Network Design Paper
The school has recently acquired a building in Maryland. This new building will house some admin offices, lecture rooms, and computer labs.
Building Dimensions:
Length: 240 feet
Width: 95 feet
Height: 30 feet
The building has 2 stories with layouts that I can attach for you.
There are 6 computer labs that will be used for instruction. Each of the labs will have 21 computers (20 for students 1 for instructor). Each of these labs will also have a server in the closet located inside the lab.
I addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students to do their homework. There will be 30 computers in this lab and a server in the closet.
The library will also have some computers to allow students access to the library resources. There will be 10 computers for student’s use in the library, and 5 computers for Library Staff.
There are 5 lecture classrooms in the building. Each room will have a computer for instructor use.
Finally, there are various offices in the building. Each of these offices will have 1 computer for staff use, with the exception of the Admission office that will have 5 computers for staff use.
 

2 server rooms have been allocated, 1 on the first floor, and 1 on the second.
Your task is to design the network for this new building with the following criteria:
Student-accessed computers should be on separate network from staff accessed computers.
The whole building will share one internet access connection (T-1 link from Verizon). This connection will come into the Server room on the first floor.
Security is very important and this school.
The network will be assigned the 10.15.0.0 network address for all computers and devices. For internet routing use 191.1.1 network address.
The network should use physical cable (not wireless), but do provide wireless access in the Student Lobby Area.
 

Submission should include no more than 3 pages, excluding diagrams and references.
1. Define the subnet (based on :rooms, floor, department, or other criteria.)
2. For each subnet, define the network address, subnet mask, and available IP addresses to be used by computers or devices.
 

Physical Address Design:
1. Define the topology that will be used.
2. Select the appropriate network media to use.
3. Select the appropriate network connecting devices to use.
4. Physical layout of computers on the floor plan.
5. List of additional servers or network devices needed to implement the network.
6. Justifications for your network design (number 1-5 above).
You will be evaluated by your ability to implement appropriate IP addressing scheme.
Select and justify appropriate cable media that includes the length of each cable segment and number of nodes in each segment.
Select and justify appropriate topology such as star, bus, or ring for your netowork.
Select and justify your selected network equipment.
Select and justify appropriate network services to meet network requirements.
Select and justify implementation of the network.
use proper grammar, formatting, network terminology, and reference citations.
Feel free to use any drawings or attachments, and assume any number of computer or users.

Assignment Overview

Write a program for a real estate agent. The program should perform the following tasks:

1. Create an array to hold average house price for the each of past 25  years for a single family residence of 1500 square feet. Initialize the  array with the values in sorted order, assuming the average house price  increases each year.

   Prompt the user for a house value.

2. Use a binary search algorithm to determine the year that most  closely matches the house value entered by the user and display the year  and average house value for that year.

   After you finish the program, submit the source code and a screen shot of the output.

Assignment Expectations

1. Use proper data structure to solve programming task.
2. Demonstrate your knowledge of searching using the binary search algorithm.

Required Reading & Resources

Binary Search (n.d.). Retrieved from http://leepoint.net/algorithms/searching/binarysearch.html

1. Read content resources. Select the following link to the Worldfavor article(https://blog.worldfavor.com/an-overview-of-corruption-in-supply-chains), An Overview of Corruption in Supply Chains. Read the article and then click on the Blockchain link to see how major companies are using technology to provide transparency in their global supply chains.
2. Write an initial response to the following key question(s) or prompt(s):
   1. Considering the nature of your PBL project’s company, what do you see as major advantages of Blockchain to assist it in avoidance of corruption?
   2. Why is transparency in the entire supply chain from providers of raw materials to the customers’ purchases in their local box stores so important to protect your company’s corporate image and its integrity?
3. The World Bank stated that corruption is one of the largest contributors to the economic well-being of developing countries. It is also the single biggest cause of business failure. With the growing global competition, governments and business organisations are coming up with solutions to combat corruption. But some argue that corruption is here to stay and they will have to adapt to it (Ibodullaevich & Kizi, 2021). What do you think?

Prompt

Last week, we all got some experience working with modeling, specifically with ArchiMate. We showed a chosen business from three different core layers: business, application, and technology. However, we can dive much deeper using viewpoints to show specialized diagrams tailored to unique perspectives and stakeholders. The three core layers are actually considered basic viewpoints in and of themselves. In this week’s discussion, we’ll look at some other more specialized viewpoints.

For the company you selected last week, select a viewpoint and present your company from that viewpoint. For a full list of viewpoints and examples, refer to the textbook or visit Full ArchiMate Viewpoints Guide. (Links to an external site.)

Attach your viewpoint as a jpg image to the main post. (Select the Embed Image icon from the box above your discussion reply.) Then, provide 100-word minimum post explaining your thoughts on your company, their process, your experiences using a modeling language, and how such diagrams can be useful and usable.

Response Parameters

• Initial responses due by Friday at 11:59 p.m. ET
  • Posts should be 100 words minimum in length with a diagram
  • Use APA formatting to cite all of your sources − Purdue Writing Lab (Links to an external site.)
  • Access Evans Library for articles and journals (Links to an external site.)
