Technology used in devices, such as optical drives, which detects changes in light caused by irregularities on a surface

external hard drive

A disk drive connecting to a computer via a cable in which you can store data and retrieve it from another computer.

flash drive

Small, convenient device to store data and take it with you. Also known as a USB stick or thumb drive.

flash memory

A type of computer memory used to record and erase stored data and also to transfer data to and from a computer. It is used in mobile phones and digital cameras because it is less expensive than other types of memory.

input device
