Why is RAM considered volatile?

• A. It cannot be upgraded
• B. It requires constant power to keep stored data
• C. It is only used for temporary storage
• D. It is slow compared to ROM

Answer: (B)

RAM, or Random Access Memory, is classified as volatile because it requires a continuous supply of power to maintain the data stored within it. When the computer is turned off or loses power, the information held in RAM is lost. This characteristic is fundamental to its operation, as it allows for rapid reading and writing of data, which is essential for the functionality of running applications and processes efficiently.

The need for constant power is what distinguishes volatile memory, like RAM, from non-volatile memory types, such as hard drives or SSDs, which retain data even when the device is powered down. Understanding this nature of RAM highlights its role in computing: serving as a temporary workspace for the processor to access data quickly while performing tasks.
