Morphology

random + access + memory

The phrase is compositionally analyzable—B1 learners who know 'random', 'access', and 'memory' can infer it refers to memory that can be accessed in a non-sequential or arbitrary order. However, the full technical sense (volatile, program working storage and the specialized computing sense of 'random access' versus ordinary 'random') requires domain knowledge, so the meaning is not fully predictable from the parts for an average B1 learner.

Etymology

Random access memory comes from the idea that the computer can reach any part of its memory directly. Imagine a library where you can pull any book from any shelf without reading the others—random means not in order and access means 'get to', so the name explains why this memory lets a computer quickly store and read data while it runs.
