What describes data stored in volatile memory?

Data stored in volatile memory is characterized by its dependence on a continuous power supply. When power is lost, any information stored in this type of memory is immediately lost as well. This is a fundamental property of volatile memory, which includes types such as RAM (Random Access Memory). Unlike non-volatile memory, which retains data even when powered off (like hard drives or flash storage), volatile memory's primary function is to provide quick read and write access to data while the system is operational. Therefore, the correct answer highlights the critical nature of power in relation to the retention of data in volatile memory.
