Memory in which each cell can be directly accessed and its contents can be changed.

Memory in which each cell can be directly accessed and its contents can be changed.

• A. ROM
• B. RAM
• C. Cache
• D. Registers

Answer: (B)

Random Access Memory (RAM) is memory where each cell can be directly accessed and its contents changed. This direct addressability, or “random access,” means you can read from or write to any location in memory quickly, without going through a fixed sequence. RAM is writable and volatile, so it holds data while programs run but loses it when power is off. ROM, on the other hand, is non-volatile and typically read-only, so its contents aren’t changed during normal operation. Cache is a small, very fast type of RAM used to speed up access to frequently used data, but the core idea of being directly writable and addressable points to RAM. Registers are tiny storage inside the CPU that are also writable, but the description matches the main writable memory used for active data and programs, i.e., RAM.
