Chapter 7 Network Cabling

Question 1

UTP

Answer 1

Unshielded twisted pair cables

Question 2

STP

Answer 2

Shielded twisted pair cables

Question 3

What two qualities are we concerned about in Data wiring?

Answer 3

1) Must have a clear path way that the signal that will have enough strength to be useful.
2) We are concerned about quality of the signal. must not have any distortion.

Question 4

When a cable has a High Attenuation what will need to happen to the cable

Answer 4

It must be shorter

Question 5

Three different types of Attenuation

Answer 5

Impedance
Cable Capacitance
Crosstalk

Question 6

Impedance

Answer 6

The most important

consideration for impedance is that it remain consistent throughout the entire system

Question 7

Cable Capacitance

Answer 7

Data transmissions are square-wave
signals. When the capacitance is too great, it has a tendency to round off the digital
data signals, making it more difficult to receive.

Question 8

Crosstalk

Answer 8

the amount of signal that is picked up by a quiet conductor from other conductors that are conducting data. This signal is picked up through electromagnetic induction, the same principle by which transformers operate.

Question 9

Different Types of Network Cabling Types

Answer 9

Unshielded Twisted Pair (UTP) 22-24 Gauge
Screened Twisted Pair (ScTP)
Shielded Twisted Pair (STP) Cables, 22–24 Gauge
Optical Fiber Cables
