LPAR
Short for logical partitioning, a system of taking a computer’s total resources – processors, memory and storage — and splitting them into smaller units that each can be run with its own instance of the operating system and applications. Logical partitioning, which requires specialized hardware circuits, is typically used to separate different functions of a system, such as Web serving, database functions, client/server actions or systems that serve multiple time zones and/or languages. Logical partitioning can also be used to keep testing environments separated from the production environments. Since the partitions in effect act as separate physical machines, they can communicate with each other. IBM was the first to use logical partitioning in 1976.

- LPD/LPR
Short for line printer daemon/line printer remote, a printer protocol that uses TCP/IP to establish connections between printers and workstations on a network. The technology was developed originally for BSD UNIX and has since become the de facto cross-platformprinting protocol. The LPD software typically is stored in the printer or print server and the LPR […]
- LPT
A name frequently used by operating systems to identify a printer. Although LPT originally stood for line printer terminal, it is now used more generally to identify any type of printer.
- LPX
A motherboard form factor used in some desktop model PCs. The distinguishing characteristic of LPX is that expansion boards are inserted into a riser that contains several slots. So the expansion boards are parallel to the motherboard rather than perpendicular to it as in other common form factors, such as AT and ATX. The LPX […]
- LRC
Short for longitudinal redundancy check, it is an error detection and checking method used to verify the accuracy of stored or transmitted data. LRC works by generating a parity bit from a specified string of bits on a longitudinal track.
- LSI
(1) Short for large-scale integration. (2) Short for Latent semantic indexing.
