Name:Pattawee Anantawan
Room: M.2/SR No.21
Vocabulary: Network Terms
LANA system that links together electronic office equipment,
such as computers and printers, and forms a network within an
office, building, or group of buildings
.
MAN metropolitan-area network. Network that spans a
metropolitan area. Generally, a MAN spans a larger
geographic area than a LAN, but a smaller geographic
area that a WAN
WANA communications network that uses such devices as
telephone lines, satellite dishes, or radio waves to span a larger
geographic area than can be covered by a LAN.
CAN.(1) Acronym for campus-area network. An interconnection
of local-area networks within a limited geographical space,
such as a school campus or a military base. (2) See controller
area network
PAN (1) In all capitals, PAN is short for Personal Area Network.
Based on the electric-field transmission medium, is an IBM
technology that allows individuals to exchange data with a
simple touch or grasp
PROTOCOLIn networking, a specification of the data structures
and algorithms necessary to accomplish a particular network
function
FIREWALLRouter 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.
BANDWIDTHIn 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.
GATEWAY1. A device that performs a protocol translation at
the SessionLayer or higher. 2. Archaic. A TCP/IP router that
routes packets between different network numbers.
NETWORK TOPOLOGYis the arrangement of the various
elements (links, nodes, etc.) of a computer network.[1][2]
Essentially, it is the topological[3] structure of a network and
may be depicted physically or logically. Physical topology is the
placement of the various components of a network, including
device location and cable installation, while logical topology
illustrates how data flows within a network, regardless of its
physical design. Distances between nodes, physical
interconnections, transmission rates, or signal types may differ
between two networks, yet their topologies may be identical.
An example is a local area network (LAN): Any given node in
the LAN has one or more physical links to other devices in the
network; graphically mapping these links results in a geometric
shape that can be used to describe the physical topology of the
network. Conversely, mapping the data flow between the
components determines the logical topology of the network.
BUS TOPOLOGY. A bus network is a network topology in
which nodes are directly connected to a common linear (or
branched) half-duplex link called a bus
RING TOPOLOGYA ring network is a network topology in
which each node connects to exactly two other nodes, forming
a single continuous pathway for signals through each node - a
ring. Data travels from node to node, with each node along the
way handling every packet
MESH TOPOLOGYis a network topology in which each node
relays data for the network
TREE TOPOLOGYNetwork cabling scheme in which two or
more hubs and/or data centers are connected to one another in
a succession of levels to provideredundancy. Also called
cascaded star topology or tree network
STAR TOPOLOGYare one of the most common computer
networktopologies. In its simplest form, a star network consists
of one central switch, hub or computer, which acts as a conduit
to transmit messages
SERVERA device that is shared by several users of a network
ISPInternet service provider.
DIRECTORYServices that help network devices locate service
providers
ETHERNETa system for connecting a number of computer
systems to form a local area network, with protocols to control
the passing of information and to avoid simultaneous
transmission by two or more systems
NETWORKThe infrastructure that supports electronic data
exchange.
