What is a flash drive?
A flash drive is a small, portable data storage device that plugs into the USB port of a computer (or another USB-equipped device, such as an MP3 player). Depending on your operating system, you can typically move data to and from the flash drive just as you would any other storage medium (e.g., a hard drive or floppy disk). Flash drives are popular because they can hold a considerable amount of data and are fast, reliable, and portable.
