Introduction
“A CPU (central processing unit) is the “brain” of the computer; it follows the instructions of the software to manipulate data into information.” (Sawyer, 2010, p. 208) The CPU performs logic and arithmetic operations, controls instruction processing, and supervises the overall operation of the computer. The main components of the CPU are the CU (control unit) and the ALU (arithmetic/logic unit). (Dugger & Gerrish, 1994, p. 578) The CPU also has registers which temporary store data during processing, and buses that act as roadways which transmit bits of data within the CPU and to other components on the motherboard.
CPU: The control unit deciphers the instructions from the input and moves them into memory. For each instruction the CPU will fetch the instruction, decode the instruction, execute the instruction, and store the result. These four basic operations are known as a machine cycle. The control unit is therefore responsible in the CPU to instruct and control where the data goes to and what will happen to it. (Sawyer, 2010, p. 208)
ALU: The arithmetic/logic unit executes data that the control unit has sent to it. It performs basic arithmetic operations such
