The Central Proccessing Unit
The word computer refers to the central proccessing unit (CPU) together with an internal memory. The internal memory or main storage, control and proccessing components make up the heart of the computer system.
In digital computer, the CPU can be divided into two functional units called the control unit (CU) and the arithmetic-logical unit (ALU). These two units are made up of electronic circuits with millions of switches that can be in one of two states, either on or off.
The function of the CU within the central processor is to transit coordinating control signals and commands. The CU directs the sequence or step-by-step operation of the system, select intructions and data from memory, interprets the program instruction, and controls the flow between main storage and the ALU.
The ALU is part of computer in which the actual arithmetic operations are performed. It also performs some kinds of logical operation such as comparing or selecting information. All the operations of the ALU are under the direction of the CU.
