6. What is stored in RAM?

  • Programs and data that are currently in use by the CPU
  • Documents and files
  • Fixed programs and data that are currently in use by the CPU
  • Programs and files

7. What does RAM stand for?

  • Random Alternative Memory
  • Random Access Memory
  • Read Access Memory
  • Read Alternative Memory

8. Explain why programs do not run directly from secondary storage

  • Secondary storage can be removed from the computer
  • It is too slow for programs to run directly by the CPU
  • It is too small to store all the programs the CPU needs to run
  • It is too expensive

9. Explain why an embedded computer must store its program in ROM

  • So the contents are not lost when they are being altered
  • So the contents are not lost when the power is turned off and so the program cannot be altered
  • Because the contents need to be able to be altered
  • Because it is a dedicated computer system so it has a specific task

10. What does ROM stand for?

  • Random Offset memory
  • Read Often Memory
  • Read Only Memory
  • Random Only Memory

11. Is ROM volatile or non-volatile?

  • Non-volatile
  • Volatile

12. Describe how data is actually stored in ROM and RAM

  • Stored as binary numbers with a pattern of switches representing the binary
  • Stored as binary numbers with a pattern of switches in memory representing the binary numbers
  • Stored as binary numbers with a pattern of switches in memory
  • Stored as a pattern of switches representing the binary numbers

13. What does volatile mean?

  • Contents will be lost when the power turns off
  • Contents will not be lost when the power turns off

14. Is RAM volatile or non-volatile?

  • Volatile
  • Non-volatile

15. What is firmware?

  • An example of volatile software
  • Software to control hardware
  • An example of volatile hardware
  • Hardware to control software

16. What is meant by the term primary storage?

  • It is read/write storage.
  • Non-volatile (permanent) storage where all data is stored when not in use.
  • It is directly connected to the CPU and it is fast enough for programs to be run directly from it.
  • There is no direct connection to the CPU
