Which feature distinguishes ROM from RAM?
ROM stores permanent instructions; RAM stores temporary data.
ROM (Read-Only Memory) is non-volatile: it retains its contents even when the power is switched off, so it holds permanent instructions like the firmware/BIOS that boots the computer.
RAM (Random Access Memory) is volatile: it loses its contents when power is removed, so it holds temporary working data and the programs currently in use.
The other statements are wrong: RAM is actually faster than ROM, ROM is not a graphics store, and the volatility is the reverse of what the last option claims (RAM is volatile, ROM is non-volatile).
Hence, the distinguishing feature is that ROM stores permanent instructions while RAM stores temporary data.
