A computer system comprises several key operational units that work together to perform processing tasks efficiently. These operational units include the Arithmetic Logic Unit (ALU), Control Unit (CU), Memory Unit, Input Unit, and Output Unit. The Arithmetic Logic Unit (ALU) is responsible for performing arithmetic operations such as addition, subtraction, multiplication, and division. It also carries out logical operations like comparison, AND, OR, and NOT. The ALU is a crucial part of the Central Processing Unit (CPU) and plays a central role in data processing. The Control Unit (CU) manages and coordinates the activities of all parts of the computer. It interprets the instructions from programs and directs the operation of the ALU, memory, and input/output devices by sending control signals.
