Volatile memory elements can be classified as those that
A) do not retain stored information when the power is removed.
B) retain stored information when the power is removed.
C) do not require a battery backup.
D) both retain stored information when the power is removed and do not require a battery backup.
Volatile Memory Elements
Components of memory that require power to maintain stored information, such as RAM in computers.
Battery Backup
An alternate power source intended to provide electricity to essential devices in the event of a primary power failure.

Final Answer :
A
Explanation :
Volatile memory elements do not retain stored information when the power is removed. Non-volatile memory elements, on the other hand, retain stored information even when power is removed. Option B is incorrect because it describes non-volatile memory elements, not volatile memory elements. Option C is not relevant to the classification of memory elements as volatile or non-volatile. Option D is incorrect because it includes characteristics of both volatile and non-volatile memory elements.
