Answer : 2. "RAM "
Explanation :
RAM (Random Access Memory) is an example of volatile memory. Volatile memory is a type of computer memory that requires power to maintain the stored information. When the computer is powered off or restarted, the data stored in RAM is erased. This is in contrast to non-volatile memory like hard drives or SSDs, where data is retained even when the power is turned off. Volatile memory, such as RAM, provides fast access to data for the computer's processor but does not retain data when the system is powered down.
