USB (“universal serial bus”) flash drive is a small‚ portable‚ external flash drive that plugs into a computer’s USB port. Like hard disks‚ USB flash drives store information‚ but they more easily transfer that information from one device to another. A USB flash drive has three basic components – the board‚ the NAND flash memory storage chip‚ and the controller chip. The board holds all of the internal components and includes the USB connector. The flash drive uses the board as a means of transferring
