Front 6

coaxial cable

Back 6

Physical transmission media that consists of

a single copper wire surrounded by at least

three layers: (1) an insulating material, (2) a

woven or braided metal, and (3) a plastic

outer coating. Also called coax.

Front 7

communications software

Back 7

Programs and apps that (1) help users

establish a connection to another

computer, mobile device, or network; (2)

manage the transmission of data,

instructions, and information; and (3)

provide an interface for users to

communicate with one another

Front 8

communications satellite

Back 8

A space station that receives microwave

signals from an earth-based station,

amplifies (strengthens) the signals, and

broadcasts the signals back over a wide

area to any number of earthbased stations.

Front 9

communications device

Back 9

Hardware capable of transferring items

from computers and devices to

transmission media and vice versa.

Front 10

Ethernet

Back 10

A network standard that specifies no

central computer or device on the network

(nodes) should control when data can be

transmitted.

Front 11

Fiber-optic cable

Back 11

Physical transmission media that consists of

dozens or hundreds of thin strands of glass

or plastic that use light to transmit signals.

Front 12

Home network

Back 12

Multiple computers and devices connected

together by home users.

Front 13

IrDA

Back 13

Infrared Data Association; standard for

devices to transmit data wirelessly to each

other via infrared (IR) light waves.

Front 14

Local area network (LAN)

Back 14

A network that connects computers and

devices in a limited geographical area such

as a home, school, office building.

Front 15

Microwaves

Back 15

Radio waves that provide a high-speed

signal transmission.

Front 16

Network

Back 16

A collection of computers and mobile

devices connected together, often

wirelessly, via communications devices and

transmission media.

Front 17

NFC

Back 17

Type of wireless connection that uses closerange

radio signals to transmit data

between two NFC-enabled devices.

Front 18

Personal area network (PAN)

Back 18

A network that connects computers and

devices in an individual's workspace using

wired and wireless technology.

Front 19

T-carrier line

Back 19

Any of several types of long-distance digital

phone lines that carry multiple signals over

a single communications line.

Front 20

TCP/IP

Back 20

Network protocol that defines how

messages (data) are routed from one end

of a network to the other, ensuring the

data arrives correctly. Short for

Transmission Control Protocol/Internet

Protocol.

Front 21

Twisted-pair cable

Back 21

Physical transmission media that consists of

one or more twisted-pair wires bundled

together.

Front 22

Token ring

Back 22

Standard that specifies that computers and

devices on the network share or pass a

special signal, called a token, in a

unidirectional manner and in a preset

order.

Front 23

UWB (ultra-wideband)

Back 23

A network standard that specifies how two

UWB devices use short-range radio waves

to communicate at high speeds with each

other.

Front 24

Wireless LAN (WLAN)

Back 24

A LAN that uses no physical wire

Front 25

Wide area network (WAN)

Back 25

A network that covers a large geographic

area (such as a city, country, or the world)

using a variety of wired and wireless

transmission media.

Front 26

Wi-Fi

Back 26

Broadband Internet connection that uses

radio signals to provide connections to

computers and devices with built-in Wi-Fi

capability or a communications device that

enables Wi-Fi connectivity.
