Detailed explanation-4: -Flash storage uses a type of nonvolatile memory called flash memory. Nonvolatile memory doesn’t require power to maintain the integrity of stored data, so even if your power goes out, you don’t lose your data. In other words, nonvolatile memory won’t “forget” the data it has stored when the disk is turned off.

Detailed explanation-5: -A USB flash drive–also known as a USB stick, USB thumb drive or pen drive–is a plug-and-play portable storage device that uses flash memory and is lightweight enough to attach to a keychain.
