About the role or influence of various hardware devices of the computer

The CPU processes the data! Memory assists the CPU, and the graphics card processes the picture!

You're asking too generally! Not good! Please elaborate.

The hardware system consists of a processor, memory, and input and output devices.

1. The processor (CPU) can be divided into two parts: combinator and controller.

The function of the combinator is to perform arithmetic or logical operations, and it is a component that processes and calculates information or data.

The controller is mainly used to realize the automation of the running process of the computer itself, that is, to realize the automatic execution of the program.

2. The memory is used to store programs and data, and is the storage and communication center of various information of the computer.

3. Input device: a program used to input raw data and process these data.

Output device: Used to output the processing results of the computer.

Analysis: CPU is the first processor, it is the brain of the computer, and the computing and control of the computer are processed by it. (1) Controller:

The controller is the command center of the whole computer, which takes out the control information in the program, and after analysis, it sends out the operation control signal as required, so that all parts work in harmony.

2) Combinator: The combinator is an "information processing factory". The computation and processing of the data takes place in the combinator. The "operation" here is not only basic arithmetic operations such as addition, subtraction, multiplication, and division, but also includes some basic logical operations.

Memory plays a pivotal role in a computer, and memory is another criterion that can indicate whether a computer is of sufficient grade in addition to the CPU. Memory is a broad concept of semiconductor memory units that store data and instructions, including RAM (random access memory), ROM (read-only memory) and cache. RAM and ROM are both data storage.

RAM is random access memory, which is characterized by volatility, i.e., amnesia in the event of a power loss. ROM usually refers to solidified memory (write once, read repeatedly), which is the opposite of RAM. ROMs are available in two types: one-time curing, photoerasure, and electrical erase rewriting.

The motherboard is one of the most important parts of a computer and is the basis for the entire computer to work. The motherboard is composed of the following parts: CPU slot [socket], memory slot, cache, LAN bus and expansion bus, hard disk, floppy drive, serial port, parallel port and other peripheral interface clocks and CMOS motherboard BIOS control chip.

A display adapter card is an interface card that connects the host computer to the display. Its function is to convert the output information of the host computer into characters, graphics, colors, and other information, and transmit it to the display for display.

An input device is a device that converts data, information, and programs into electrical signals through computer interface circuits and sends them sequentially into computer memory for processing. Commonly used input devices are: keyboard, mouse, graphic scanners, card input machines, etc. as input devices, and the role of the mouse is getting bigger and bigger, even surpassing the keyboard.

Computer hardware: A general term for various physical devices in a computer system.

Hard disk, memory, graphics card, network card, optical drive, keyboard, mouse, sound card, motherboard, CPU, power supply, monitor.

Three major parts: CPU, graphics card, motherboard.

CPU operation data, is the data you input through the keyboard, mouse device, for example, you want to find a ** in the hard disk, first enter the device to issue instructions, the CPU receives the instructions you send, will find what you want in the hard disk according to your instructions, it can be what you are looking for**, but the computer does not recognize your instructions, then this is said to use the CPU operation, you input the **, the CPU will calculate it into the data that the computer can identify 0 and 1, and you used to exist in the hard disk ** It is also calculated as 0 and 1 and stored in the hard disk, and the hard disk will be assigned a unique address to it when storing this ** (in fact, the storage is not **, but **data calculated by the CPU), and it can be easily found through the CPU controller, because it has a unique address.

The motherboard, which can be said to be an interface board, has a very plugged in on it, and this plug is used to plug in our hard disk, memory, graphics card, network card, optical drive, keyboard, mouse, sound card, CPU, etc., these things must be plugged into the motherboard to interact, through the motherboard's BIOS to control these devices.

What about memory? Memory can be said to be the bridge between the CPU and the hard disk data exchange, in fact, the data obtained by the CPU is not directly read from the hard disk, it calls the data through the memory, when the power is powered on, the hard disk begins to work, and the data on the hard disk is continuously transmitted from the hard disk, because the data stored by the hard disk is a lot of hundreds of G, and the memory is only 1, 2G, so the data it transmits is the most important data of the user, if the CPU cannot find the desired data in the hard disk, it will find it from the hard disk.

What about graphics cards? You give a command, the CPU finds the information you want, and then outputs, where does the output go? To your display, what is it to show this data? Graphics? Yes, graphics accelerators.

These are the three that matter.

Generally speaking, there are two kinds:

1.Standalone sound card, graphics card, network card, hard disk, memory module, optical drive, keyboard, mouse, motherboard, CPU, power supply, monitor, soft area, etc.

2.The motherboard integrates a sound card, a graphics card, and a network card. This way you can only see hard drives, memory sticks, optical drives, keyboards, mice, motherboards, CPUs, power supplies, monitors, soft areas, etc.

Hard disk: Used to store files.

Memory: A cache of files while the computer is working on them.

Graphics card: Match the color of the display.

Network card: Internet access.

Optical drive: Read or burn discs.

Keyboard: A tool to enter your information into your computer.

Mouse: Equivalent to a human hand.

Sound Card: Adjust the sound.

Motherboard: The main part of a computer is the equivalent of a person's home.

CPU: The heart of the computer, the core part of the file process.

Power supply: power supply, voltage stabilization.

Display: Converts analog signals into images that can be recognized by the human eye.

Soft Zone: Read floppy disks. Not now.

Processor, memory, output and input devices.

It is the most important processor of the computer and the core hardware. It is equivalent to the human brain, the stronger the CPU performance, the smarter the human brain, and the CPU can control all the hardware of the computer. 2.

The motherboard is quite similar to the human skeleton and is the carrier of the computer, and the larger the skeleton, the higher the human figure. 3.The power supply is the human heart, which can provide energy to the various hardware of the computer.

The stronger the heart, the more energy nutrients it has. 4.The hard drive is equivalent to a person's speed, strength and backpack.

The more powerful the hard drive, the faster it works, the more things you move, and the more things you store. 5.The memory is equivalent to the spaciousness of the road, the smoothness of work.

6.Graphics cards and monitors are the equivalent of a person's field of vision, the eye. The stronger the graphics card and display, the farther we see, the clearer, and the more vivid the colors.

7.Sound cards and speakers are the equivalent of a person's throat and ears. The better the sound card, the more attractive the voice.

The better the horn, the clearer and more beautiful the sound we hear. 8.The chassis and heat dissipation are equivalent to the living and working environment of people, such as clothes, armor, houses, and the chassis protect the computer hardware, which is not susceptible to damage, and can also provide a comfortable environment and temperature for the computer.
