Explanation / Answer

Solution 1:

Answer = (D) ATTENUATION

Attenuation is term used for loss of signal strength or energy

Noise is unwanted interference in signal transmission

Amplification is opposite of Attenuation which means increase in signal energy

Distortion is the change in the real form of something.

Solution 2:

Answer= (A) Unicast

To check the address type, First we have to check the second hexadecimal digit from the left. If it is even digit, the address is Unicast. If it is Odd digit, the address is Multicast. If all are Fs, the address is Broadcast.

For the given Address 4C:12:20:23:10:1B

Second hexadecimal digit is C which is 1100 in binary i.e. even

So the address is of Unicast type.

Solution 3:

Answer = (A) left to right, byte by byte - each byte being sent right to left bit by bit.

i.e for each byte LSB is sent first and the MSB is sent last

MSB = Most Significant Bit

LSB = Least Significant Bit

Solution 4:

Answer = (A) Packet Sniffer

Wireshark is a packet sniffing tool. It registers the packets travelling..
