low-bandwidth
[communication theory] Used to indicate a talk that, although not content-free, was not terribly informative. "That was a low-bandwidth talk, but what can you expect for an audience of suits!" Compare zero-content, bandwidth, math-out. [Jargon File]Low Bandwidth X
(LBX) An implementation of the X Window System designed to improve performance over ISDN, WAN, and serial lines.

low earth orbit
(LEO) The kind of orbit used by communications satellites that will offer high bandwidth for video on demand, television, and Internet communications. A satellite in LEO, in contrast to one in a geostationary orbit, is not in a fixed position relative to the Earth's surface so several satellites are required to provide continuous service.

Lower Layer Protocol
(LLP, or lower-layer protocol) Any protocol residing in OSI layers one to four.
These protocols package, route, verify and transmit datagrams. A prime example would be TCP/IP. Lower layer protocols support the upper layer protocols.Last updated: 1999-02-17

Low Insertion Force
<hardware>
(LIF) PGA/SPGA sockets with no handle. The integrated circuit is simply pushed into the socket, and levered out to remove. Most motherboard processor sockets are now ZIF rather than LIF.

low-level language
<language>
Any programming language which either is assembly language, or which is meant to be closely related to, and easily translated into, machine language. Low-level languages lack the amenities of high-level languages but it may be possible to write more efficient code in them.

In image processing, a low pass filter might be used to remove noise from an image.Last updated: 2000-04-19
Low Voltage Differential
<hardware>
(LVD) A method of driving SCSI cables that will be formalised in the SCSI-3 specifications. LVD uses less power than the current differential drive (HVD), is less expensive and will allow the higher speeds of Ultra-2 SCSI. LVD requires 3.3 Volts DC instead of 5 Volts DC for HVD.
