This is the manipulating part of the CPU, Where actual data processing occurs. All calculations and comparisons take place in this section. The data and instructions, stored in the primary storage prior to processing and transferred as and when needed to the ALU where processing takes place. No processing is done in the primary storage unit. Intermediate results generated in the ALU are temporarily transferred back to the primary storage until needed at a later time. Data may thus move from primary storage to ALU and back again to storage many times before the processing is over ALU are designed to perform the four basic arithmetic operations add, subtract, multiply, divide, and logical operations or comparisons such as less than, equal to, or greater than. Because of these calculations and comparisons ALU is called the accountant of the computer. Ater the completion of processing, the final results which are stored in the storage unit are released to an output device. Decision making capabilities of the computer is achieved by capacity of ALU.

The function of the control unit is to supervise, monitor, coordinateds, control, and manage the various operations of a digital system. The control unit directs and coordinates the entire computer system in carrying out program instructions. It does not execute the instructions itself but instead directs other parts of the computer system to do so. The control unit supervises the flow of information between various units. It regulates the operations of the computer and enables it to communicate with operator and other devices in the system. Control unit acts as a central nervous system for other data manipulating components of computer. We can relate CU to the brain of the human body. It is the brain which control the whole body, we perform work with our hands, we walk with our feet, we can see with our eyes, we can hear with ears, but all devices are controlled by brain (CU).

The data and instructions that are entered into the computer system through input unit have to be stored inside the computer before the actual processing starts. Similarly, the results produced by the computer after processing must also be kept somewhere inside the computer memory before being passed on to the output units. The storage unit or the primary storage of a computer system is designed to provide all these needs. It provides space for storing data and instructions, space for intermediate results, and also space for the final results. The storage unit performs following functions:
  • Stores all the data to be processed and the instructions required for processing (receive from input devices)
  • Stores intermediate results of processing
  • Stores final results of processing before these results released to an output device
