FDE hard drive
Short for full-disk encryption (FDE) hard drive it is a Seagate technology that performs encryption on the disk drive at the hardware level. The hard drive contains an ASIC chip that is used to encrypt every bit of data as it is written and also decrypts data as it is being read. The drive requires a user password for authentication and it is secured with strong encryption technology. Seagate’s FDE technology is transparent to the user and independent of the operating system. Also called a self-encrypting drive.

- FDHD
Short for floppy drive, high density, and pronounced fud-hud. FDHD refers to 3½-inch disk drives for Macintosh computers that can accept double-density or high-density 3½-inch floppy disks. FDHDs can also read DOS -formatted floppy disks, which enables Macintosh computers and PCs to share data. FDHD drives are often called SuperDrives.
- FDM
Short for frequency division multiplexing, a multiplexing technique that uses different frequencies to combine multiple streams of data for transmission over a communications medium. FDM assigns a discrete carrier frequency to each data stream and then combines many modulated carrier frequencies for transmission. For example, television transmitters use FDM to broadcast several channels at once.
- FEC
Short for forward error correction, a method of communicating data that corrects errors in transmission on the receiving end. Prior to transmission, the data is put through a predetermined algorithm that adds extra bits specifically for error correction to any character or code block. If the transmission is received in error, the correction bits are […]
- FECN
Short for forward explicit congestion notification. A Frame Relay message that notifies the receiving device that there is congestion in the network. A FECN bit is sent in the same direction in which the frame was traveling, toward its destination. Compare with BECN.
- FED
Short for Field Emission Display, it is a flat-panel display where a grid of electron emitters are controlled by cold cathodes to generate color light. FEP technology combines flat panel technology with the high quality of a CRT display but requires less power than a CRT. This technology was first announced by Candescent Technologies under […]
