Which term is defined as random access memory?

• A. Random Access Memory
• B. Solid State Drive
• C. ROM
• D. Cache

Answer: (A)

Random Access Memory is the computer’s primary memory that holds data the CPU is actively using. It’s called random access because you can read or write to any location in memory in roughly the same amount of time, unlike storage devices that require sequential access. RAM is volatile, so its contents disappear when power is turned off, which is why you save work to non-volatile storage.

The other terms refer to different kinds of memory or storage. A solid-state drive is long-term, non-volatile storage for keeping data permanently. ROM stands for Read-Only Memory and typically holds firmware that isn’t meant to be changed during normal operation. Cache is a very small, ultra-fast memory near the CPU used to speed up access to frequently used data, not the main memory used for active work. So the correct term for random access memory is RAM itself.
