Flashcards in NETWORK+ Terms J,K,L's Deck (25):
the physical placement of shorting
connectors on a board or card.
jumpered (or jumpering)
A term used to
describe devices configured via a
software utility rather than by physical
jumpers on the circuit board.
A network authentication
protocol designed to ensure that the
data sent across networks is encrypted
and safe from attack. Its primary
purpose is to provide authentication
for client/server applications.
tunneling protocol designed to
specifically tunnel point-to-point
protocol (PPP) traffic.
L2F (Layer 2 Forwarding)
A VPN protocol that defines its
own tunneling protocol and works
with the advanced security methods
of IPSec. L2TP enables PPP sessions
to be tunneled across an
arbitrary medium to a home gateway
at an ISP or corporation.
L2TP (Layer 2 Tunneling Protocol)
An IEEE specification
that provides a control method of
bundling several physical ports into
one single channel.
LACP (Link Aggregation Control
of connected computers located in a
single geographic area—usually a
building or office—that share data
LAN (local area network)
The delay induced by a
piece of equipment or device used
to transfer data
A media connector
used with fiber-optic cabling.
A protocol used to access
and query compliant directory services
systems such as Microsoft
Active Directory and Novell
A bridge that
builds its own bridging address table
instead of requiring someone to
manually enter information. Most
modern bridges are learning
bridges. Also called a smart bridge
An older computer system
A device used to
stabilize the flow of power to the
connected component. Also known
as a power conditioner or voltage
An LED on a networking
device such as a hub, switch, or
NIC. The illumination of the link
light indicates that, at a hardware
level, the connection is complete
A dynamic routing
method in which routers tell
neighboring routers of their existence
through packets called linkstate
advertisements (LSAs). By
interpreting the information in
these packets, routers can create
maps of the entire network.

A UNIX-like operating system
kernel created by Linus
Torvalds. Linux is distributed under
an open-source license agreement,
as are many of the applications and
services that run on it.
sublayer of the data link layer of the
OSI model. The LLC layer provides
an interface for network layer
protocols and the MAC sublayer.
LLC (logical link control) layer
A text file used in a
Windows network environment that
contains a list of NetBIOS hostname-
to-IP address mappings used
in TCP/IP name resolution.
addressing method used in providing
manually assigned node addressing.
logical addressing scheme
of the network to the devices that
use it, even if in physical terms the
layout of the network is different.
See also physical topology.
A continuous circle that a
packet takes through a series of
nodes in a network until it eventually
