What is one advantage of installing a copper wire twisted-pair cable versus a fiber optic  cable?  What is one advantage of installing a fiber optic cable versus a copper wire twisted- pair cable?  2. (5 points)  What is the data transmission time to send a 2 Gbyte file over a link with a 100  Mbps line rate?  You can assume there is no overhead, so the throughput is equal to the  line rate.  Round your answer to the nearest 0.1 second and show your work.  3. (5 points)  Explain what it means for a network to be scalable.  4. (5 points)  Each numbered RFC document defines the rules of a network protocol.   What  is the title of RFC 8216 and what year was this RFC published?  5. (5 points)  Each Well-Known Port number is associated with a standard network service  application that can be offered on an Internet server.  What is the name of the network  application associated with TCP port 17?  6.  (5 points)  Describe two reasons that you would prefer to use a switched Ethernet  compared to a shared Ethernet.   7. (5 points)  What is the purpose of the ARP protocol?  8. (5 points)  The IP address of my PC is 150.8.22.16 (in dotted decimal format).   Write this  out as a 32-bit binary value.  Your answer should consist of 32 values, each of which is 0  or 1.  9. (5 points)  The MAC address of my PC is 18-6B-2C-99-DD-7A (in hexadecimal format).    Write this out as a 48-bit binary value.

1) Cable Benefits
Optical Fiber benefits
· The transmission speed is approximately 200 terabits per second. It is much faster than the coaxial cable (Guan, Yanxin, 2017).
· They do not need any amplification for transmitting data over long distances. 
· When compared with the coaxial cable we can find that optical fiber is more compact.
· It is very difficult to break into and disturb the data flow. 
· Optical fibers are less prone to lightning and do not corrode.
Coaxial Cable benefits
· Optical fiber is fast but it is not utilized mostly, so the extra cost of using fiber can be eliminated. 
· Optical fiber is not flexible. However, the coaxial cable can take all sorts of abuse, which can wreck the working of fiber. 
· Coaxial cable can be repaired by soldering or by crimp-on connectors.
· We can even send power along with the ethernet cable. 
2) Data transmission time
The formula for calculating the data transmission time is:
Amount of data / transfer rate
As per the given data, the amount of data to be transferred is 2 GB, which needs to be converted into bits.         
The transfer rate is 100 Mbps, which will be converted into bps.        
The final result will be calculated in seconds.
		2 X 109 		/	100 X 106
Data transmission time = 152.588 seconds
3) Scalable Network
Scalable network can be defined as a network, which can be started with just few nodes, but it can be expanded to multiple nodes later on (Fawcett, Lyndon, 36.12). When we scale a network, we design is as the current needs but we can expand this network in the future as the requirement changes. For example, if the demand for the network is increased by 50% in the next few years or months, then we do not need to make the changes from the scratch. Modifications can be made in the existing network system.
