Study Notes
CPU (Central Processing Unit)
- Also known as processor, central processor, or microprocessor
- Carries out all important functions of a computer
- Consists of three components:
- ALU (Arithmetic Logic Unit)
- Control Unit
- Memory or Storage Unit
- Enables communication between input and output devices
- Referred to as the brain of the computer
Secondary Memory
- Accessed indirectly via input/output operations
- Non-volatile, permanently stores data even when the computer is turned off
- Examples of secondary memory (not mentioned in the text)
