Dollar amounts of added value due to labor performed during manufacturing. [APIC]. Cost and labor reporting on construction activities.
Labor Grade
A classification of labor into separate groupings of those whose capability makes them unique in terms of their particular skill level or craft. [APIC].
LAN
Local Area Network. Local area networks are a communications mechanism by which computers and peripherals in a limited geographical area can be connected. They provide a physical channel of moderate to high data rate (typically 1 to 100 Mbit/sec) which has a consistently low error rate (typically 10-9).
Layer
A subdivision of the OSI architecture (See OSI Reference Model).
Lead Time
A span of time required to perform an activity. In a logistics context, it is the time between recognition of the need for an order and the receipt of goods. Individual components of lead time can include order preparation time, queue time, move or transportation time, and receiving and inspection time. [APIC].
Line Driver
A circuit specifically designed to transmit digital information over long lines, that is, extended distances.
LISP
A programming language (LIST Processing) designed specifically to manipulate symbols rather than numeric data. A LISP data element is a list of symbols that may represent any object, including its own list processing functions. [DEC].
LISP Interpreter
A part of any LISP-based software tools that allows specific list-processing operations such as match, join, and substitute, to execute on a general purpose computer rather than a special purpose LISP machine. [DEC].
LISP Machine
A single-user workstation with a dedicated LISP programming architecture. [DEC].
List
In a list processing software language, a list is an ordered sequence of elements. [DEC].
LLC
Logical Link Control. The upper sub-layer of the data link layer (Layer 2) used by all types of IEEE 802 LANs. LLC provides a common set of services and interfaces to higher layer protocols. Three types of services are specified:
Type 1: Connectionless. A set of services that permit peer entities to transmit data to each other without the establishment of connections.
Type 2: Connection oriented. A set of services that permit peer entities to establish, use, and terminate connections with each other in order to transmit data.
Type 3: Acknowledged connectionless. A set of services that permit a peer entity to send messages requiring immediate response to another peer entity. This class of services can also be used for polled (master-slave) operation.
Logical Cells
Consists of a set of Specified Components and support a set of Enterprise Activities. [CIM-OSA].
Logistics Documents
Documents to support field operations, such as instruction manuals, training information, spares, modification and maintenance information. [SAMA].
Lot
A quantity of items produced together and sharing the same production costs and resultant specifications. [APIC].
Lot ID
A unique identification number or code assigned to a homogeneous quantity of material (e.g., a batch number or mix number). [APIC].
Lot Traceability
The ability to identify the lot or batch numbers of consumption and/or composition for manufactured, purchased and shipped items. This is a federal requirement in certain regulated industries. [APIC].
