random-access

The term "random-access" is a modern technical compound, primarily coined in the mid-20th century to describe a revolutionary type of computer memory. The first element, "random," draws from its established meaning of lacking a definite aim or pattern, which in this context signifies the ability to reach any data point directly, without proceeding in a predetermined sequence. The second element, "access," from the Latin concept of approaching or entering, is used in computing to denote the retrieval or storage of information. Thus, the compound's literal logic—"approaching (data) in a non-sequential manner"—perfectly captures the technical capability where any storage location can be read or written with equal speed, in contrast to sequential-access methods like magnetic tape.

Structure: random (by chance) + access (approach/entry) - random: From Old French randon 'impetuosity, speed', of Germanic origin. In this compound, it conveys the sense of 'without a fixed pattern or sequence'. - access: From Latin accessus 'approach, entry', from accedere 'to approach'. In this compound, it refers to the ability to retrieve or store data.
