Answer to Question #230260 in Computer Networks for yogesh chhetri

Question

Assume that Sam wants to send a video and audio file related to their lecture notes to his friend

Bob who is away from university. Illustrate how a message is transmitted from the Sam’s

network to the Bob’s network in the Internet model of a data communication network.

Illustrate how the bit pattern 10110011 would be sent using

a. Unipolar signaling

b. Return to zero signaling

c. Amplitude Modulation (AM)

d. Frequency Modulation (FM)

e. Phase Modulation (PM)

Answer 1

 how a message is transmitted from the Sam’s

network to the Bob’s network in the Internet model of a data communication network.

When this message is transmitted across the network, its first broken down into segments that are then placed into containers known as packets by the internet protocol. The IP is responsible for delivering these packets from source to destination. Packets uses some form of addressing to uniquely identify the message source and destination.

how bit pattern 10110011 is sent using

a. Unipolar signaling

in Unipolar signaling, the presence of pulse represents a 1 and the absence of pulse represents a 0

b. Return To zero signaling

In amplitude modulation, the information signal is used to vary the amplitude of the carrier sine wave.

c. Amplitude Modulation (AM)

In amplitude modulation, the information signal is used to vary the amplitude of the carrier sine wave.

d. Frequency Modulation (FM)

frequency modulation happens when there is varying frequency of the carrier with the info signal.

e. Phase Modulation (PM)

phase modulation happens when there is Varying the phase angle of the carrier with the info signal.
