1. Control Unit: The control unit is responsible for controlling the operations of the computer system. It manages the flow of data and instructions within the system, ensuring that they are executed in the correct sequence. The control unit fetches instructions from memory, decodes them, and then executes them. It also coordinates the activities of the other components of the computer system.
2. Arithmetic Unit: The arithmetic unit is responsible for performing arithmetic operations such as addition, subtraction, multiplication, and division. It also handles mathematical functions like square roots and exponentiation. The arithmetic unit operates on data that is stored in the computer's memory or registers, performing calculations according to the instructions provided by the control unit.
3. Logic Unit: The logic unit, also known as the logic and arithmetic unit (ALU), is responsible for performing logical operations such as AND, OR, NOT, and XOR. It compares data and makes decisions based on the results of these comparisons. The logic unit is an essential component of the computer system, as it is used in tasks such as data processing, decision-making, and control flow.
In summary, the control unit manages the flow of data and instructions, the arithmetic unit performs arithmetic operations, and the logic unit performs logical operations. Together, these components work together to execute programs and perform tasks on a computer system.
