usual operating system. Distributed operating system. An operating system based on a computer network that interconnects physically distributed data processing systems or computer systems with autonomous functions.

4. According to the usage environment of the operating system and the consideration of the operation processing method, it can be divided into batch processing system, time-spliting system and real-time system;According to the number of supported users, it can be divided into single-user system and multi-user system; according to the hardware structure, it can be divided into network operating system, distributed system, multimedia system, etc.

What is a batch processing operating system?

Batch processing operating system is an operating system running on large and medium-sized computers in the 1970s. At that time, due to the low efficiency of CPU use of the single-user single-task operating system and the full utilization of I/O equipment resources, a multi-channel batch processing system was created, which mainly ran on large and medium-sized machines.

What is batch processing: Batch processing is composed of multiple dos commands, and double-clicking can execute the commands inside. ( Microsoft System) Batch processing: Desktop files can be typed by double-clickingOpen, and java can't be opened with a double click, because java is a class file that needs a virtual machine to run to open it.

The operating system is the core of all computer software. It is the interface between the computer and the user. It is responsible for managing all computer resources and coordinating and controlling the operation of the computer. Batch processing system: The operator loads the operation into the computer in batches and is managed and run by the computer. Users cannot intervene during the operation of the program.

Batch is not an operating system in the strict sense. Although it can be supervised by Monitor and developed in assembly language, it is only the prototype of the operating system.

The sewage treatment tank system includes those pools

1. TraditionallyIn the domestic sewage treatment process, there are three main treatment units known as the three major pools of sewage treatment, which are pretreatment tank, aerobic biological pool and sedimentation tank.

2. Septic tank refers to a small treatment structure that precipitates domestic sewage and anaerobically digests sludge. Initial sinking tank is a structure used to remove sinkable and floating objects in sewage treatment.

3. Laboratory sewage treatment equipment usually includes the following parts: sewage collection tank: used to collect sewage generated by the laboratory, and a closed collection tank is usually used to avoid the spread of odor and pollutants. Filter: It is used to filter impurities and pollutants in sewage to ensure the smooth progress of subsequent treatment.

4. Adjust the pool: adjust the amount of water and balance the water quality.Improve the impact load resistance of the system. Integrated sewage treatment equipment: the main process is A/O biochemical process, with built-in precipitation and sludge backflow system. The shell is mechanically wound with fiberglass tank body, which is designed to be buried in the ground.

What two categories can the information system be divided into at present? Which parts does each category include

1. Automation, abbreviated as OA) five types. The management information system includes: manager information system, marketing information system, manufacturing information system, financial information system, human resources information system and information resource information system are divided into two levels. This is a logical MIS rather than a physical MIS, also known as organizational information system.

2. Computer systems can be divided into two categories: software system and hardware system.The hardware system is mainly composed of central processor, memory, input and output control system and various external devices. The central processor is the main component of high-speed computing processing of information, and its processing speed can reach more than hundreds of millions of operations per second.

3. Information systems are divided into three categories: transaction processing system, management information system and decision support system. ( 1) Transaction processing system (TPS) is mainly used to support the daily activities of operational personnel.

4. According to the contact information between its parts, it can be divided into two types: centralized and distributed.

5. A complete computer system includes two major parts, namely hardware system and software system. The hardware part of a computer consists of five basic parts: operator, controller, memory, input device and output device, also known as the five major components of the computer.The computer software part is divided into two categories: system software and application software.

How to deal with computer system stuck

1. Turn off hibernation If you don't use the hibernation function at ordinary times, you can turn off the hibernation function and delete the system hibernation files.

2. Increase memory or replace the hard disk: If the computer's memory or hard disk space is insufficient, it will also cause the system to get stuck. You can consider adding memory or replacing the hard disk to improve computer performance. Optimize system settings: You can improve computer performance by optimizing system settings.

3. Computer stuck is a problem that many people will encounter, so what should they do? This article will introduce 6 ways to solve computer jamming, hoping to help you.To clean the inside of the machine, it is recommended to clean the inside of the machine thoroughly. If you can unplug it, unplug it and clean up the golden finger interface, etc.

4. The processing is as follows: Adjust the performance of the computer processor. First, right-click "This Computer" on the desktop, select "Properties", select "Advanced System Settings" after entering the page, enter "Settings" in the performance options, and then select "Adjust to Best Performance" in the visual effects.

5. First, click the start icon of the computer. Find the Windows system in the list and open the task manager. Click the details and click the cpu. Select the application with high CPU occupancy and click End Task.

6. Computer jamming is a problem that many people will encounter, which not only affects the user experience, but also reduces work efficiency.This article will introduce 5 tips to help you easily solve the problem of computer stuck. Partition management takes up more system resources on the desktop of the computer.
