1. Introduction
The company is in the process of acquiring a new building in Swindon to expand UK operations. The traditional Swindon area is a heavy industry town and there is a serious shortage of qualified staff to design and develop the infrastructure for the new building. The operations manager in the USA has asked to demonstrate understanding the principles and technical skills required to do this. Given that this paper will summarize key concepts of design and implementation of LAN network along with showing the application in light of Packet Tracer Designing and configuring a computer network is a complex process that requires a good understanding of the principals involved. A well-designed computer network is important because it will be more efficient and reliable (Goni, 2021; Qin et al. , 2021; Rasmila and Laksana, 2019). A well-designed network will be better able to meet the needs of the users, and will be less likely to experience problems ( Building A Cisco Wireless LAN , 2002; Chowdhury, 2000). The main components of a computer network are the cables and connectors that are used to connect the different devices. There are a variety of different types of cables and connectors, and it is important to select the right ones for the job. Fiber optics is a type of cable that is used in computer networking. It has a number of advantages over traditional copper cables, including higher bandwidth and immunity to interference. The different types of hardware that are used in computer networking include switches, routers and firewalls. These devices are used to connect the different components of the network, and to provide security and protection. The different components of a computer network are interconnected by a variety of different cables and connectors. The devices are usually configured using a software program, and the configuration can be changed as needed. Testing and debugging a computer network is important because it allows the network to be checked for problems and corrected. Without testing and debugging, the network may not work properly and could cause problems for the users.
2.2 Methodological step of network design
The network design must be able to support up to 100 users(Qiang, 2022). Methodological stage of design of LAN (Local Area Network) are illustrated below:
- The first step in designing a LAN for the company is to identify the devices that will be connected to the network. In this case, the devices include computers, printers, and scanners(Tarkaa et al. , 2017).
- The next step is to identify the type of network that will be used. A LAN is a good choice for a business because it is confined to a certain area and allows devices to share resources(Estepa et al. , 2011). Figure 2 Methodological steps of LAN Network design
- The next step is to identify the network's topology. A bus topology is a good choice for a business because it is easy to set up and is less expensive than other types of networks(Lee and Wu, 1994).
- The next step is to identify the network's speed. A fast network is important for a business because it allows employees to access the network quickly and share resources efficiently(Seneviratne and de Silva, 2021).
- The last step is to identify the network's security features. A LAN should be secured with a firewall and password protection to prevent unauthorized access(Bahri and Chamberland, 2005).

2.3 Networking Tools, and Technique and justification
2.3.1 Devices: Computer, Printers, and Scanner
Devices that include computers, printers, and scanners are important in order to connect and share resources in a network. In general, these devices are important in order to connect to the internet and share files(Seneviratne and de Silva, 2021). In addition, these devices are often used in order to communicate with others in a business setting(Bahri and Chamberland, 2005).
2.3.2 Network: LAN (Local Area Network)
A LAN, or local area network, is a computer network that connects devices within a limited area(Bahri and Chamberland, 2005). LANs are commonly used in homes and businesses to share resources like printers and scanners. LANs are typically faster and more secure than wide area networks, or WANs (Haas and McLaughlin, 2008). WANs connect devices over a large area, like a city or country. LANs are typically connected through a bus topology, which means that all devices are connected to a single cable. This makes setup and maintenance simpler than other network topologies. LANs are often secured with firewalls and passwords, which help to protect against unauthorized access(Chen et al. , 2012). Overall, LANs are a convenient and secure way to connect devices within a limited area.

2.3.5 Security: firewall, password protection
A firewall is a security system that is used to protect a computer or network from unauthorized access. A firewall can be used to protect a computer or network from a variety of threats, including hackers, viruses, and malware(Rasmila and Laksana, 2019). A firewall typically consists of two components: a software firewall and a hardware firewall. A software firewall is a program that is installed on a computer and that provides protection against unauthorized access. Figure 5 Firewall protection A hardware firewall is a device that is installed on a network and that provides protection against unauthorized access. Firewalls can be used to protect a computer or network in a variety of ways(Goni, 2021). One way that firewalls can be used to protect a computer or network is by blocking unauthorized access. Firewalls can also be used to protect a computer or network from a variety of threats, including hackers, viruses, and malware(Qin et al. , 2021).
2.3.6 Hypertext Transfer Protocol (HTTP)
HTTP is a protocol used to transfer data between a client and a server. It is the foundation of data communication for the World Wide Web. HTTP can be used in Lan network design and test to transfer data between devices on the network. This can be used to test the performance of the network and to troubleshoot any issues that may occur.
2.4.2 Configure the new router with the IP address 192.168.1.1 and the subnet mask
To configure the new router, open the command prompt and run the following commands: ipconfig /all and route print. This would give us the IP address, the subnet mask, and the default gateway for the router. ( Please see appendix )
2.4.3 Configure the switch with the IP address 192.168.1.254 and the subnet mask
To configure the switch, open the command prompt and run the following commands: ipconfig /all and route print ( Please see appendix )
2.4.4 Connect the computers to the switch.
To connect the computers to the switch, first connect the computers to the switch. Then configure the computers with the IP address 192.168.1.10/24 and the default gateway 192.168.1.254. ( Please see appendix )
2.4.5 Configure the computers with the IP address 192.168.1.10/24 and the default
gateway 192.168.1.254.
( Please see appendix )
4. Implementation
The network administrator would first configure the switches and routers. Then, the DHCP server would be configured. Finally, the computers would be configured(Osman and Shameem, 2021).
4.1 Switches and Routers
The switches and routers would be configured using the following steps:
1. Connect the switches and routers to the power supply. Figure 7 Connect the switches and routers to the power supply 2. Connect the switches and routers to each other.
Figure 8 Connect the switches and routers to each other
3. Connect the computers to the switches. Figure 9 Connect the computers to the switches
5. Test the network. Figure 11 Lan speed test The LAN network can be tested using a variety of methods. One common method is to use a network analyzer. A network analyzer is a tool that can be used to test the performance of a network(Mateus et al. , 2001). It can be used to test things such as the speed of the network and the amount of traffic that the network can handle. The network analyzer would use statistical measures to test the speed of the network and the amount of traffic that the network can handle(Gendron et al. , 2016). This would include things such as the average amount of time it takes for a packet to travel from one end of the network to the other and the percentage of packets that are lost on the network.
4.2 DHCP Server
The DHCP server is a server that is used to assign IP addresses to devices on a network. When a device connects to the network, it will request an IP address from the DHCP server(Marucheck and Sulek, 1987). The DHCP server would then assign an IP address to the device from its pool of IP addresses(Lima et al. , 2017). It would be configured the DHCP server using the following steps:
1. Connect the DHCP server to the power supply. Figure 12 Connect the DHCP server to the power supply
