Which among the following is a Flash memory device?

A USB drive (also known as a thumb drive or flash drive) uses Flash memory, which is a type of non-volatile storage. This means it keeps your data even when the power is turned off, unlike RAM. It works by using electronic circuits to trap electrons, allowing for fast reading and writing without any moving parts.Why the others are different:Hard Disk Drive (HDD): This is a magnetic storage device. It uses spinning platters and a moving read/write head (similar to a record player) to store data.Random Access Memory (RAM): This is volatile memory. It is very fast, but it loses all stored data the moment the computer is powered down.Blu-Ray disc: This is an optical storage device. It uses a blue laser to read and write data from microscopic pits on the surface of the disc.
