Vocabulary
Bandwidth
Transmission capacity of a communications channel-an analog channel typically
measured in hertz (Hz); high bandwidth can carry more data than a low bandwidth
channel
Broadband
High bandwidth communications systems, such as cable TV and DSL are sometimes
referred to as broadband
Narrowband
Low bandwidth systems that have less capacity to transmit data, such as a telephone
system
Protocol
Set of rules for efficiently transmitting data from one network node to another
Network functions performed with protocols:
Dividing messages into packaging
Affixing addresses to packets
Initiating transmission
Regulating the flow of data
Checking for transmission errors
Acknowledging receipt of transmitted data
Client/Server network
Contains one or more computers configured with server software and other computers,
configured with client software, that access the servers. Server provides a centralized
repository for data and a transfer point through which data traffic flows
Peer-to-Peer Network
P2P-Treats every computer as an equal so that workstations can store network data,
which can be transported directly to other workstations without passing through a
central server-forms the basis for file sharing networks
Ethernet
(Defined by IEEE 802.3) simultaneously broadcasts data packets to all network devicesrefers to a family of LAN technologies that offer various data transmission rates over
fiber-optic and twisted-pair cables arranged in a star or bus topology

Physical Topology
Arrangement of devices in a network
Star Topology
Has a central connection point for all workstations and peripherals. Central connection
is not necessarily a server-can be a hub which will broadcast data to workstations and
peripherals (many homes use Star topology)
Ring Topology
Connects all devices in a circle, with each device having only two neighbors. Data is
transferred in a circle around the ring (infrequently used in today’s technology)

Bus Topology
Uses a common backbone to connect all network devices-works best with fewer
devices-if backbone fails-network unuseable (network plan was based on a bus
topology)
Mesh Topology
Connects each network device to many other network devices-has many routes for
information to travel-if one route is down, information can travel another route (original
plan for the Internet was based on mesh topology)
Tree Topology
Blend of star and bus networks-multiple star networks are connected into a bus
configuration by a backbone (schools and businesses)
Repeater
Hub that can boost the strength of the signal that carries data over any network
topology when the distance between two nodes exceeds the carrying capacity of their
connecting links
Node
Each connection point on a network. A network node typically contains one of the
following devices:
Server-computer responsible for storing data and programs
Workstation-personal computer connected to a network
Networked peripheral-devices such as printer or scanner directly connected to
a network rather than to a workstation
Network device-an electronic device that broadcasts network data, boosts
signal, or routes data to its destination
Bridge
Device that connects two similar networks-simply transfers data without regard to its
format
Hub
Network device designed to broadcast data to workstations and peripherals-anything
that comes in one port is sent out to all the others-okay for small networks
Router
Electronic device that joins two or more networks-example: a home network can use a
router and a DSL or cable modem to join the home’s LAN to the Internet’s WAN
Switch
Gateway
similar to a hub, but more efficient-it pays attention to the traffic-most of the network
traffic only goes where it needs to rather than to every port-can be faster
Device that connects different topologies and technologies; Generic term for any device
or software code used to join two dissimilar networks by converting data sent from one
network into a format compatible to the receiving network
Wired Network
A network where data travels from one device to another over cables
Wireless Network
A network where data travels through the air, eliminating the need for cables
Twisted-pair Cable
Designed for telephone and network installations: STP-shielded twisted pair; UTPunshielded twisted-pair; use RJ-11 plugs for telephone or RJ-45 plugs for computer
networks
Cable categories (CAT) indicate carrying capacity: CAT-1 is sufficient for telephone
cabling, CAT-5 provides more capacity for networking
Bundle of optical fibers that miniature lasers convert data into pulses of light that flash
through the cables
Fiber-optic Cable
