Network Design Paper UMUC has recently acquired a building in Frederick, Maryland. This new building will house some administrative offices, lecture rooms, library, and computer labs. Building dimensions: Length: 240 Feet Width: 95 Feet Height: 30 Feet The 40-year-old two-story building has the following existing layout: There will be six computer labs that will be used for instruction. Each of these labs will have 21 computers (20 student computers and 1 instructor computer). Each of these labs will also have a server in the closet located inside the lab. In 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 five lecture classrooms in the building. Each of this room will have a computer for instructor’s use. Finally, there are various offices in the building. Each of these offices will have one computer for the staff use, with the exception of the Admission office that will have 5 computers for staff use. Equipment Inventory Workstation Placement Number of Workstations Users Total WS 6 Instructional Computer labs 21 WS Student and Instructor 132 WS (based on 20 WS for students and 1 WS for instructor on each lab) Student Computer Lab 30 WS Student 30 WS 5 various offices 5 WS Staff 5 WS Admission office 5 WS Staff 5 WS Library 10 WS Student 10 WS Library 5 WS Staff 5 WS Server Staff To be determined by students Network Connecting Devices IT Staff To be determined by students Printers To be determined by student Two server rooms have been allocated, one on the first floor and one on the second floor. Your task is to design the network for this new building with the following criteria: • Student-accessed computers should be on separate network from the 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 for UMUC as we have to protect students and employees data as well as any intellectual property that UMUC has on the servers and computers. • The network has been 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 (in no more than three pages, excluding diagrams and references): Network Addressing: 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 Network 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 the 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 on your ability to o Implement appropriate IP addressing scheme o select and justify appropriate cable media that includes the length of each cable segment and number of nodes on each segment o select and justify appropriate topology such as star, bus, or ring for your network o select and justify of your selected network equipments o select and justify appropriate network services to meet network requirements o select and justify security implementation for the network o use proper grammar, formatting, network terminology, and reference citations Feel free to use any drawings or attachments, and assume any number of computers or users (not when provided here). You will be graded on the basis of right media, topology and knowledge of network concepts.

Psychological Underpinnings: A Task at Hand (Benchmark Assignment)
i) Review the psychological and cognitive theories presented throughout the course. Conduct a task analysis for two of the following tasks. Choose one of the following from the Physical Tasks list and one from the Academic Tasks list. In order to correctly task-analyze the procedures below, the student should perform the task and document each individual step using specific details.
(1) Physical Tasks
(a) Tying a shoe.
(b) Jumping rope.
(2) Academic Tasks
(a) Solving a two-digit addition math problem.
(b) Decoding the word dog.
ii) Using the task analysis breakdown from the above categories, create lesson plans that clearly outline the step-by-step procedures for each task selected. The lesson plans should each contain the following components at a minimum:
(1) Objective (the academic objective needs to be directly connected to state academic standards, but the physical objective does not).
(2) Materials needed to teach the lesson.
(3) Clear step-by-step directions/procedures.
(4) An assessment of learning that is clearly described.
iii) Using the lesson plan created, teach the above two tasks to a younger family member or child of a friend and compare which was easier for the child to learn. Create a table that compares the two lessons.
iv) Write a 1250-1500-word essay explaining the following:
(1) The psychological/cognitive theorists relating to the task analysis (support all of your claims and observations with solid references and details).
(2) The task analysis process, its pros/cons, and how you used it for each step of this activity,
(3) Your observations of the effectiveness of your lesson plan as it relates to the success (or failure) of the lesson with the learner(s).
(4) Three self-suggestions for improving the process.
v) Use standard essay format in APA style, including an introduction, conclusion, and title page. An abstract is not required. Cite in-text and in the References section.
vi) Include copies of your two lesson plans. The lesson plans do not count towards the total minimum word count for the paper and should be placed in the appendix of your paper.
vii) Submit the assignment to the instructor in ANGEL by the end of Module 6.
viii) Additionally, submit the assignment in TaskStream. Directions for submitting to TaskStream can be found on the College of Education’s page in the Student Success Center.
P 5–6: Metal Press
Your firm uses return on assets (ROA) to evaluate investment centers and is considering changing the valuation basis of assets from historical cost to current value. When the historical cost of the asset is updated, a price index is used to approximate replacement value. For example, a metal fabrication press, which bends and shapes metal, was bought seven years ago for $522,000. The company will add 19 percent to this cost, representing the change in the wholesale price index over the seven years. This new, higher cost figure is depreciated using the straight-line method over the same 12-year assumed life (no salvage value).
a. Calculate depreciation expense and book value of the metal press under both historical cost and price-level-adjusted historical cost.
b. In general, what is the effect on ROA of changing valuation bases from historical cost to current values?
c. The manager of the investment center with the metal press is considering replacing it because it is becoming obsolete. Will the manager’s incentives to replace the metal press change if the firm shifts from historical cost valuation to the proposed price-level adjusted historical cost valuation?
P 5–15: U.S. Pump Systems
U.S. Pump is a multidivisional firm that manufactures and installs chemical piping and pump systems. The valve division makes a single standardized valve. The valve division and the installation division are currently involved in a transfer pricing dispute. Last year, half of the valve division’s output was sold to the installation division for $40 and the remaining half was sold to outsiders for $60. The existing transfer price has been set at $40 per pump through a process of negotiation between the two divisions, with the involvement of senior management. The installation division has received a bid from an outside valve manufacturer to supply it with an equivalent valve for $35 each.
The manager of the valve division has argued that if it is forced to meet the external price of $35, it will lose money on selling internally. The operating data for last year for the valve division are as follows:
Analyze the situation and recommend a course of action. What should installation divis ion managers do? What should valve division managers do? What should U.S. Pump’s senior managers do?
