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.
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 […]
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.
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 […]
Short for Foldable Electronic Memory Module Assembly, it is the trademarked product name of Kentron Technologies’ low profile memory modules. FEMMA is utilized in the 1U and blade server platforms, and other markets where space and height constraints are at a minimum.
Short for front end processor, the FEP is a computer that handles input and output communications for large mainframe computer which reduces the load on the computer. A FEP is also called a communications controller.
