The motherboard carries the CPU (i.e. central processing unit), memory (random access memory) and slots for expansion cards (but the CPU and memory are not integrated On the motherboard, it is not an accessory to the motherboard, but also belongs to the computer hardware itself) The motherboard is also called the mainboard, systemboard or motherboard; it is installed in the chassis and is the most basic and most basic part of the microcomputer. One of the important parts.
The motherboard is generally a 4-6 layer rectangular circuit board, on which are installed the main circuit systems that make up the computer. Generally, there are north and south bridge chips (some north and south bridges are integrated together) BIOS chip, I/O control chip, Keyboard and panel control switch interfaces, indicator light connectors, expansion slots, DC power supply connectors for motherboards and plug-in cards, and other components.
Memory is one of the important components in the computer. It is the bridge that communicates with the CPU. All programs in the computer run in the memory, so the performance of the memory has a great impact on the computer. Memory is also called internal memory. Its function is to temporarily store operation data in the CPU and exchange data with external memories such as hard disks. As long as the computer is running, the CPU will transfer the data that needs to be calculated into the memory for calculation. When the calculation is completed, the CPU will send the results out. The operation of the memory also determines the stable operation of the computer. Memory is composed of memory chips, circuit boards, gold fingers and other parts.
