Socket 370 processor socket
The term CPU socket (or CPU slot) is widely used to describe the connector linking the motherboard to the CPU(s) in certain types of desktop and server computers, particularly those compatible with the Intel x86 architecture.
Most CPU sockets and processors in use today are built around the pin grid array (PGA) architecture, in which the pins on the underside of the processor are inserted into the socket, usually with zero insertion force (ZIF) to aid installation. In contrast to this, several current and upcoming sockets use a land grid array (LGA) in which the pins are on the socket side instead and come in contact with pads on the processor. Slot based processors are cartridge shaped and fix into a slot that looks similar to expansion slots.

1: The 478 pin socket was introduced because it uses a micro-PGA layout which is physically smaller than the socket 423. Socket 775 was introduced with support for PCI express, DDR2 memory and Intel's version of the AMD64 processor extensions (called EM64T), but also moved to the new Land Grid Array physical layout, where the pins are in the socket rather than on the CPU package, for better electrical performance.
2: These sockets are for CPUs with integrated memory controllers. The 754 pin models have a single memory channel routed through the CPU pins. The 939 pin models have two memory channels, hence the higher pin count. The 940 pin CPUs also have two memory channels but they require registered memory, and most have support for SMP. Sockets F and AM2 are redesigned to support DDR2. The Socket F contains 1207 pins (Added pins speculated to be for more scalability and better power distribution. Socket AM2 has 940 pin-holes but does not support current AMD Opteron processors.
3: The slot packages had two advantages; L2 cache could be installed on the processor package but on a separate piece of silicon, and insertion and removal is simpler and easier. However, it lengthens the path of the traces from the CPU to the chipset and so became unsuitable as clock speeds increased past around 500 MHz. They were therefore abandoned and replaced with Socket A/Socket 370.CPU socket
