-
The total throughput capacity of a network link or segment.
BANDWIDTH
-
a single binary digit, either a 0 {off} or 1 {on}
BIT
-
A device used to connect two LAN's or segments of a LAN, so communication is possible without a router. Bridges can connect only networks running the same protocol.
BRIDGE
-
A set of all devices receiving broadcast frames originating from any device within the set – for example, all devices in a VLAN.
BROADCAST DOMAIN
-
a type of network design in which all devices are connected to central cable.
BUS TOPOLOGY
-
Eight binary bits. There are 256 unique combinations, from 00000000 to 11111111 {0 to 255 in decimal.}
BYTE or OCTECT
-
A section of the network where nodes compete for access to same physical transmission medium. This conflict often results in a frame sent by one node's NIC colliding with a frame sent by another NIC in the same collision domain.
COLLISION DOMAIN
-
The capability of a communications device to concurrently send and receive data.
FULL DUPLEX
-
The capability for data transmission between sending and receiving stations in both directions, but only one at a time.
HALF DUPLEX
-
A _________ is a computer connected to the network.
HOST or WORKSTATION
-
A device that serves as a common connection point for multiple devices on a network. It receives signals and forwards them to all the devices connected to it.
HUB
-
An ___________ is a numeric identifier that represents a computer or device on a TCP/IP network.
IP ADDRESS
-
A _______ is a computer network confined to a relatively small area such as a single floor, building, or campus.
LAN or LOCAL AREA NETWORK
-
a unique 48–bit identifier written as 12 hexadecimal characters grouped in pairs and hard–coded in the NIC.
MAC ADDRESS
-
A LAN covering multiple buildings where the building–to–building links are owned and controlled by a service provider, usually because of public streets and spaces separating the buildings.
MAN or METROPOLITAN AREA NETWORK
-
a physical environment through which signals pass.
MEDIA
-
network topology in which each node on the network has a connection to every other node on the network.
MESH TOPOLOGY
-
A __________ is two or more computers connected together to share resources.
NETWORK
-
Four binary bits from 0000 to 1111 {0 to 15}. It is used in hexadecimals.
NIBBLE
-
Adapter that provides the physical connection to send and receive data between the computer and the network media.
NIC or NETWORK INTERFACE CARD
-
A __________ is defined as any device that connects to the network that has a recognized address.
NODE
-
a formal set of rules describing data transmission, especially across a network.
PROTOCOL
-
a set of related communications protocols operating as a group to address communication at some or all of the seven layers of the OSI Reference Model.
- TCP/IP is a protocol stack implementing the OSI model.
- PROTOCOL SUITE or STACK
-
a networking configuration where all nodes are connected in a circle with no terminated ends on the cable.
RING TOPOLOGY
-
A device that receives and sends data packets between two or more networks.
ROUTER
-
Devices and connection that can send data in only one direction. a sensor circuit is an example
SIMPLEX
-
a network layout where each node on the network is connected to a center hub.
STAR TOPOLOGY
-
Shielded Twisted Pair Cabling
STP CABLING
-
A Layer 2 device typically containing numerous ports for node connections that filters and forwards packets between LAN segments.
SWITCH
-
The rate of successful data delivery over a communication channel.
THROUGHPUT
-
the configuration or layout of the wiring of a network.
TOPOLOGY
-
A commonly used, inexpensive, and relatively low–speed transmission medium consisting of two insulated wires wound about one another. The wires can be shielded or unshielded.
TP CABLE or TWISTED PAIR CABLE
-
Device or interface that translates the light signals on the fiber to electrical signals for copper cabling and vice versa.
TRANSCEIVERS
-
Unshielded Twisted Pair Cabling
UTP CABLING
-
Two or more LANs connected by a link across a large geographical area.
WAN or WIDE AREA NETWORK
