Problem description: The role of the accessories in the help computer. The more the merrier.

Such as graphics cards, motherboards, sound cards, memory, hard disks, etc.

Analysis: The specific functions and characteristics of each computer accessory are very long, so let's briefly introduce them first.

The main accessories of a personal desktop computer are:

1.Motherboard: also known as motherboard, is the most important and basic carrier for connecting CPU, memory, AGP and other computer accessories, the structure type of the motherboard determines the structure and type of each computer accessory, and the motherboard BIOS and chipset play a key role in the overall function of the computer.

At present, the main types of motherboards are ATX and Micro ATX.

It is said that it is the heart of the computer, and some people compare it to a car-like engine.

3.Graphics card: The display data in the computer is processed and stored through the GPU and video memory of Mengyin in the graphics card, and converted into optical signals and displayed through the display connected to the graphics card.

4.Memory: It is the abbreviation of internal memory, which is used to store the data to be used at present, and the characteristic sock car is that the storage speed is fast and the storage capacity is small. Usually, CPU operations require reading programs and data from memory, and then returning the results to memory after computation.

5.Hard disk: It is also used to store programs and data memory, it is slow compared with memory, but the storage capacity is very large, it and memory to better solve the capacity and speed contradiction in storage, all kinds of programs and data will be stored in the hard disk, if you want to participate in the operation and calculation, the part that participates in the operation will be transferred to the memory, make full use of the memory storage speed of the characteristics, speed up the system running speed.

6.Sound card: Converts the digital signal of the sound in the computer into analog sound, which is the sound that we humans can hear.

The computer is a kind of optical storage device, it can read out the things on the disc that stores more data, it is a device that ***** discs, a simple ***** can not be burned, and the recorder is a device that can write data to a blank disc, it can not only burn, but also **.

The so-called hardware system refers to the physical equipment that constitutes a computer, that is, the physical parts with computing, control, storage, input and output functions composed of mechanical, optical, electrical, and magnetic devices.

A hardware system is a general term for the various electronic component entities that make up an electronic computer.

The hardware system is divided into processors, input devices, output devices, and storage devices. Among them, the processor includes a combinator and a controller, which is the core component of the computer, and the CPU accesses the data in the memory by address; Input devices include keyboards, mice, scanners, digital cameras, card readers, etc.; Output devices include monitors, printers, plotters, etc.; Storage devices are divided into internal memory and external memory, generally including memory, floppy disks, optical discs, hard disks, electronic disks, etc., and the main task of memory management is to solve the allocation of storage space.

Quite simply, a computer is hardware except for the software.

There is a peculiarity to these. It's basically all software.

Computer application is development, and programming is the creation of software.

Computer network technology is design, web design, and network building.

Computer information management is relatively wide, first of all, preliminary programming, preliminary design, and then mainly a variety of office software in the office to be proficient, do **ah**ah, more** these. ,But I will also get printers and those things.,But if you don't dig deeper.,There's nothing -- you can dig deep.。。。

Computer electronics technology is the technology of computers and peripherals, training with intelligent electronic product design, quality inspection, production management, can be in the field and department of electronic product design and development, quality inspection, production management, intelligent electronic products sales and technical support skills application - computer technology I put it bluntly, is to repair TV or something... Those people learned.

If you want me to recommend, I recommend information management, which is more developed in many aspects.

1 is the application of office software.
