What describes the primary use of DRAM?

Dynamic Random Access Memory (DRAM) is primarily utilized for temporary storage of data in computing systems. It is characterized by its need for periodic refreshing to maintain the stored information. This is due to the nature of the memory cells in DRAM, which store data as electrical charges in capacitors. These charges tend to leak away over time, making refresh cycles necessary to ensure that the data remains intact.

The temporary aspect of DRAM makes it well-suited for tasks that require both speed and volatility, such as serving as the main memory in computers and other devices where quick access to data is essential but where the data does not need to be retained once the power is off. This contrasts with permanent storage solutions, such as hard drives or SSDs, and is why the option highlighting temporary storage requiring refresh is the correct choice.
