What determines the type of Central Processing Unit (CPU) that can be installed on a motherboard?

The type of Central Processing Unit (CPU) that can be installed on a motherboard is determined by the socket. The socket is a physical interface on the motherboard that holds the CPU in place and provides the electrical contacts necessary for communication between the CPU and the motherboard's components. Each CPU model is designed to fit a specific socket type, which means that the socket must match the CPU for them to be compatible.

While the chipset, RAM, and power supply unit contribute to the overall functionality and performance of a computer, they do not dictate which CPU can be installed. The chipset controls communication between the CPU and other components but is only compatible with certain CPUs based on the socket type. RAM specifications pertain to memory compatibility and the power supply unit relates to power distribution, but neither directly influences the physical connection and compatibility of the CPU to the motherboard.
