Study Notes
Central Processing Unit (CPU)
- The CPU is the microprocessor at the core of a computer system.
- Functions as the brain of the computer, processing digital data for various tasks.
- Composed of three essential parts: the control unit, arithmetic and logic unit (ALU), and clock.
Control Unit
- Manages and orchestrates tasks performed by the CPU.
- Interprets incoming instructions to determine their meaning.
- Coordinates operations by directing other CPU components to execute tasks based on the processed instructions.
Arithmetic and Logic Unit (ALU)
- Responsible for performing all calculations within the CPU.
- Operates similarly to software tools like spreadsheets for mathematical problems.
- Receives instructions from the control unit to execute various arithmetic and logical operations.
Clock
- Generates regular electrical pulses to synchronize CPU operations.
- Tick frequency is approximately 3 billion times per second, far exceeding a household clock.
- Each clock tick prompts the control unit to send an instruction to the ALU, ensuring continuous operation and processing of tasks.
