Across
  1. 5. Non volatile, read only memory that stores the boot up and BIOS
  2. 8. High speed,volatile memory that stores data and instructions
  3. 11. memory stored outside the computer when not in use, e.g. CDs/SSD
  4. 13. memory stored inside the CPU, e.g. RAM/ROM
  5. 14. cheap, slow secondary storage with the lowest capacity e.g. CD
  6. 17. fast access memory when the RAM is full
Down
  1. 1. Secondary storage - extra RAM when the RAM is full
  2. 2. holds the results of calculations performed by the ALU
  3. 3. Fast, reliable, portable, and expensive secondary storage e.g. SSD
  4. 4. Controls the flow of data by sending signals
  5. 6. An extra CPU that independently processes data and instructions
  6. 7. Secondary storage with a large capacity and moving parts e.g. HDD. Appropriate for long term data backup
  7. 8. super fast memory that temporarily holds data inside cpu
  8. 9. Holds the current data and instructions to be written to memory
  9. 10. The amount of cycles performed in a second - effects performance of the CPU
  10. 12. Performs calculations inside the CPU
  11. 13. holds the address of the next instruction to be written to memory
  12. 15. Processes data and instructions
  13. 16. Holds the address of the current data and instructions to be written to memory
