Business Case For New Horizon Insurance Company Needs Your S

Business Case New Horizon Insurance Company Needs Your Service To Est

New-Horizon Insurance Company needs your service to establish a new IT network. The company has a four-story office building in the city with four offices. Each office will have 25 desktop computers, 10 portable/laptop computers, and require a wireless connection (WiFi). Additionally, there will be one network printer for all employees in each section. All office computers must have access to the network, resulting in four local area networks (LANs) within the building. You need to develop and draw network diagrams, including labeling all network devices and your name and company name on each diagram.

Question 1: Develop and draw a network diagram of a LOCAL AREA NETWORK (LAN) for one office section only, considering just one of the four offices in the building.

Question 2: Draw the block diagram for the INTRANET that connects all LANs in the main building. This intranet should connect all computers across the building to a single database for customer transactions. The diagram should be a simplified LAN diagram representing all LANs, illustrating the backbone network that connects them.

Question 3: Create network diagrams illustrating how all computers in the main building connect to the Internet. Develop three diagrams covering different aspects or components of this connection. Insert these diagrams into an MS Word document, with your name in the upper right corner of each diagram, and export each diagram as JPEG for inclusion.

Follow proper diagramming and documentation guidelines. The total word count for the written explanation should be between 100 and 400 words.

Paper For Above instruction

Establishing a robust and efficient network infrastructure for the New Horizon Insurance Company is essential for seamless operations and data management. This paper details the design process for the local area network (LAN) within one office, the intranet connecting all LANs, and the connection to the Internet, focusing on network architecture, device placement, and connectivity strategies.

Designing the LAN for One Office Section involves creating a network that accommodates 25 desktop computers, 10 laptops, and a shared network printer. The LAN should employ a switched Ethernet topology, utilizing network switches to segment the network into manageable parts, increasing performance and security. Each desktop and laptop will connect to the switch via Ethernet cables, with wireless access points (WAPs) providing WiFi connectivity for portable devices. The network printer should be connected either directly to the network switch or via a dedicated print server. In addition to workstations and printers, network devices such as a firewall, router, and possibly a wireless controller should be included to secure and manage the network.

Creating the Intranet for Connecting All LANs requires a backbone network, which acts as a central hub linking the four LANs across the building. The backbone can use high-speed switches or routers that connect each LAN's primary switch via fiber optic cables to ensure high bandwidth and minimal latency. The intranet's diagram should reflect a hierarchical topology, with each LAN connected to a central backbone switch/router, and all linked to a centralized customer transaction database server. This design enables all computers to communicate efficiently, accessing shared data securely and promptly.

Connecting to the Internet involves integrating the building’s internal network with external networks. A border router provided by an ISP manages this connection, ensuring security via firewalls, and providing the necessary gateway to the global network. The diagrams should depict an external ISP connection linked to a firewall, which then connects to the internal router managing all LAN and intranet traffic. Network security measures such as intrusion detection/prevention systems and VPNs can be included for secure remote access.

In conclusion, designing these layered networks—individual LANs, backbone intranet, and external Internet connection—provides a scalable, secure, and efficient infrastructure for New Horizon Insurance Company. Accurate diagrams and proper device labeling are crucial to visualize and implement this architecture effectively, supporting the company's data needs and growth plans.
