What does the acronym DRAM stand for?

The acronym DRAM stands for Dynamic Random Access Memory. This type of memory is essential in computer systems as it allows for the temporary storage of data that the CPU needs while performing tasks. The term "dynamic" refers to the need for the memory cells in DRAM to be refreshed periodically to maintain the stored information. This differentiates it from static RAM, which does not require constant refreshing.

In contrast, the other terms presented do not accurately define DRAM or correspond to any standardized memory types. For instance, "Digital refresh access memory" does not exist as a recognized term in computing, and neither do "Digital recording access memory" nor "Digital response area motion." These options may sound plausible, but they do not relate to standard definitions used in the context of computer memory technologies.
