Browse Definitions by Alphabet
- logical partition (LPAR) - A logical partition (LPAR) is a subset of a computer's processor, memory and I/O resources that behaves much like a physical server.
- logical unit number (LUN) - A logical unit number (LUN) is a unique identifier for designating an individual or collection of physical or virtual storage devices that execute input/output (I/O) commands with a host computer, as defined by the Small System Computer Interface (SCSI) standard.
- logical volume management (LVM) - Logical volume management (LVM) is a form of storage virtualization that offers system administrators a more flexible approach to managing disk storage space than traditional partitioning.
- logistic regression - Logistic regression is a statistical analysis method to predict a binary outcome, such as yes or no, based on prior observations of a data set.
- logistics - Logistics is the process of planning and executing the efficient transportation and storage of goods from the point of origin to the point of consumption.
- logistics management - Logistics management is the governance of supply chain management functions that helps organizations plan, manage and implement processes to move and store goods.
- logon (or login) - In computing, a logon is a procedure that enables an entity to access a secure system such as an operating system, application, service, website or other resource.
- longitudinal time code (LTC) - Longitidinal time code (LTC) is a timing signal that is part of an audio tape recording.
- loop - In computer programming, a loop is a sequence of instructions that is continually repeated until a certain condition is reached.
- loose coupling - Loose coupling is an approach to interconnecting the components in a system, network or software application so that those components, also called elements, depend on each other to the least extent practicable.
- lossless and lossy compression - Lossless and lossy file compression describe whether all original data can be recovered when the file is uncompressed.
- low earth orbit (LEO) satellite - A low earth orbit (LEO) satellite is an object, generally an electronic piece of equipment, that circles around the earth at lower altitudes than geosynchronous satellites.
- low-code and no-code development platforms - Low-code/no-code development platforms are software development tools and environments that allow enterprise developers and citizen developers to create new applications using drag-and-drop components, linking them together and creating mobile or web apps.
- lowerCamelCase - A part of CamelCase, lowerCamelCase is a naming convention in which a name contains multiple words that are joined together as a single word.
- loyalty card program - A loyalty card program is an incentive plan that allows a retail business to gather data about its customers.
- LPT (line print terminal) - LPT (line print terminal) is the usual designation for a parallel port connection to a printer or other device on a personal computer.
- LPWAN (low-power wide area network) - Low-power WAN (LPWAN) is a wireless wide area network technology that interconnects low-bandwidth, battery-powered devices with low bit rates over long ranges.
- LTE (Long-Term Evolution) - LTE (Long-Term Evolution) is a fourth-generation (4G) wireless standard that provides increased network capacity and speed for cellphones and other cellular devices compared with third-generation (3G) technology.
- LTE-Advanced (Long Term Evolution-Advanced) - Long Term Evolution-Advanced (LTE-Advanced) is a cellular networking standard that offers higher throughput than its predecessor, the Long Term Evolution (LTE) standard.
- LTFS (Linear Tape File System) - LTFS (Linear Tape File System) is a file system specification that allows Linear Tape-Open (LTO) storage technology to be indexed.
- LTO (Linear Tape-Open) tape - LTO (Linear Tape-Open) tape is an open-format tape storage technology created by Hewlett-Packard (HP), International Business Machines (IBM) and Seagate Technology.

- LTO-9 (Linear Tape-Open 9) - LTO-9 (Linear Tape-Open 9) is a future tape format from the Linear Tape-Open Consortium.
- Luddite - A Luddite is a person resistant to increased industrialization or new technologies, especially computers.
- Luhn algorithm (modulus 10) - The Luhn algorithm, also called modulus 10 or modulus 10 algorithm, is a simple mathematical formula used to validate a user's identification numbers.
- LUN masking - LUN masking is an authorization mechanism used in storage area networks (SANs) to make LUNs available to some hosts but unavailable to other hosts.
- lux (lx) - The lux (symbolized lx) is the unit of illuminance in the International System of Units (SI).
- LXD (Linux container hypervisor) - LXD is an open source container management extension for Linux Containers (LXC).
- LZW compression - LZW compression is a method to reduce the size of Tag Image File Format (TIFF) or Graphics Interchange Format (GIF) files.
