RAM MEMORY SLOTS
RAM memory modules are plugged into these. These differ from other slots in that they include clips to hold the module in place
CHIPSET
Is a set of chips on the motherboard that carries out communications between the microprocessor and the different components connected to the motherboard. It controls the operating mode of the board and determines its performance and characteristics.
MICROPROCESSOR SOCKET
A thermal paste is added under the sink to improve heat dispersal and, finally, the microprocessor is located above the socket.
