What is the most important difference between primary memory and secondary storage?

Answer and explanation

Correct answer: Primary memory is used directly in active processing while secondary storage keeps long-term data

The governing concept is the different role of working memory and long-term storage. Primary memory, especially RAM, gives the CPU relatively fast access to instructions and data needed by currently running tasks. Secondary storage, such as an SSD or hard drive, preserves files and programs for longer-term use, usually without continuous power. Therefore option D is correct; the other options confuse storage roles with output or calculation.
