Read-only memory stands for?

• A. Random Access Memory
• B. Read-Only Memory
• C. Electrically Alterable PROM
• D. Magnetic storage unit

Answer: (B)

ROM stands for Read-Only Memory. It’s non-volatile storage, meaning it retains its data without power, and it’s intended to be read rather than regularly written to by programs. This makes ROM ideal for storing firmware or boot instructions that must be available when the system starts. In contrast, Random Access Memory is volatile and loses its contents when power is off, which is suitable for data the CPU needs immediately but not for long-term storage. The other options point to different concepts: magnetic storage refers to drives, and Electrically Alterable PROM is a type of programmable ROM, but the standard meaning of ROM is Read-Only Memory.
