Table 1: Addressing Table.............................................................................................................................................. 9 Table 2: test plan ......................................................................................................................................................... 10 Introduction In the paper that came before, the theory and definition of the gadgets that would be produced in any given lab were given. The previous report received high marks from the corporation, therefore this one will go into more depth on how the institution looked into the criteria. The system will be fully developed with all necessary hardware.according to the subject, between floors, and seamlessly related to one another. Additionally, readers will be able to comprehend the IP table adequately thanks to a clearer description of the physical and logical architecture in the report. Examine test results, make a statement, and test the system. Identify the benefits and drawbacks of the system. and will place more emphasis on the flaws in this system. Examine this report as well. P5 Provide a logical/physical design of the networked system with clear explanation and addressing table
1. The difference between logical and physical design
Logical network design : Connections and interactions between network devices are described in logic diagrams. Relationships describe how devices connect to each other, how they collaborate to provide network services and support, and respond to user requests. (McCabe, 2007). Figure 1 :Physical Topology
3 printers in terms of volume requirements. In order to meet the needs of the machines, a File Server will also be added to the system. Regarding connectivity, the machines in this system must be able to connect to anywhere in the network to easily exchange data and manage the system. About the design, build 35 staff computers on the 1st floor, on the 2nd and 3rd floors are two labs for students, the design must have a clear location, the design is optimal and simple because of the purpose of use. For educational purposes only, the clearer the physical design, the easier it is to install. A reasonable proposal for equipment for this network is 4 switches and 2 routers, these 2 routers connect directly to each other. 1 router acts as a dhcp server to give dynamic ip addresses to all 4 switches and connect directly to 2 switches, one router configures ip helper and connects directly to the other 2 switches. Each lab connects to a switch, the admin and manager rooms connect to a switch, and the teacher and marketing rooms connect to a switch. In terms of latency, low latency is the desire of every network system, the transmission speed must be as fast as possible for employees to work most effectively. In terms of cost, this is a simple network system, so the cost should not be too great, the equipment should be considered for optimal price but must not affect the long-term performance of the network. In addition, in the future, new machines may be added to the network, so the number of ports must be left over. Therefore, the 2 switches used in the staff room are 24 ports (their prices are cheap), the 2 lab switches are 48 ports (due to future development). Using multiple switches is due to the convenience of installation and the floors do not depend on each other. Finally, security is necessary to protect the information of employees, students and data in the network.
3. provide a logical design of the network based on the specific requirements of the user
Requirements are 50 PC-student, 25 PC-Staff, 3 Printers, 1 File server. Due to the large number of devices, the number on the logical design is representative only. The design has 3 floors and 6 rooms, including 2 routers and 4 switches.

Ping from PC at Lab 2 room to all rooms Ping each device (PC or Printer) in the Admin, marketing, Manager, Teacher, lab 1 rooms using PClab 2. Table 2 : test plan
2. Showing the pros and cons of design based on user requirements
Pros: This is a kind of star model, it is very simple and has few problems, if one device has a problem, it will not affect the whole network, the network speed is fast because all devices can connect to each other in the fastest way, ensuring that no connection is isolated, in the future can add or remove terminals easily. Security is also very high. Using a dynamic IP allocation system, there is no time to manually enter IP, convenient for the connection of computers and devices in the network. Cons: In terms of cost, even if it saves a bit, the cost of these devices is high, not to mention the long cable transmission leads to increased costs. There is no wifi network between floors, a bit disadvantageous if students or teachers, admins, managers, and marketing staff bring laptops or phones to the company. Solution: Set rights to limit access to certain rooms. For instance, only administrative computers are permitted to ping all networked rooms, and computers in labs 1 and 2 are not permitted to ping staff computers on floor 1. By including wireless devices to the network, the network's usable area can be expanded. Add HTTP, DNS, and email servers.
