(2) The combination of physical media, protocols, and
programming that connects devices on a network.
(3) In computer programming, the part of a program, in
some cases a single instruction or an address, that
passes control and parameters between separate
portions of the computer program. (4) To interconnect
items of data or portions of one or more computer
programs. (5) In SNA, the combination of the link
connection and link stations joining network nodes.
LLC. Logical link control.
local area network (LAN). A computer network
located on a user’s premises within a limited
geographical area.
Note: Communication within a local area network is not
subject to external regulations; however, communication
across the LAN boundary may be subject to some form
of regulation.
locally administered address. An adapter address
that the user can assign to override the universally
administered address. Contrast with
universally
administered address.
LSB. Least significant bit.
LSL. Link support layer.
M
Mbps. Megabits per second.
MBps. Megabytes per second.
medium. A physical carrier of electrical or optical
energy.
media access control (MAC) protocol. In a local
area network, the part of the protocol that governs
communication on the transmission medium without
concern for the physical characteristics of the medium,
but taking into account the topological aspects of the
network, in order to enable the exchange of data
between data stations.
MHz. Megahertz.
MPTS. Multiple Protocol Transport Services.
MSB. Most significant bit.
N
NDIS. Network driver interface specification.
NetBIOS. Network Basic Input/Output System. An
operating system interface for application programs
used on IBM personal computers that are attached to
the IBM Token-Ring Network. See also
BIOS.
NLM. NetWare loadable module.
network administrator. A person who manages the
use and maintenance of a network.
network architecture. The logical structure and
operating principles of a computer network. See also
systems network architecture (SNA) and Open Systems
Interconnection (OSI) architecture.
Note: The operating principles of a network include
those of services, functions, and protocols.
node. (1) Any device, attached to a network, that
transmits and/or receives data. (2) An endpoint of a
link, or a junction common to two or more links in a
network. (3) In a network, a point where one or more
functional units interconnect transmission lines.
node address. The address of an adapter on a LAN.
O
OEM. Original equipment manufacturer.
open. (1) To make an adapter ready for use. (2) A
break in an electrical circuit. (3) To make a file ready
for use.
Open Systems Interconnection (OSI). (1) The
interconnection of open systems in accordance with
specific ISO standards. (2) The use of standardized
procedures to enable the interconnection of data
processing systems.
Note: OSI architecture establishes a framework for
coordinating the development of current and future
standards for the interconnection of computer systems.
Network functions are divided into seven layers. Each
layer represents a group of related data processing and
communication functions that can be carried out in a
standard way to support different applications.
Open Systems Interconnection (OSI) architecture.
Network architecture that adheres to a particular set of
ISO standards that relates to Open Systems
Interconnection.
Open Systems Interconnection (OSI) reference
model. A model that represents the hierarchical
arrangement of the seven layers described by the Open
Systems Interconnection architecture.
