Additional Information
- The Arithmetic Logic Unit (ALU) is a core component of the CPU responsible for performing arithmetic and logical operations.
- The Control Unit (CU) directs the operation of the processor by telling the computer's memory, ALU, and input/output devices how to respond to the instructions that have been sent to the processor.
- Cache Memory is a small-sized type of volatile computer memory that provides high-speed data access to the CPU and improves processing speed.
- Unlike the hard disk, these components work together within the CPU to execute instructions and process data efficiently.
