(Image credit: Mastermilmar/Shutterstock)

A PC’s socket is made up of a series of pins and connects a CPU’s processor to the PC’s motherboard. If a CPU is connected via a CPU socket, it is not soldered and can be replaced. These are more common on desktops than they are on laptops. Not all types of CPUs are compatible with all types of sockets.
