6. 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
7. Describe how data is actually stored in ROM and RAM
- Stored as binary numbers with a pattern of switches in memory representing the binary numbers
- Stored as a pattern of switches representing the binary numbers
- Stored as binary numbers with a pattern of switches in memory
- Stored as binary numbers with a pattern of switches representing the binary
8. What is meant by the term primary storage?
- There is no direct connection to the CPU
- It is read/write 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.
9. What is stored in RAM?
- Documents and files
- Fixed programs and data that are currently in use by the CPU
- Programs and data that are currently in use by the CPU
- Programs and files
10. Explain the purpose of RAM in a computer system
- Store data and programs that the CPU is using while programs are running
- Temporarily store instructions and data being used by the CPU
- Process instructions from the CPU
- Execute instructions
11. What is firmware?
- Software to control hardware
- Hardware to control software
- An example of volatile hardware
- An example of volatile software
12. Explain why programs do not run directly from secondary storage
- It is too slow for programs to run directly by the CPU
- It is too expensive
- It is too small to store all the programs the CPU needs to run
- Secondary storage can be removed from the computer
13. Explain why an embedded computer must store its program in ROM
- So the contents are not lost when the power is turned off and so the program cannot be altered
- Because it is a dedicated computer system so it has a specific task
- Because the contents need to be able to be altered
- So the contents are not lost when they are being altered
14. Is RAM volatile or non-volatile?
15. Is ROM volatile or non-volatile?
16. What does ROM stand for?
- Random Only Memory
- Random Offset memory
- Read Only Memory
- Read Often Memory
