Which of the following is considered volatile memory?

Volatile memory refers to a type of computer memory that requires power to maintain the stored information. Once the power is turned off, any data stored in volatile memory is lost, making it essential for short-term data storage and processing needs.

Random Access Memory (RAM) is classified as volatile memory because it is used by the processor to store data and applications currently in use. When you turn off your computer, any data that resides in RAM is wiped out. This characteristic of needing a constant power supply distinguishes it from non-volatile memory types, like hard drives and flash drives, which retain data even when the device is powered down.

In contrast, hard drives, optical drives, and flash drives are all types of non-volatile memory. They maintain stored information without a continuous power supply. This distinction is crucial for understanding how different types of memory function in computing environments.
