Assignment Brief and Guidance: Assignment scenario (cont.) The CEO Mr. Nguyen is happy with your first report and now he has asked you to analyse the specification from the institution, as given earlier. You need to design and implement the networking project within a given timeframe: Task 2 Design efficient networked systems:
The purpose of this assignment is: •Design an efficient network system

4. Discuss and explain the USER Requirement for the design Any project, but particularly those involving computer systems, needs a solid list of user requirements to be successful. Because they do not accurately explain what the system should perform, here is where many projects fall flat. In reality, many systems have just been allocated a delivery date, a spending limit, and an ill-defined task. The cause of this issue is that: - Business consumers have limited knowledge of what a computer system could do for them; - Computer system developers rarely have as good an understanding of how a business operates and should operate. As a result paralysis sets in and business management time is concentrated on meeting timescales and budgets, rather than what is going to be delivered.

5. Provide a logical design of the network base on user requirement Figure 3 – Logical Network Design The above design article uses 3 routers to connect with 3 rooms, including Lab Student Computer room, Lab Staff Computer room and server room. The problem requires the student room to have 50 computers, so the design should use the PT switch. Each of these switches can connect up to 24 computers, so we will install 3 switches for the student room. Similar to the Lab Student Computer Lab, the Lab Staff Computer room is required to set up 35 computers and 3 printers. We will also install with 3 type PT switches in this room. 2 switches serve the needs of connecting to 35 computers and the other switch will be used to set up the printers. Server room will have 1 switch to connect to the servers and also be used PT switch type to satisfy requirements and comfort for future expansion intentions. The above design is used to use the network with star topology because this network is such that running the program at the fastest speed and when the network cable is broken will lose the connection of one machine, and the others will still works normally. Especially, this type of network can be expanded according to the needs of the user.

Task 2 - Evaluate the design to meet the requirements
1. Provide test plan No Test Plan Purpose 1 Ping two computers on the same LAN Check the signal of computers on the same network 2 Ping two computers on different LAN Check the signal of computers on different network 3 Ping computer to printer on the same LAN Check the signal of computers and devices on the same network 4 Ping computer to printer on different LAN Check the signal of computers and devices on different network 5 Ping between server and computer Check if the signal of the computer is connected to the server or not 6 Ping between computer to DNS service Check the signal of computers on the same network
2. Evaluate the design of the network Three rooms are located on three distinct floors according to the design depicted in P5. The first room is the computer lab for students, the second is the computer lab for staff, and the third is the server room. The staff room contains 35 computers and 3 printers, the student room has 50 computers, and the other room is set up with servers and printers at the same time to address the issue. With the P5's design, more computers can be added in the future. One switch may link to 24 computers in the student lab's computer lab, which employs three similar switches. One student room can hold up to 72 computers in total. The student computer lab can accommodate present requirements and grow in the future. Only 50 computers are currently in the student room; therefore, 22 more computers may be added in the future. Based on its architecture, the Staff Lab is similarly set up with three switches like the Student Lab. But only 35 PCs and 3 printers were initially installed in the space. Therefore, it will be feasible to grow and link to 34 more machines in the future. **Task 3 - Implement a networked system based on a prepared design
