13.4 Flash memory

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. These cards are used in portable devices such as digital cameras and in small portable computers, such as Personal Digital Assistants (PDAs).

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.
