how many pairs of color-coded copper wires can be found within UTP cabling

4

uses duplex connector

Duplex Multimode LC Connectors

2 sources that that cause interference

EMI and RFI

little/local connector; smaller version of SC connector

Lucent Connector (LC)

what connector terminates a UTP cable

RJ45

provides better noise protection

STP

square/standard connector; widely adapted LAN and WAN connector; uses push pull mechanism to ensure positive insertion

Subscriber Connector (SC)

most common networking media

UTP

main 3 types of copper cabling

UTP, STP, coaxial

The capacity at which a medium can carry data.

bandwidth

what happens when two wires in an electrical circuit are put close together

cancellation

used for data transmission

cat 3

used for data transmission; 100mbps

cat 5

used for data transmission; 1000 mbs

cat 5e

has a separator between each wire pair

cat 6

supports 10 Gbps

cat 7

40 Gbps

cat 8

2 conductors that have the same axis

coaxial

most common cabling today

copper cabling

a disturbance caused by the electric or magnetic fields of a signal on one wire to the signal in an adjacent wire

crosstalk

method of converting a stream of data bits into a predefined code

encoding

method or pattern used to represent digital info

encoding

transmits data over longer distances and at a higher bandwidth

fiber optic cabling

measure of usable data transferred over a given period of time

goodput

amount of time it takes to go from point A to point B

latency

refers to the amount of time, including delays, for data to travel from one given point to another

latency

aqua/orange jacket

multimode

uses LED emitters

multimode

electric hardware devices, media, and other connectors that transmit the signals that represent the bits

physical components

means to transport the bits that make up a data link layer frame across the network media

physical layer

define what type of signal represents a 1 or a 0

signaling

used to represent bits on media

signaling

used for long distance

singlemode

yellow jacket

singlemode

2 types of fiber optic cabling

singlemode and multimode

locks with twist on twist off bayonet style mechanism

straight tip connector (ST)

the measure of the transfer of bits across the media over a given period of time

throughput
