What is the CPU?
What is the CPU?
The central processing unit (CPU) is the brain of a computer. It processes instructions and data, allowing the computer to perform actions. Think of it as the computer's control center.
What does the ALU do?
What does the ALU do?
The ALU performs mathematical calculations (like addition, subtraction) and logical comparisons (like comparing two numbers).
What does the Control Unit do?
What does the Control Unit do?
The Control Unit coordinates all the CPU's operations and tells the other components what to do. Think of it as the CPU's traffic cop.

Study Notes
CPU Components
- The Central Processing Unit (CPU) is a key component responsible for processing data and instructions.
- The CPU accepts input from devices (e.g., keyboard, mouse) and delivers output to devices (e.g., monitor, speakers).
- The CPU's internal components include the Arithmetic Logic Unit (ALU) and the Control Unit.
- The ALU performs calculations and logical operations.
- The Control Unit coordinates CPU operations and manages data movement.
- Cache is high-speed storage within the CPU for frequent data/instruction access.
- The Clock synchronizes CPU operations with regular pulse signals.
- Registers are high-speed CPU memory locations with specific functions.
- Buses are wire groups, facilitating communication between components.
- Address Bus: Carries addresses for memory access.
- Data Bus: Transmits data/instructions in binary.
- Control Bus: Facilitates communication and control signals.
Key CPU Registers
- The Program Counter (PC) stores the address of the next instruction.
- The Memory Address Register (MAR) holds the memory address of required data/instructions.
- The Memory Data Register (MDR) temporarily stores data from/to memory.
- The Accumulator is a general-purpose register for temporary values during processing.
