Questions:

Question 1: Signals travel through imperfect transmission media, describe in detail the three main causes of impairments. Answer MUST include how they affect different characteristics of signals including amplitude, phase and frequency.
Question 2: A host is sending a file from a PC using FTP. Explain the process the PC undertakes, between the time the application begins sending the file and the electrical signals leave the 100BaseT interface card. Make sure to clearly discuss what happens at each layer of the TCP/IP Model described in the textbook.
Question 3: Calculate the approximate bit rate and signal level(s) for a 3 MHz bandwidth system with a signal to noise ratio of 110?
Question 4: Compare the link local address to unique local address in IPv6. Discussion MUST include a comparison to private addresses in IPv4.
Question 5: Compare ICMPV4 and ICMPV6 protocols. Describe the different types of errors reported by the ICMPV6 Error-Reporting messages.
Question 6: What is a Decentralized P2P Network and how is it different from a centralized P2P network? List and describe the two different types of decentralized P2P network?

Answers:

Answer to Question 1:
Signals go through the transmission media that has not been appropriate. The defect results in signal impairment. This implies the flag toward the starting of the medium was not similar as the flag toward the ending of that medium. What has been sent is not been what received. Three reasons for such impairment have been:

Attenuation
Distortion

Attenuation: It indicates the loss of the energy. The signal is weak. As signal transmits via any medium, energy is lost. This happen due to the overcoming of the resistance the medium has been possessing. The amplifiers have been utilized for compensating such loss of the energy. This is done by the amplification of the signal (Hecht, 2015).
Measurement of attenuation:
For displaying the gain or loss of the energy, the “decibel” is used as the unit.
dB = 10 log10 P2/P1
P1 is the input signal
P2 is the output signal.
Distortion: It indicates that the signals have been altering its shapes and forms. The distortion takes place in the composite signals. Every frequency component posses its individual speeds of propagation while transmitting by any medium. The various components reach with various delays towards the receiver as a result of this. This indicates that the signals acquire various phases at the receiving end than they have been doing at the origin.
Noise: There have been various types of noises. The thermal noise is the random noise of the electrons within the wires. It creates additional signals. The induced noise has been acting as the transmitting antenna and the receiving antennae (Geier, 2015). It is done from the appliances and motors. The crosstalk noise is same as the previous but there are two wires present. The impulse noise is the spikes originating from the lightning, power-lines and others.
Answer to Question no 2:
For the Ethernet arranges needing large transmission speeds, the Fast Ethernet standard is set up. This standard has been rising the Ethernet speed restrain from 10 Megabits for each second (Mbps) to 100 Mbps with just negligible alteration in the current cable structure. There have been three sorts of Fast Ethernet. They are the BASE’S TX, 100BASE-FX and 100BASE-T4. The last one uses an additional two wires for usage with the level 3 UTP cable. The 100BASE-TX standard has turned into the most prominent because of its nearby similarity with the “10BASE-T” standard of Ethernet (Comer, 2015). For the system manager, the joining of Fast Ethernet into a current arrangement exhibits a large group of choices. Managers must decide the quantity of clients in every site over the system. It requires larger throughput.  They should further choose which sections of the base, should be reconfigured particularly for 100BASE-T. Then afterward they must pick the essential equipment to join the 100BASE-T fragments with the already present 10BASE-T portions. Gigabit Ethernet has been the further innovation that guarantees a relocation way better than the Fast Ethernet (Petite, 2015). This is done so that the upcoming era of networks would bolster much higher data exchange speeds.
Answer to Question no 3:
The “Shannon’s Theorem” provides an upper bound to the limit or capacity of a connection, in bits every second (bps), as a function of the bandwidth available and the “signal-to-noise” ratio of the connection.
The Theorem can be expressed as:
C = B * log2 (1+ S/N)
C = achievable capacity of the channel,
B =bandwidth of line= 3MHz (given),
S = average of the signal powers
N = average of the noise powers.
∴ C= 3* log2 (1+ 110) [? S/N= 110, given]
= 20.72 (approximately)
Answer to Question no 4:
At whatever point may the configured IP setup, through the DHCP becomes gets failed, the Windows has been consequently performing the auto-configuration addressing. This is done from the range 169.254.0.1 to utmost 169.254.255.254. This enables the PC to interact with different other machines on the connection. In IPv6, the addresses of link-local start with 1111111010 (Goyal & Arora, 2017).
Not at all like site-local addresses, are the link-local addresses never sent by the routers.  It must be accordingly reaching the link only. This is the motivation behind why the following 54 bits are set to 0. The last 64 bits are set arbitrarily by the working framework.
There is a vital contrast between IPv6 and “IPv4 APIPA” addresses. Once any computer gets an address of IPv4 from the DHCP server, the APIPA is not reachable any more. In any case, with IPv6, a system interface dependably possesses “link-local address”. This is on the off chance that another IPv6 address is allocated manually. It might also take place as the NIC gets an address of IPv6 address from the DHCP server. This implies PCs on a connection can simply impart through IPv6 utilizing the addresses of “link-local” (Gont, 2014). This has not been in the situation of IPv4. It happens on the grounds that APIPA locations are not in an indistinguishable subnet from the private or open IPv4 addresses. Along these lines, if the neighborhood DHCP is inaccessible, the PCs can in any case get access to the local services. This is done through IPv6. This, however do not have the capacity to reach Internet or the services in the other links.
Answer to Question no 5:
The primary meaning of ICMP has been supporting the “Internet Protocol Version 4” or IPv4 systems. The IPv6 includes an upgraded format of the protocol popularly called the ICMPv6 (Rosen, 2014). This is done to separate this from the first ICMP or the ICMPv4.
The different types of error reporting messages are:
“Destination Unreachable” message: This generates from the router or source host during any congestion.
“Packet too big” message: It originates from router. This occurs when a packet is not forwarded to next loop.
“Parameter problem” message: It has been related to mistakes of the header of IPV6 (Yadav, 2015).
Answer to question no 6:
On the basis of the “grid-model”, the decentralized P2P system is the set of applications running on various computers. The machines have been interconnected to perform any task remotely.
The approach of decentralized network has a tendency to be more powerful. Yet it is generally precarious to make it as productive as the centralized approach. Regarding adaptability, decentralized methodologies have greater potentials. However it is not insignificant to ensure that any given decentralized framework has been really scaling well from both the hypothetical and functional perspectives (Gavaldà-Miralles et al., 2014).
The two kinds of decentralized P2P networks are the unstructured and the structured.
An unstructured system contains peers that are arbitrarily interfacing with some subset of all the peers. This is a straightforward approach (Kamimura, Tomita & Kurokawa, 2013). However is has not been scaling well. On the other side, the structured networks have been designed for efficient searching. Overlooking the churns, finding a bit of information among the millions of companions has been simple here.
