A USB flash drive, also variously known as a USB drive, USB stick, thumb drive, pen drive, jump drive, flash-drive or USB memory, is a data storage device that includes flash memory with an integrated USB interface. USB flash drives are typically removable and rewritable, and physically much smaller than an optical disc.
Use of USB On-The-Go allows those devices to switch back and forth between the roles of host and client devices. For instance, a mobile phone may read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer.n other words, USB On-The-Go introduces the concept of a device performing both master and slave roles â whenever two USB devices are connected and one of them is a USB On-The-Go device, they establish a communication link.
