I only have a cursory understanding of the CPU memory main hard disk graphics card, but I still don

The CPU is used for computing.

Memory is used to store temporary data (this data disappears when the power is off), and hard disk is used to store data such as data (it does not disappear when the power is off).

The graphics card is for processing images.

A discrete graphics card is a discrete graphics card, because the motherboard generally has an integrated graphics card, and the CPU also has a core graphics card, and the discrete graphics card is additionally plugged into the motherboard (because the discrete graphics card is generally more than the integrated graphics card core graphics card).

Single-core dual-core: To take an analogy, the CPU is like a carriage, single-core is a horse pulling, and dual-core is two horses pulling, so dual-core is faster than single-core.

The CPU, the processor, is responsible for all the computing on your computer. Memory, temporary storage of data transmitted by CPU, graphics card and other devices, because the CPU computing speed is too fast, your hard disk or other devices can't keep up, so memory is needed to alleviate the rate mismatch. Hard disk, physical memory used to save data after a power outage.

Graphics card, auxiliary CPU processing graphics image data, processing graphics image data requires too many operations, relying on the CPU to process the load is too large, relying on the graphics card to help the CPU to share part of the data processing, which will greatly improve the running speed of the CPU.

Landlord, let me make a long story and say that the CPU is the brain of the computer, which is responsible for processing all kinds of data. The hard disk is a storage device, which stores all kinds of files, applications and other data in the computer, and it will not disappear when it is shut down. Memory is used to store all kinds of temporary data for the CPU and applications, and the shutdown disappears.

The graphics card processes and outputs the image, and the image on the screen is what the graphics card processes and outputs. These four parts complement each other and are indispensable for a computer to work. If you don't understand, you can ask

1. CPU: ** processor is a super-large-scale integrated circuit, with many pins, is the core of the computer, it is the core of the computer for computing and control, processing all kinds of information operations, just like people calculate math problems with their minds.

2. Memory: Memory generally refers to the semiconductor storage unit that stores data and instructions in the computer system, which can be divided into main memory and auxiliary memory according to its purpose. It is the place where the computer is usually opened to run programs, and the programs in the computer are run in memory (such as the system, open word, listening, etc.).

3. Graphics card: It is the control circuit and interface for the communication between the display and the host, and its function is to convert the digital signal of the host into an analog signal and display it on the monitor. The basic role of the graphics card is to control the output of the graphics.

4. Hard disk: hard disk is a fixed storage device, its storage medium is a number of rigid disk pieces, its characteristics: fast speed, large capacity, high reliability, almost no wear and tear problem, usually open files, created files, ** things and so on are stored on this hardware.

CPU computer heart processing data operation memory cache data easy to call graphics card display graphical interface support image stream linear hard disk warehouse storage data all hand-made ......

The CPU is the heartbeat of the processor, the core, the heart. Graphics. It's an excuse for the display to connect to the data, and the reality of the graphics card is good, and the display speed is fast. The premise is that the display is a good hard drive. A place to store things, think about people's stomachs, and hold things

The CPU is the ** processor, and the BAI is the DU that processes all the data of the computer. Memoryzhan is an internal buffer.

DAO deposits.

It is a genus that is dumped from the hard disk to the CPU to be processed.

of the data. The graphics card is a display card, which converts the data processed by the computer into an image signal so that it can be sent to the display screen. The hard disk is the main storage device of the computer, and all the data is stored in the hard disk, including the system, programs and personal data.

CPU ** processor, the heart of the computer, is used to process data operations, control the operation of the computer, memory, cache, call data, graphics card, processing interface graphic image display, support flow linear, hard disk, equivalent to warehouse, used for data storage and use.

CPU is equivalent to the brain of the BAI computer, which is the center of the computer to process data and programs, and the performance of the DAOCPU almost determines the performance of the computer. Memory is colloquially said to be "computer internal memory", is the internal equipment of the computer, its role can be said to be "what you see on the monitor, all the work that the computer is processing must be read into the memory", so it is also an important performance indicator of the computer, the data in the memory will disappear after the power is off; The graphics card is the hardware device of the computer, our monitor wants to display the image to transmit data from the computer to the display, the graphics card plays this role, of course, in the process of use, the graphics card driver is also needed, that is, the hardware and software support the display at the same time to work; Hard disk is a kind of external memory, hard disk is used to store data, our system, software, data, documents are stored in the hard disk, the data in the hard disk will not disappear when the power is off.

who is most important; It is tantamount to the important CPU of the human brain, heart, and liver: ** processor; The brain memory of a computer with the ability to calculate and process data: a temporary storage unit, that is, a temporary hard disk, has a great impact on the speed of the computer.

Especially some geodetic arithmetic.

Graphics. The display effect of the machine, large games must have a good graphics card.

Each part can only be different, the speed of the CPU is the fastest, and the speed of memory data processing can never keep up with the CPU, so the CPU is generally OK, and it is a waste to be very high, and the CPU we use cannot play all his performance at all.

Therefore, it is recommended that you choose a CPU of about 500 blocks that is completely sufficient. 1G memory is completely sufficient, and the graphics card is about 500 yuan, and the 7500GT level is also completely sufficient.

If you have any questions, you can continue to ask!

If the landlord says 3D games, CPU memory graphics card is equally important.

The CPU is the most important, and the computer does not have the CPU, and nothing else is important!

In general, it is the CPU, which is the core, which is the processing power of the computer.
