6. What does ROM stand for?
- Random Only Memory
- Random Offset memory
- Read Only Memory
- Read Often Memory
7. Why would an embedded computer need RAM?
- To store data that needs to be changed
- So the contents are not lost when the power is turned off and so the program cannot be altered
8. Is ROM volatile or non-volatile?
9. How could increasing RAM increase what the OS can store?
- It can store more programs, bigger programs, more data and bigger data
- It can store more programs, bigger programs, more files and bigger files
- It can store more data, bigger data, more files and bigger files
10. What is meant by the term primary storage?
- It is directly connected to the CPU and it is fast enough for programs to be run directly from it.
- Non-volatile (permanent) storage where all data is stored when not in use.
- There is no direct connection to the CPU
- It is read/write storage.
11. Explain why programs do not run directly from secondary storage
- It is too slow for programs to run directly by the CPU
- Secondary storage can be removed from the computer
- It is too expensive
- It is too small to store all the programs the CPU needs to run
12. Explain the purpose of ROM in a computer system
- To store the programs and data needed to run a computer when there is no secondary storage so data is not lost when the power is turned off
- To store data and programs that the CPU is using while programs are running
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. Explain the purpose of RAM in a computer system
- Execute instructions
- Store data and programs that the CPU is using while programs are running
- Process instructions from the CPU
- Temporarily store instructions and data being used by the CPU
15. What is firmware?
- An example of volatile software
- Hardware to control software
- Software to control hardware
- An example of volatile hardware
16. Is RAM volatile or non-volatile?
