A thumb drive, or USB flash drive, is a small device which can be inserted into a USB port in a computer or other electronic device in order to provide storage or transfer of data. It resembles a disk drive to the computer, but has no moving parts; flash memory is used. They are widely used due to their compact size (smaller than a floppy disk or CD) and high storage capacity (as much as a terabyte now). The memory is nonvolatile, so it will hold its data indefinitely just like a disk, and is freely readable and writable like a floppy or hard disk.
Many varieties of thumb drives exist with different data capacities.
Because the thumb drive is an electronic device with some in-built intelligence of its own which responds to read and write requests, it is possible to create "hacked" drives which do unusual things such as wipe themselves out if unwanted data retrieval events take place. Such techniques are discussed in a video lecture linked below.
