L - Definitions

  • L

    lambda switching (photonic switching, or wavelength switching)

    Lambda switching (sometimes called photonic switching, or wavelength switching) is the technology used in optical networking to switch individual wavelengths of light onto separate paths for specific routing of information.

  • LAN party

    A LAN party is a gathering in which gamers (devotees of computer games) gather to share a local area network (LAN) and participate in extended gaming sessions of popular games such as Quake, Doom, or Wolfenstein.

  • LAN server

    A local area network (LAN) server is a program (and by implication usually the computer it runs in) that "serves" the resources (files, storage, application programs, printers, and other devices) for a number of attached workstations.

  • LANDesk Client Manager (LDCM)

    LDCM (LANDesk Client Manager) is a software product from Intel that lets a system administrator for a local area network () see the configurations and monitor the status of personal computer on the LAN. LDCM is an implementation of the Desktop Management Interface (DMI) standard established by the Desktop Management Task Force, an industry group.

  • last-mile technology

    Last-mile technology is any telecommunications technology that carries signals from the broad telecommunication backbone along the relatively short distance (hence, the "last mile") to and from the home or business.

  • layer 2

    Layer 2 refers to the Data Link layer of the commonly-referenced multilayered communication model, Open Systems Interconnection (OSI).

  • LEC (local exchange carrier)

    LEC (local exchange carrier) is the term for a public telephone company in the U.S. that provides local service.

  • line doubler

    A line doubler is an electronic device that converts analog or digital television (TV) video signals into a format suitable for display on a computer monitor.

  • line information database (LIDB)

    A line information database (LIDB) is a database maintained by the local telephone company that contains subscriber information, such as a service profile, name and address, and credit card validation information.

  • Link Control Protocol (LCP)

    In the Point-to-Point Protocol (PPP), the Link ControlProtocol (LCP) establishes, configures, and tests data-link Internet connections.

  • Link Quality Source Routing (LQSR)

    LQSR (Link Quality Source Routing) is a routing protocol for wireless mesh networks. The protocol was developed by Microsoft for use with their MCL (Mesh Connectivity Layer) technology, which facilitates the interconnection of computers into a mesh network using WiFi or WiMax wireless services. The LQSR protocol is based on DSR (Dynamic Source Routing).

  • link-load balancer (link balancer)

    A link load balancer, also called a link balancer, is a network appliance that distributes in-bound and out-bound traffic to and from multiple Internet Service Providers (ISPs) links.
