In recent years flash memory storage devices have grown in popularity as a removable storage medium. Typical memory sticks have large capacity and can be purchased with storage between 1 GB and 32 GB.
The memory stick shown on the right has many features; it is small, lightweight, removable, and can be rewritten. Internally it consists of a small printed circuit board which is encased in plastic or metal casing and is usually fitted with a removable cap which covers and protects the part of the stick which is inserted into a USB port.
Flash memory cards, shown on the left, are built using similar technology to memory sticks, and are used as a storage medium in a range of computing devices such as digital cameras and personal digital assistants (PDAs).
