Non-volatile memory technologies, like flash memory and hard drives, allow a computer to retain information without power. These storage media use special electronic mechanisms to save data that persists even when the device is turned off. So, even after a power loss, the information stored remains intact and accessible when the computer is powered back on.

FAQs & Answers

  1. What is the difference between volatile and non-volatile memory? Volatile memory requires power to maintain stored information, while non-volatile memory retains data even when power is off.
  2. How does flash memory work? Flash memory stores data using electrical charges in cells that can hold their state even without power, allowing for data retention.
  3. What are the uses of non-volatile memory? Non-volatile memory is used in computers, smartphones, and other electronic devices to store the operating system, applications, and user data.
  4. Can data stored in hard drives be corrupted? Yes, data on hard drives can become corrupted due to factors like physical damage, power failure, or software issues.
