Contents stored in Read-Only Memory (ROM) or Non-Volatile Storage like hard drives, SSDs, and external storage devices are not lost when the computer is turned off. These storage mediums retain data even without power, unlike RAM, which loses data when powered down. To keep your important files safe, always save them to these permanent storage options.

FAQs & Answers

  1. What is Read-Only Memory (ROM)? Read-Only Memory (ROM) is a type of non-volatile storage that retains data even when the power is off, used primarily for firmware.
  2. How does RAM differ from hard drives? RAM (Random Access Memory) is volatile and loses all stored data when powered off, while hard drives and SSDs retain data without power.
  3. What types of storage are considered non-volatile? Non-volatile storage includes hard drives, solid-state drives (SSDs), and external storage devices that keep data even when the device is turned off.
  4. What is the importance of using non-volatile storage? Using non-volatile storage is essential for ensuring data safety and accessibility, even when the computer is not powered on.
