    A motherboard, also known as a system board or mainboard, is a central component in a computer system. It acts as a hub that connects all the other parts of the computer together, including the CPU, memory, storage, and peripherals. The motherboard contains a variety of chips and components, such as the BIOS, which controls the basic input and output functions of the computer, and the chipset, which controls communication between the different components. The motherboard also has a number of connectors and ports that allow other components to be connected to it, such as USB ports, Ethernet ports, and audio jacks.

    What is a CPU and what does it do?

    A CPU, or central processing unit, is the “brain” of a computer. It is responsible for executing instructions and performing calculations. The CPU is a small, integrated circuit that is typically located on the motherboard, and it communicates with other components in the computer through a system bus. The CPU is also responsible for managing the computer’s memory, as well as controlling input and output operations.

    How does the motherboard connect to the CPU?

    The CPU is connected to the motherboard through a socket, which is a physical connector that allows the CPU to communicate with other components on the motherboard. The socket is designed to match the specific type of CPU that is being used, and it is typically located in the center of the motherboard. The CPU is inserted into the socket and then secured in place with a retention mechanism, such as a clip or lever. Once the CPU is securely in place, it can communicate with the rest of the components on the motherboard through the system bus.

    So essentially, a motherboard and a CPU are the two main components of a computer. While a motherboard acts as a hub that connects all the other parts of the computer together, a CPU is the “brain” of the computer, responsible for executing instructions and performing calculations.
