The structure of the motherboard of a computer, laptop, server. Why do you need a motherboard? Three main tasks that the motherboard performs: communication, power, control. To connect the components on the motherboard, there are a lot of connectors: a socket for the processor, connectors for RAM, PCI-E, PCI, SATA, and so on. Also, for communication, the board is made multilayer. For the same purposes, there are bridges on the motherboard, or a chipset. How does the motherboard provide power to all these devices? For this, there are a lot of PWM controllers, some can be multiphase. They form all the necessary supply voltages. What is the multicontroller for? But it is precisely this that manages all the components. From their primary initialization at system startup to disconnection when the computer is turned off. It also monitors the temperature, monitors the reset and power buttons. In addition, the board usually has some peripherals in the form of a network card, a sound card, and so on. In general, briefly about the structure of the motherboard and the components of the motherboard and their purpose.
