The hardware configuration of a computer is a measure of the performance of a computer. It mainly depends on the CPU, graphics card, motherboard, memory, hard disk, monitor, etc.
custom mini pc，Today, I will introduce you to the basic knowledge of hardware.
1. CPU: CPU is the abbreviation of central processing unit. It is one of the main equipments of electronic computers and the core accessories in computers. Its function is mainly to interpret computer instructions and process data in computer software. The CPU is responsible for all operations in the computer to read instructions, decode and execute instructions, and is one of the core components of the computer.
2. Graphics card: The graphics card is also called a display adapter. The role of the graphics card is the computer's digital-to-analog signal conversion device, and it is responsible for the task of outputting and displaying graphics. It converts the computer's digital signal into an analog signal for the display to display. At the same time, the graphics card still has images. The processing power can assist the CPU to work and improve the overall operating speed.
3. Motherboard: The motherboard is equivalent to our heart, because all hardware needs to be connected to the motherboard. It connects electrical appliances with different voltages together, provides corresponding power, and connects electrical appliances with different functions. Together, they can transmit information to each other, and they can also receive external data and pass it to other devices for processing, and collect the data processed by the internal device and pass it to the outside world.
4. Memory: The memory is mainly used to temporarily store data. For example, the data called in the computer needs to be read from the hard disk, sent to the memory, and then the memory is sent to the CPU. It can also be understood as a cache between the memory and the CPU. .
5. Hard disk: The hard disk is the main storage medium of the computer. The hard disk is equivalent to the warehouse of the computer. The operating system, installed software, as well as documents, materials, etc., are all stored in the form of data (binary 0 and 1) in the "warehouse" "middle. Hard disks are mainly divided into three types: mechanical hard disk HHD, solid-state hard disk SSD, and hybrid hard disk.
