How many ways are there to make up a computer system using hardware? What is the definition of hardware?

1. How many methods are there to form a computer system?

The components of a computer system can be divided from different perspectives. There are mainly the following methods:

1. ##1.

   Divided by function: It is divided into functional components such as central processing unit, memory, input device, output device and controller.

2. 2.

   Divided by performance: It is divided into host and peripherals. The host includes the central processor and main memory, and the peripherals include input and output devices.

3. 3.

   Divided by architecture: It is divided into single-machine systems and multi-machine systems. Single-machine systems include personal computers, workstations, etc., and multi-machine systems include cluster systems, etc. .

4. 4.

   Divided by scale: Divided into mainframe computers, minicomputers, microcomputers, etc.

2. What is hardware?

In the computer field,

hardware refers to the physical part of the computer system that can be seen and touched and can directly participate in data calculation and processing, including central processing unit, memory, hard disk, Various physical devices such as monitors, keyboards, mice, etc.

Hardware is the physical foundation of the computer system and is responsible for performing the actual operations of the computer, receiving and processing data, and controlling the work of various devices. It consists of various components, including central processing unit (CPU), memory, input and output devices, etc.

3. What is software?

Software is a set of instructions and data in a computer system that instructs the computer how to perform tasks. It includes software systems such as operating systems, applications, and programming languages.

Software is the non-physical part that controls the work of hardware. It enables the hardware to complete various tasks, provides a user interface, and manages the computer's resources.

4. What is a computer hardware system?

Computer hardware system refers to the physical components of a computer, including central processing unit, memory, input and output devices, storage devices, etc. Hardware systems execute computer programs and perform data processing and storage.

The performance and functions of the hardware system directly affect the running speed and capabilities of the computer.

5. What is a computer software system?

Computer software system refers to a collection of various computer programs, data and documents, including operating systems, applications, programming languages, database systems, etc.

The software system exists to facilitate users to use the hardware system. It enables the hardware to complete various tasks more efficiently and flexibly.

6. What are the three categories of computers?

Computers can be divided into three categories:

1. 1.

   Supercomputer: Used to handle large-scale scientific and engineering computing tasks, It has extremely high computing speed and processing power.

2. 2.

   Large computer: Usually used for information processing in large enterprises and institutions, with strong processing power and storage capacity.

3. 3.

   Microcomputer (personal computer): Mainly used in personal or small office environments, including desktops and laptops.

7. Briefly describe the relationship between the computer software system and hardware system?

There is a close relationship between the computer software system and the hardware system. The two complement each other and together form a complete computer system.

1. (1)

   The role of the hardware system: Provides the physical basis for computer operation, including central processing unit, memory, input and output devices, etc. Hardware executes software instructions to implement calculations and data processing.

2. (2)

   The role of the software system: Control the work of the hardware to complete various tasks. Software includes operating systems, applications, etc., which provide users with a friendly interface, manage hardware resources, and implement various functions.

3. (3)

   Interdependence: Software needs the support of hardware to execute, and hardware needs the control of software to work properly. The synergy between the two enables computers to complete a variety of complex tasks.

Summary

The computer system includes a hardware system and a software system. The hardware provides an execution environment for the software, and the software controls the work of the hardware. Computers are divided into supercomputers, mainframe computers and microcomputers. Hardware systems and software systems are interdependent and together constitute a complete computer system.
