What is the basic composition of a microcomputer?

1. In appearance, the basic configuration of the microcomputer is four parts: mainframe, keyboard, mouse and monitor. In addition, microcomputers are often equipped with printers and speakers. A complete microcomputer system consists of two parts: a hardware system and a software system.Hardware part A complete computer system includes two major parts, namely hardware system and software system.

2. Microcomputers usually consist of five parts: controller, operator, memory, input device and output device. Microcomputers usually have controllers, arithmetic units, memory, input devices and output devices. It consists of five parts.

3. A microcomputer is a small electronic computer composed of large-scale integrated circuits. It is a bare metal composed of microprocessor-based, equipped with internal memory and input and output (I/O) interface circuits and corresponding auxiliary circuits.

4. Three parts of the basic structure: microprocessor, (memory, I/0 interface, system bus) peripherals, power supply, microcomputer is microBased on the logic device, it is a bare metal composed of internal memory and input and output (I/0) interface circuit and corresponding auxiliary circuit.

Self-examination "Computer System Structure" Q&A Summary (3)

1. Take IBM370 as an example to explain why interruptions are classified and divided into several categories. There are many interrupt sources for large multi-purpose machines. Each interrupt source forms a separate entrance, which will make it difficult to implement hardware and costly. Therefore, it can be classified. Each category of interrupt service program entrance is transferred from the software to the corresponding processing part.

2. The hardware structure of the computer system is mainly composed of four parts: controller, operator, memory and input and output devices, among which, controllers and operators are collectively called central processors.

3. In terms of basic structure, computers can be divided into five major parts: operator, memory, controller, input device and output device. Next, we will uncover their mystery step by step.

What are the main parts of the computer's hardware system?

1. The basic composition of the computer hardware system (five major components): operator, controller, memory, input device and output device. Operators and controllers are collectively called central processing units (CPUs). Memory is divided into two categories: internal memory and external memory. CPU, internal memory and interfaces connecting input and output devices are collectively called host.

2. Computer hardware contains 5 important components: operator, controller, memory, input device and output device. Operator. The main function of the operator in computer hardware is to calculate and process data and information.

3. The basic parts that make up the computer hardware system are: operator, controller, memory, input device and output device. The computer hardware system is still composed of five parts: operator, controller, memory, input device and output device.

4. The computer hardware system consists of five parts: operator, controller, memory, input device and output device. The main function of the operator in the operator computer hardware is to calculate and process data and information. The operator includes the following parts: general register, state register, accumulator and key arithmetic logic units.

5. The main function of the operator is to perform various arithmetic and logical operations to process the data. Controllers, operators and registers, etc., which make up the core of the hardware system - Central Processing Unit (CPU). Memory Memory is a component of computer memory or temporary storage of data.

6. Computer hardware refers to the composition ofThe physical equipment of a computer, that is, a physical component composed of mechanical and electronic devices with input, storage, calculation, control and output functions.

Chapter 4 Memory Management Why configure hierarchical memory? This is because: a. Setting up multiple memories can make the hardware at both ends of the memory work in parallel. B. Adopt a multi-level storage system, especially Cache technology, which is the best structural scheme to reduce the impact of memory bandwidth on system performance.

Chapter 2 How many generations has the development of computers gone through? What are the logical parts or components of each generation?The development of computers has gone through four historical stages (four generations); the logical components or components of each generation are electron tubes, transistors, small and medium-sized integrated circuits, and ultra-large-scale integrated circuits.

I don't know the after-class exercises of computer system structure, please guide me

1. What is the relationship between the actual bandwidth of the main memory and the modulus m?The reason? When the instruction flow and the data flow are random, what is the relationship between the actual bandwidth of the main memory and the analog m? The actual bandwidth of the main memory increases with the increase of the modulus, but the increment will decrease. This is because the program will be transferred and the data distribution will be random.

2. Why is the interrupt priority generally from high to low: machine verification, procedural and management program call, external, I/O, restart? If the machine verification is not processed in time, the system will not work properly. Program interruptions that are lower than external and I/O interruptions may cause confusion. Only after dealing with the machine failure can the access control be interrupted.

3. Chapter 1 Basic Concepts of Computer System Structure 1 Explains the following terminology hierarchical mechanism: According to the order of computer language from low to advanced, the computer system is divided into multi-level hierarchical structures according to function, and each layer is characterized by a different language.
