LAN Local –area network
The network administrator talked with great
enthusiasm about upgrading the LAN to Gigabit Ethernet.
MAN. Metropolitan area network metropolitan area network (MAN) is a network
that interconnects users with computer resources in a geographic area or
region larger than that covered by even a large
WAN wide area network
The technical college's WAN connected all the county
campuses.
CAN.campus area network
PAN Personal area network
PROTOCOL Protocol
In networking, a specification of the data structures and algorithms necessary to accomplish a particular network
function.
FIREWALL Firewall
Router or access server, or several routers or access servers, designated as a buffer between any connected
public networks and a private network. A firewall router uses access lists and other methods to ensure the
security of the private network
BANDWIDTH Bandwidth
In analog communications, the difference between the highest and lowest frequencies available in the band. In
digital communications, bandwidth is loosely used to refer to the information-carrying capacity of a network or
component of a network.
GATEWAY Gateway
1. A device that performs a protocol translation at the SessionLayer or higher. 2. Archaic. A TCP/IP router that
routes packetsbetween different network numbers.
NETWORK TOPOLOGY The physical topology of a network is the actual geometric
layout of workstations. There are several common physical topologies, as described below and as
shown in the illustration.
BUS TOPOLOGY. In the bus network topology, every workstation is connected to a main
cable called the bus. Therefore, in effect, each workstation is directly connected to every other
workstation in the network.
RING TOPOLOGY In the ring network topology, the workstations are connected in a
closed loop configuration. Adjacent pairs of workstations are directly connected. Other pairs of
workstations are indirectly connected, the data passing through one or more intermediate nodes.
MESH TOPOLOGY The mesh network topology employs either of two schemes, called
full mesh and partial mesh. In the full mesh topology, each workstation is connected directly to each
of the others. In the partial mesh topology, some workstations are connected to all the others, and
some are connected only to those other nodes with which they exchange the most data.
TREE TOPOLOGY The tree network topology uses two or more star networks
connected together. The central computers of the star networks are connected to a main bus. Thus,
a tree network is a bus network of star networks.
STAR TOPOLOGY Star Topology
LAN topology in which end points on a network are connected to a common central switch by point-to-point links.
A ring topology that is organized as a star implements a unidirectional closed-loop star, instead of point-to-point
links. Compare with bus topology, ring topology, and tree topology.
SERVER Server
A device that is shared by several users of a network
ISP A directory is an organizational unit, or container, used to organize folders and files
into a hierarchical structure. Directories contain bookkeeping information about files that are,
figuratively speaking, beneath them in the hierarchy. You can think of a directory as a file
cabinet that contains folders that contain files. Many graphical user interfaces use the term
folder instead of directory.

ETHERNET Ethernet
A specification for a transmission system including Layers 1 and2 of the OSI 7-layer model using the CSMA/CD
access method.In common usage, "Ethernet" refers to both the DIX (DEC - Intel - Xerox) version of this
specification or to the IEEE version, moreformally known as "802.3". The DIX version is distinguished bythe
reference "Ethernet V.2".
NETWORK Network
The infrastructure that supports electronic data exchange
