Business Case: Airport IT Network Expansion
An airport authority is seeking your expertise to establish a new IT network infrastructure for its operations. Here are the specifics of the given case.
The airport has a central terminal building with various departments and facilities that need to be interconnected through a robust network.
Within the terminal building, there are:
– Four administrative sections, each housing 30 desktop computers.
– Each section requires 10 portable/laptop computers with wireless connectivity (WiFi).
– A network printer is necessary for shared use in each administrative section.
– It’s imperative that all computers within each administrative section have access to the network.
Additionally, there is a Data Room within the terminal building containing:
– Databases for passenger and flight information.
– Databases for employee records.
– A Printer Server to manage printing for LANs.
– Web Server for internal applications.
– Email Server for communication within the organization.
Your role involves designing and illustrating network diagrams to visualize the proposed solutions.
Question 1: (Network Diagram 1) Develop and draw a network diagram depicting the LOCAL AREA NETWORK (LAN) for one administrative section within the terminal building. Focus on detailing the network setup for this specific section.
Question 2: (Network Diagram 2) Develop and draw a network diagram for INTRANET. This network will connect all computers within the central terminal building, enabling them to communicate with each other and access the resources within the Data Room as well.
Question 3: (Network Diagram 3) The airport authority operates branches in three different cities: DC, NYC, and MIAMI. Design an EXTRANET diagram to establish private communication between all sites. The Extranet should provide access to shared resources while maintaining security protocols.
Question 4:(Network Diagram 4) Update your EXTRANET diagram to include provisions for internet connectivity. This addition will allow all branches and the central terminal to have access to the internet while safeguarding the network’s integrity.
Use https://www.draw.io to develop/draw network diagrams. And place them in your MS Word document.
In your network diagram, write your name on the upper right section of the DRAW.io diagram and export it as JPEG. And insert it into your answer.
And submit the MS Word document

Question 1:
Compare and contrast the basic personal computer system, the typical smartphone system, and the mainframe computer system in terms of their architecture, capabilities, use cases, and impact on modern computing.
Start by providing an overview of each system, including their hardware components, operating systems, and typical specifications.
Explore the primary use cases for each system. How do these systems cater to different computing needs? Are there any overlapping functions or capabilities?
Analyze the architecture of these systems. What are the key design principles and characteristics that make each system unique? How do these architectures contribute to their performance and functionality?
Question 2:
Examine the fundamental interface components in an average computer system, and discuss their roles, significance, and interactions within the system.
Begin by identifying and describing the core interface components typically found in a computer. These may include the central processing unit (CPU), memory (RAM), storage devices (e.g., hard drives or SSDs), input/output devices (e.g., keyboard, mouse, monitor), and expansion slots or ports.
Discuss the specific functions and roles of each component. For example, what is the primary function of the CPU in processing data, and how does it interact with memory and storage devices?
Analyze the connections and data flow between these components. How do data and instructions travel between the CPU, memory, and storage? What is the role of input/output devices in facilitating user interaction with the computer?
Question 3:
Investigate the role of peripherals and the hierarchy of storage in an average computer system, and analyze how these elements contribute to overall system functionality and performance.
Begin by defining what peripherals are in the context of computer systems and providing examples of common input and output devices. Explain how peripherals enhance the user experience and extend the capabilities of a computer.
Explore the concept of the storage hierarchy in computing. Describe the various storage media and devices that make up this hierarchy, from the fastest and most volatile storage to the slowest but highest-capacity options.
