What is one key characteristic that distinguishes non-volatile memory from volatile memory?

One key characteristic that distinguishes non-volatile memory from volatile memory is data retention capabilities. Non-volatile memory retains its data even when power is removed, meaning that the information stored within remains intact and accessible for use when the device is powered down. This is in contrast to volatile memory, which loses its stored data when power is lost, necessitating a continuous power supply to maintain information.

This data retention feature makes non-volatile memory essential for storing important information on devices such as hard drives, flash drives, and solid-state drives. In scenarios where preserving data is critical, non-volatile memory is favored due to its reliability in maintaining data integrity without the need for constant power.
