What is the name of computer architecture

There are other types of computer architecture: macro architecture, assembly instruction set architecture, macro architecture visible to programmers, microcode instruction set architecture, etc. Some architectural definitions define them as describing computer functions and programming models, not specific implementations.

Von Neumann's structural computer hardware system consists of five parts (operator, controller, memory, input device, output device). This set of theories is called von Neumann architecture.

Computer architecture refers to a collection of a series of system elements properly organized together. These system elements cooperate with each other to achieve predefined goals through the processing of information.

The architecture of the computer refers to the overall structure of the computer, including the hardware and software composition of the computer, and the interrelationship between the parts. It is the core of the computer system, which determines the basic performance, function and operation mode of the computer.

What architecture is called by modern general-purpose computers? The introduction is as follows: Modern general-purpose computers are called von Neumann structure. Von Neumann was the first to put forward the idea of program storage and successfully applied it to the design of computers. Computers made according to this principle are called von Neumann structural computers.

ComputerArchitecture is the attributes of the computer that programmers see, that is, conceptual structure and functional characteristics. According to the multi-level hierarchy of the computer system, the computers seen by different levels of programmers have different attributes.

What is the definition of computer system structure

The more classic definition of computer system structure was proposed by Amdahl et al. in 1964: the genus of a computer system seen by programmers Nature, that is, conceptual structure and functional characteristics. Because computers have different hierarchical structures, the attributes of computers seen by programmers at different levels are obviously different.

Computer architecture refers to the general term for computer theoretical components and computer basic working principles and theories divided according to different attributes and functions. Computer Architecture is the attributes of the computer that programmers see, that is, conceptual structure and functional characteristics.

None of them, so what is it? The structure of the computer system is the external characteristics seen by the machine language programmer or compiler of the computer. The so-called external characteristics are the conceptual structure and functional characteristics of the computer.

System structure refers to the various components of a system and the relationship and interaction between them. Hardware composition Hardware is a physical part of the computer system, including the central processing unit (CPU), memory, hard drive, input and output devices, etc.

What are the five layers of the hierarchical structure of the computer system?

The hierarchical structure of the computer system is high-level language machine level, assembly language machine level, traditional machine language machine level, and microprogram machine level in order from high to low. The computer system is hierarchical, and it is composed of a multi-level hierarchical structure.

The hierarchy of computer systems includes: hardware layer, operating system layer, system program layer, and application layer. The hardware layer provides basic computable resources, including processors, registers, memory, and various I/O facilities and devices, which are the basis for the work of operating systems and upper-level software.

Composition of computer system

1. The computer system is composed of: controller, operator, memory, input device and output device.Controller: the control system of the computer. The computer controller is the nerve center of the computer, which directs the automatic coordination of various parts of the whole machine.

2. Computer hardware: It is a general term for various computer parts and equipment composed of electronic, mechanical and photoelectric components in the computer system, and it is the material basis for computers to complete various tasks. It refers to the actual device in the computer system, which is the visible and tangible physical components that make up the computer. It is the "body" of the computer.

3. The computer system is composed of hardware system and software system. Hardware system: controller: is the central nerve of the whole computer. Its function is to interpret the control information specified by the program, control according to its requirements, schedule programs, data, addresses, coordinate the work of various parts of the computer and access to memory and peripherals, etc.

Hierarchy of computer system?

Operating system level --- Level 3 From the basic functions of the operating system, on the one hand, it directly manages the software and hardware resources in traditional machines, and on the other hand, it is an extension of traditional machines. Assembly language level --- Level 4 The programming tool of this level is an assembly language instruction set.

Hierarchy of computer system: hardware layer - operating system layer - language processor layer - application layer. The role of the operating system: improve the efficiency of the computer system, enhance the processing capacity of the system, give full play to the utilization rate of system resources, and facilitate users' use.

Divide the computer system into multi-level hierarchical structure according to functions.Series level Zero is the hard-link logic level, which is the kernel of the computer and is composed of gates, triggers and other logic circuits. Microprogram level The first level is the microprogram level.

The computer system is hierarchical, which is composed of a multi-level hierarchical structure. In terms of function, computer systems can be divided into five levels. The first level is the microprogram design level, also known as the hardware level; the second level is the general machine level, also known as the machine language level; and the third level is the operating system level, which is implemented by the operating system program.

Modern computer systems are divided into multi-level hierarchical structures according to their functions, namely hard logic level, microprogram level, traditional machine level, operating system level, assembly language level, advanced language level and applied language level. Using this grading perspective to design computers can ensure a good system structure.

Briely describe the architecture of the computer system

1. Single-processor architecture In a computer with graded storage, for a CPU, the key factor that determines the continuous memory bandwidth is the cache Hit the waiting time.

2. Computer architecture refers to a collection of a series of system elements properly organized together. These system elements cooperate with each other to achieve predefined goals through the processing of information. The system elements usually included are: computer software, computer hardware, personnel, databases, documents and processes.

3. Computer architecture refers to the logical organizational structure composed of computer hardware and software, which is the overall design scheme of the computer system.The architecture of a computer includes the hardware and software of the computer, and the relationship between them. The architecture of the computer determines the performance, reliability and maintainability of the computer system.

4. Computer architecture is a set of rules and methods that describe the functions, organization and implementation of a computer system. The discipline of computer architecture is divided into three main subcategories: instruction set architecture, microarchitecture, system design: including all other hardware components in the computing system.

5. The hierarchical structure of the computer system is: hardware layer, operating system layer, system program layer, and application layer. The hardware layer provides basic computability resources, including processors, registers, memory, and various I/O facilities and devices, which are the basis for the work of operating systems and upper-level software.

6. The architecture of the computer refers to the overall structure of the computer, including the hardware and software composition of the computer, and the interrelationship between the parts. It is the core of the computer system, which determines the basic performance, function and operation mode of the computer.
