Introduction to the hardware of the computer, introduction to the various parts of the computer hard

The basic hardware configuration of the computer is as follows:

1. Motherboard: The main circuit system that makes up the computer is installed, generally including BIOS chips, IO control chips, key and panel control switch interfaces, indicator plug-ins, expansion slots, DC power supply connectors for the motherboard and plug-in cards, and other components. The type and grade of the motherboard determine the type and grade of the entire computer system, and the performance affects the performance of the entire computer system.

2. CPU: also known as ** processor, is an integrated circuit module, which is mainly used to interpret computer instructions and process data in computer software. The function of an instruction is often realized by the components in the computer to perform a series of operations, and the CPU should generate the corresponding operation control signal according to the function of the instruction and send it to the corresponding components, so as to control these components to act according to the requirements of the instruction.

3. Memory module: The memory module is used to temporarily store data, which is also inserted on the motherboard, and the CPU can be addressed through the bus and read and write computer parts. Any input and any output on the computer can only be made through memory.

The performance metrics of a memory module depend on the storage capacity, access speed (storage cycles), and the reliability of the memory.

4. Hard disk: It stores all the data information of the user, affects the running speed of the computer and the user's operating experience, as the data memory of the computer system, the capacity is the main parameter of the hard disk. The higher the rpm value, the faster the internal transfer rate, the shorter the access time, and the better the overall performance of the hard disk.

5. Monitor: It belongs to the computer IO equipment, that is, the input and output equipment. Usually two glass substrates are equipped with a alignment film, the liquid crystal will be aligned along the groove, under the action of different current electric fields, the liquid crystal molecules will be arranged in a regular rotation of 90 degrees, resulting in a difference in light transmittance, so that the difference between light and dark is produced under the action of power on and off, and each pixel can be controlled in this principle, and the required image can be formed.

Notebook several large hardware.

It mainly depends on the brand, frequency, and power consumption of the CPU, and there is no obvious difference between the daily operation of the mid-range and the high-end of the actual notebook CPU.

2.Memory, mainly depends on the capacity of the memory, frequency, and several generations of products, the larger the memory capacity within 4G, the more the running speed will be, and there is no obvious difference above 4G.

3.Graphics card, graphics card brand, video memory size, graphics card frequency, among which the graphics card brand and video memory size are more important, and the video memory 2G is enough to cope with all daily use.

4.Hard disks, hard disks are no longer a problem for today's notebooks, basically above 320, and it is also cheap to buy external hard disks.

The key is these four parts, others such as screen, fuselage design, keyboard, etc., depending on personal preferences, just pleasing to the eye; It should be noted that when looking at the laptop, you must touch the temperature of the laptop wrist rest and the keyboard surface with your hands, and the laptop with poor heat dissipation cannot afford to hurt.

That's all, I hope it can help you.

Look at the CPU model, memory size, hard disk size, graphics card model. Other ancillary stuff.
