DVD-RAM:A Digital Versatile Disc-Random Access Memory is a high- capacity, high performance disc that lets you store large volumes of data. The DVD-ROM drive uses a laser to read data from the disc.

DVD-ROM:A Digital Versatile Disc-Read Only Memory is a high capacity, high performance disc suitable for play back of video and other high- density files. The DVD-ROM drive uses a laser to read data from the disc.

DVD-RW (+RW, -RW):A Digital Versatile Disc-ReWritable disc can be rewritten many times.

E

echo: To send back a reflection of the transmitted data to the sending device. You can display the information on the screen, or output it to the printer, or both.

F

fast infrared: An industry standard that enables cableless infrared serial data transfer at speeds of up to 4 Mbps.

file: A collection of related information; a file can contain data, programs, or both.

fingerprint sensor: The fingerprint sensor compares and analyzes the unique characteristics in a fingerprint.

firmware: A set of instructions built into the hardware which controls and directs a microprocessor’s activities.

flash memory: Non-volatile memory that can be written to as well as read. Information in flash memory remains whether or not the computer is receiving power. This type of memory is used to retain your fingerprint data. See also memory. Compare RAM and ROM.
