Why are the pairs twisted in Ethernet cables?
To keep the pairs together
So that two separate signals can be sent at the same time
To provide data on one wire and power on the other
To reduce cross talk between wires
How many pairs of wire are their in an Ethernet cable?
Why are the pairs of wires twisted differently?
To reduce the cross talk between pairs of wires
So that each pair can be identified more easily
To make it easier to crimp the wires
No particular reason
Which one item below is NOT a benefit of using twisted pair cables?
Ease of use
Not susceptible to EMI
Which of the following is a disadvantage of using twisted pair cables?
Hard to use
Susceptible to eavesdropping
Works with the newer protocols.
What does UTP stand for?
Unconfirmed Transmission Protocol
Ultra Terminated Pair
Uniform Transmission Protocol
Unshielded Twisted Pair
