Across
  1. 6. The part of the CPU where all mathematical calculations and logical comparisons are made.
  2. 8. Holds the specific current instruction ready to be decoded and executed after retrieval.
  3. 11. Stores all programs and data temporarily while in use for quick CPU access.
  4. 12. Measured in Hertz (Hz), this is the number of cycles a CPU can perform per second.
  5. 14. The final stage of the cycle where the CPU actually carries out the instruction.
  6. 15. A complete copy of a CPU; having more of these allows for better multitasking.
  7. 17. A register in the ALU that stores the intermediate results of calculations.
  8. 18. High-speed memory inside the CPU that stores frequently used instructions to speed up processing.
  9. 19. The "manager" of the CPU that decodes instructions and coordinates how data moves.
Down
  1. 1. This register holds the memory address of the next instruction to be fetched.
  2. 2. A tiny, super-fast storage location inside the CPU used for a specific purpose during the fetch-execute cycle.
  3. 3. The main component that processes instructions and manages hardware.
  4. 4. The stage where the Control Unit works out what the instruction actually means.
  5. 5. The register that holds the memory address of the current instruction or data being accessed.
  6. 7. A physical pathway (like a high-speed wire) used to transfer data between the CPU and memory.
  7. 9. The first stage of the CPU cycle where an instruction is moved from RAM into the CPU.
  8. 10. The process of making a CPU run at a higher clock speed than it was designed for (risking overheating).
  9. 13. The unit of measurement for CPU clock speed (e.g., Gigahertz).
  10. 16. The register that holds the actual data or instruction that has been fetched from or is waiting to be sent to RAM.
