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
- 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 representing the binary
8. How could increasing RAM increase what the OS can store?
- It can store more programs, bigger programs, more files and bigger files
- It can store more data, bigger data, more files and bigger files
- It can store more programs, bigger programs, more data and bigger data
9. What is stored in RAM when a computer system is in use?
- The OS (and any files it is using), any programs that are loaded by the user and any data loaded by the user
- The BIOS and any other permanent programs or data
- Documents, files, webpages or any other data that are loaded by the user
- Any software the computer is using
10. Explain why programs do not run directly from secondary storage
- It is too small to store all the programs the CPU needs to run
- It is too slow for programs to run directly by the CPU
- It is too expensive
- Secondary storage can be removed from the computer
11. Disadvantage of storing a program in ROM
- It is non-volatile so contents are not lost when the power turns off
- The program can be updated and any data stored on the chip can be changed
- The program cannot be updated and any data stored on the chip cannot be changed
- It is volatile so contents are not lost when the power turns off
12. What is stored in RAM?
- Programs and files
- Documents and files
- Programs and data that are currently in use by the CPU
- Fixed programs and data that are currently in use by the CPU
13. Is RAM volatile or non-volatile?
14. What does ROM stand for?
- Random Offset memory
- Read Often Memory
- Read Only Memory
- Random Only Memory
15. 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
16. Explain the purpose of RAM in a computer system
- Process instructions from the CPU
- Execute instructions
- Store data and programs that the CPU is using while programs are running
- Temporarily store instructions and data being used by the CPU
17. What are the functions of the BIOS program?
- Allow the CPU to access hardware, check hardware, allow the user to change some basic settings, and load OS into ROM
- Check hardware, allow the user to view and edit basic settings, and load OS into RAM
- Allow the CPU to access hardware, check hardware, allow the user to view and edit basic settings, and load OS into RAM
- Allow the CPU to access hardware, allow the user to view and edit basic settings, and load OS into RAM
18. Advantage of storing a program in ROM
- It is non-volatile so contents are not lost when the power turns off
- It is volatile so contents are not lost when the power turns off
- The program cannot be updated and any data stored on the chip cannot be changed
- The program can be updated and any data stored on the chip can be changed
19. What does RAM stand for?
- Read Alternative Memory
- Read Access Memory
- Random Access Memory
- Random Alternative Memory
20. What does volatile mean?
- Contents will be lost when the power turns off
- Contents will not be lost when the power turns off
