What is the purpose of the CPU?
• Executes instructions
• Runs programs
What does the ALU do?
• Performs calculations
• Performs logic operations
What does the Control Unit do?
• Controls the fetch-execute cycle
• Sends control signals to other components
What is cache?
• Small, fast memory on the CPU
• Stores frequently used data and instructions
What are registers?
• Small, fast storage locations inside the CPU
• Hold data temporarily during processing
What is the difference between cache and registers?
• Cache stores frequently used data and instructions
• Registers hold small amounts of data being used right now
Why is cache useful?
• The CPU can access it faster than main memory
Why are registers useful?
• They are very fast
• They help the CPU process data quickly
What is the difference between data and an address?
• Data is the value or instruction
• An address is the memory location
What are the main CPU parts you must know?
• ALU
• Control Unit
• Cache
• Registers
