Which type of memory is volatile and loses data when power is turned off?

Which type of memory is volatile and loses data when power is turned off?

• A. Cache
• B. RAM
• C. ROM
• D. Storage device

Answer: (B)

Volatile memory loses its contents when power is removed. RAM is the computer’s working memory, holding the active programs and data while the system runs. Because it relies on electricity, anything stored in RAM vanishes as soon as power is cut. ROM, storage devices, and even cache memory behave differently: ROM and storage keep data without power (non-volatile), while cache is a fast, small part of RAM used to speed up access, but it’s still volatile. So RAM best fits the description of memory that loses data when power is turned off.
