Front 1

Token Ring

Back 1

Network standard in which computers and devices on the network share a special signal, called a ______, in a unidirectorial manner and in a preset order

Front 2

Ethernet

Back 2

Network standard that specifies no central computer or device on the network should control when data can be transmitted. controls access to network by requiring devices to pass a special signal called token.

Front 3

802.11 (Wi-Fi)

Back 3

family of standards for wireless LANS (Look at Graph of 4 different transfer rates)

Front 4

Router

Back 4

Communications device that connects multiple computers or other ______ together and transmit data to its correct destination on a network

Front 5

hub

Back 5

device that provides central point for cables in network

Front 6

Fiber optic cable

Back 6

Dozens or hundreds of thin strands of glass or plastic that use light to transmit signals. Less Susceptible to interference (noise) and, therefore, more secure, smaller size (thinner and lighter) capable of carrying significantly more data at faster speeds than wire cables

Front 7

Twisted-pair

Back 7

Cable used for telephone systems and network cabling consists of one or more ______ wires bundled together

Front 8

Coaxial Cable

Back 8

A single copper wire surrounded by at least three layers: (1) an insulating material, (2) woven or braided metal, and (3) plastic outer coating.

Front 9

T-carrier line

Back 9

Is any of the several types of long distance digital telephone lines that carry multiple signals over a single communications line. A standard dial-up telephone line carries only one signal, _____ lines use multiplexing so that multiple signals can share the line. Very fast and expensive. __1 and __3 lines.

protocol

Back 10

Standard that outlines characteristics of how two network devices communicate.

Front 11

Node

Back 11

Term used to refer to each computer or device on a network

Front 12

Latency

Back 12

the time it takes a signal to travel from one location to another on a network

Front 13

ISDN-(integrated services digital network)

Back 13

set of standards for digital transmission of data over standard copper telephone lines. Uses multiplexing.

Front 14

Topology

Back 14

layout of computers and devicesin a communications network, three commonly used network _______ are bus, ring, and star. Bus- single central cable. Ring- cable forms a closed loop. Star- All nodes connect to central device like a hub or a switch, forming a star.

Front 15
