Computer Science Homework Help

Students will explain, in detail, how data is transferred to and from an Internet-enable device at their home to towson.edu.
The project requires each student to detail protocols, media,
optimization schemes, software, and hardware on both the home device and
towson.edu that produce a smooth exchange of information.

Consider the following graphic from Module 2 – Protocols.pptx (slide 30) TCP IP Example with a Router.png

For your project, you should create the graphic (TCP IP Example)
using the OSI Reference Model. The diagram should identify the protocol
used at each layer of the OSI model on both the transmitting (you) and
receiving end (www.towson.edu). Instead of Network 1 and Network 2, you should create a separate diagram to illustrate each “node” (appliance/router/satelite/microwave/switch)
during the request. This second diagram should illustrate what
physical items (nodes) were instrumental in assisting your request.
Please use the results of tracert/traceroute to
support the nodes in your diagram. You will most likely need to assume
and make educated guesses to determine what nodes were utilized.

For this project, you must consider all of the following.

• A diagram of the OSI model and the utilized protocols to handle the request from your internet-enabled device to towson.edu (4 pts)
  • Include all of the communications protocols used in the process
• A diagram of the nodes used to coordinating your request to the destination (www.towson.edu) (3 pts)
  • Explain the various communications signals (digital/analog) and media (guided/unguided) used in the process in your writeup
• List the multiplexing and modulation techniques (2 pts)
  • Realize that natively, some media/signals utilize multiplexing/modulation
  • This should be included in your write-up – Example: Ethernet and WiFi perform….????… type of multiplexing/modulation
• List all of the hardware/software used to perform the task (2 pts) which should support your node diagram
  • The following commands may be helpful: ping, nslookup, whois, tracecrt/traceroute
  • Use tracert or traceroute to determine the most likely path to towson.edu
  • If using the iPhone consider the Ping – Manage Engine [https://itunes.apple.com/us/app/manageengine-ping-tool/id460362949?mt=8]
• Identify two nodes in the explained process for your
  scenario, outline an improvement implemented in each and the impact to
  the communication. (5 pts)
• The submission must be at least 6 pages double-space, at
  least 3000 words, and include all of the above information and the
  following:
  • Network Diagram using Visio (FREE under Dreamspark – https://e5.onthehub.com/WebStore/ProductSearchOfferingList.aspx?srch=visio&ws=a1ca0c1e-c79b-e011-969d-0030487d8897&vsro=8) or GNS 3 (FREE – https://www.gns3.com/)
  • OSI model applied to the protocols used in the processing of information transmission
  • Every page under 6 will be a 10 point deduction up to 15 points – Max 2.5 pages of visuals
• There is a 3000 word minimum so explain all diagrams,
  lists, and nodes thoroughly- (2500 – 2999 words [-5], 2000-2499 words
  [-10], <2000 words [-15]
