What is the connector that interfaces between the motherboard and the processor?

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).
