Question

What is the difference between a computer’s RAM and its hard disk?

A. RAM is not volatile, which means that it is more reliable than a hard disk. A hard disk is volatile, which means that it is vulnerable to electronic interference.

B. RAM is volatile, which means that it does not retain information in memory after powering down. A hard is not volatile, which means that it retains information in memory after powering down.

C. RAM is not volatile, which means that it retains information in memory after powering down. A hard disk is also not volatile, which means that it retains information in memory after powering down.

D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.

Answer 1

Step-by-step explanation:

RAM can be accessed faster than hard drive. – Any changes made to the file will be present in RAM while once the changes are saved it is copied to the hard drive permanently. – RAM needs power to store data, hard drives do not.

Answer 2

D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.

Step-by-step explanation:

Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.
