Flash memory is an electronic form of memory which can be used, erased and reused. A flash memory card is a small storage device used to store data such as text, pictures, sound and video.

A USB flash memory, sometimes called a 'memory stick', is a small storage device which is completely external and connects to the computer via a USB port. This portable memory comes in different capacities, e.g. 256 MB, 512 MB, 1 GB and 2 GB.
