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
