Basic Components of a Computer System
- A computer consists of hardware (physical components) and software (programs and applications).
- Hardware Components: Input unit, processing unit (CPU), storage unit, auxiliary storage, output unit.
-
Central Processing Unit (CPU): The computer's brain, controlling operations and memory, composed of:
- Arithmetic and Logic Unit (ALU): Performs calculations (addition, subtraction) and logical comparisons (greater than, less than).
- Control Unit (CU): Directs the sequence of operations and commands to other computer parts.
- Main Memory Unit holds data and instructions for processing.
