CPU

Central Processing Unit (CPU).

            The microprocessor also called the Central Processing Unit. Interprets and carries out all the basic instructions that operate the computer

Central Processor Unit

Processor contains a control Unit (CU) and an Arithmetic and Logic Unit (ALU) These are two components work together to perform processing of operations.

Control Unit (CU)

                   

                       The control unit is the component of the processor that directs a coordinates most of operations in the computer. The control unit has a rule to much like a traffic cops. It interprets each instruction issued by a program and then initiates the appropriate action to carry out the instructions.

Arithmetic Logic Unit

                       The Arithmetic Logic Unit (ALU) another component of the processor performs arithmetic, comparison, and logical operation. Arithmetic operations include basic calculations such as addition, subtraction, multiplication and division. Logical operation include conditions along with logical operator such as AND, OR, and NOT for Example, if only employees paid hourly can receive overtime pay, the ALU must verify to condition before computing an overtime wage.

1.      The employee is paid hourly AND.

2.      The employee worked more than 40 hours.
