Question 1

List five common types of Wi-Fi signal interference.

Accepted Answer

Absorption,refraction,diffraction,reflection,scattering.

Question 2

What is the difference between operating in half-duplex mode or full-duplex mode and why does it eliminate collisions?

Accepted Answer

Half-duplex communication means a station can transmit and receive data but not at the same time,much like a two-way radio.Full-duplex mode,by definition,means a NIC can transmit and receive simultaneously.Therefore,when an Ethernet NIC is operating in full-duplex mode connected to a switch,CSMA/CD isn't used because a collision can't occur in full-duplex mode.Because fullduplex mode eliminates the delays caused by CSMA/CD and allows double the network bandwidth,most Ethernet LANs now operate in this mode using switches.

Which of the following is NOT a characteristic of Unshielded Twisted Pair cabling?

Accepted Answer

A)  contains four pairs of copper wire 
B)  susceptible to electrical interference 
C)  maximum speed is 100 Mbps 
D)  comes in numbered categories
