The central processing unit (CPU) is plugged into the motherboard. Everything else in the computer is directly or indirectly plugged into the motherboard. There are expansion boards, for instance, which have all kinds of processors on them, but they are plugged into the motherboard meaning it is the base board that everything ultimately connects to, like the foundation of a house.
This creates a connection from everything to the CPU. This is necessary because the CPU, like the motherboard, is central to the control of the computer as a whole. It ultimately controls the lowest level functions of the operating system and actually controls most things that happen in a computer. Actually, more than saying control, it is most of the work of the computer. It does the numeric operations that are what a computer, for the most part, does.
CPU = brains, motherboard = connections to the periphery
cpu
The connector that interfaces between the motherboard and the processor is called the CPU socket. This socket serves as a physical and electrical interface, allowing the processor to communicate with the motherboard and other components. Different CPU sockets are designed for specific processor architectures, ensuring compatibility between the motherboard and the CPU. Examples of popular CPU socket types include LGA (Land Grid Array) and PGA (Pin Grid Array).
Motherboard
Processors don't connect to a motherboard, there are installed in a socket. What determines if a processor is compatible is the type of processor... PGA(AMD most of the time) or LGA(Intel) and the ammount of pins that are on the motherboard/processor.
engaged
The heat sink absorbs the heat from the processor and then the fan disperses the heat.
function of the processor is to process data
The processor socket is both a technical convention and functional component. As a convention Socket # such as 775 and 1150 regard motherboard chip type compatibility. The functional aspects of the socket serve as the electrical interface between the motherboard (and its peripherals) to the processor itself.

processor
No, a processor is not fixed to the motherboard. Most modern processors are designed to be easily removable and replaceable using a socket on the motherboard. This allows for easy upgrades or replacements without replacing the entire motherboard.
A motherboard can support one processor only.
