I keep getting this wrong, please help

Select all of the following statements that are true. If you don't recall the answers from the lecture, you are welcome to search the course Module slides or use your favorite Internet search engine. some memory is volatile meaning that the values of bits are lost when the power is off. Read Only Memory (ROM) cannot be used to store programs because programs need to be modified (re-written) as they run. ROM is only used to store data Some memory is non-volatile meaning that it preserves the values of bits even when power is off Volatile memory is always faster than non-volatile memory. Faster means the values stored in memory can be read or written more times per second than slower memory. Random Access Memory (RAM) is volatile memory that can be read or written at any address. Paper tape cannot be used as memory. Registers are typically the fastest memory in a computer. Machine instructions usually read and write bits from registers. Registers are not memory

Explanation / Answer

1-Some memory are volatile meaning that the values of bits are lost when the power is off- True the data in volatile memory remains in memory untill the power is ON.
3-Some memory is non-volatile meaning that it preserves the values of bits even when power is OFF-True.
4-Volatile memory is always faster than non volatile memory-True as RAM is volatile memory and it is always faster to write or read from RAM than any other storages.

5-RAM is volatile memory which can be read or written at any address- true

7-Registers are typically fastest in a computer . Machine instructions usually read and write bits from registers-True all the data storage transfers are done through registers.
9-Operating system is program or collection of programs. - True as an operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs.
10-A computer program is a collection of instructions for a computer to perform a specific sequence of operations-True
12-A process is a program that is least partially stored in memory. A process is usually eirher currently executing or ready to execute if whatever resources the program is waiting for become available. Some processes can be in a zombie state which means the program is dead and will never be resumed but its process data structure hasn't been de allocated by the operating system.-True
