Basic Computer/IT QUESTION #11440
Question 1
Which key feature makes Read-Only Memory (ROM) essential in computing?
  • ROM information can be easily updated
  • Data in ROM is non-volatile, meaning it retains information without power✔️
  • ROM offers large quantities of cheap storage
  • ROM chips are easily hot-swapped between computer brands

ROM (Read-Only Memory) is non-volatile — its contents are retained even without power. This makes it ideal for storing firmware (BIOS/UEFI) and boot instructions. ROM is pre-programmed during manufacture and cannot be modified under normal operating conditions.
