CPU is an acronym for central processing unit. Often described as the brain of a computer, the central processing unit manages all of the information relayed by the software and hardware connected to the computer.
The central processing unit is a computer chip, typically square or rectangular in shape, which is connected to the motherboard of a computer. The main parts that comprise the CPU are the control unit and the arithmetic logic unit. The control unit reads and deciphers coded information and the arithmetic logic unit executes mathematical and logical operations based on the information sent from the control unit.
