Question 1

Noise or interference Kinda green or destroy the signal on a network is measured in

Answer 1

DB loss

Question 2

This is caused by motors powerlines TVs copiers etc.

Answer 2

Emi

Question 3

This occurs when a Signal traveling on one wire or cable interferes with the signal traveling over and adjacent wire or cable

Answer 3

Crosstalk

Question 4

Cross talk that occurs between two cables

Answer 4

Alien Crøss Talk

Question 5

Crosstalk that occurs between wire pairs near the source of a signal

Answer 5

NEXT near end cross talk

Question 6

Cross talk measured at the far end of the cable from the signals source

Answer 6

FEXT far end cross talk.

Question 7

Another transmission floor is – – – – – or the loss of a signal strength as it travels away from the source

Answer 7

Attenuation

Question 8

To compensate for attenuation signals are boosted in route using a – – – – – which Regenerate a Digital signal in its original form without the noise it might have previously accumulated

Answer 8

Repeater

Question 9

the most common way to measure latency on data networks is calculating the _________

Answer 9

round trip time

Question 10

Latency causes problems when receiving nude is expecting some type of communication such as the rest of Datastream it has begun to accept if packets experience varying amounts of delay they can arrive out of order a problem commonly called

Answer 10

Jitter

Question 11

Also called duplex the signals are free to travel in both directions over a medium simultaneously as an Analogy talking on the telephone is a duplex

Answer 11

Full duplex

Question 12

Signals may travel in both directions over a medium but in only One Direction at a time

Answer 12

Half duplex

Question 13

Signals may travel in only One Direction and this is sometimes called One Way or uni directional communication

Answer 13

Symplex

Question 14

You can choose full duplex have to plugs or auto negotiation which allows the nick to select the best blank speed and duplex that is also supported by a neighboring device however if you specify a particular speed and duplex that is not supported by the neighboring device the result is a —————- and therefore slow end Failed transmission

Answer 14

Speed and duplex mismatch

Question 15

A form of transmission that allows multiple signals to travel simultaneously over one medium is known as

Answer 15

Multiplexing
