Today we discussed the CPU. The CPUJ which is called the Central Processing Unit comes in two forms, the PGA (Pin Grid Array) and the LGA (Land Grid Array). When you see a PGA CPU the when you turn it upside down you will look right ate the pins underneath it, but when you look at a LGA CPU, when you turn it upside down you will see holes. The pins would be located on the motherboard right where the CPU is suppose to go. The CPU can be easily identified by seeing a heat sink near it which would look like 4 small rows of metal and a fan will be sitting on top of the CPU. The CPU is located on the motherboard co every computer has one.
