Chapter III DESIGN EFFICIENT NETWORKED SYSTEMS

I Provide a logical/physical design of the networked system with clear

explanation and addressing table (P5)

1 Explain the difference between logical and physical design

® Logic design is an important step in the development of a software system or solution, the main goal of logic design is to create a conceptual representation that accurately captures the nature of the system's function and structure This process includes defining the system's features, determining how its components interact and relate to each other, and establishing a clear

Figure 1 Definition of logic design

understanding of the system's goals and requirements

- Also it is important to focus on the core elements and their interrelationships, while intentionally avoiding specific implementation details, hardware constraints, or software engineering considerations By abstracting these technical aspects, logical design allows a streamlined approach to conceptualizing the system's architecture, making it easier to capture the basic ideas behind the solution

- The ultimate goal of logic design is to create a logical model that serves as a high-level blueprint for the software system This model should accurately represent the intended function and behavior of the system, providing a clear and comprehensive overview of how the different components work together to achieve the desired goals

- Physical design is an important stage in the software development process where the conceptual representation from the logical design phase is transformed into a tangible and actionable form

- With the physical design to the selection of hardware components, software engineering practices and system configurations are carefully considered to ensure that the resulting implementation meets various critical requirements, including performance, scalability, security, and operational

efficiency

Resources: 50 student lab computers, 35 staff computers, Three printers

All computers and printers are located on the third floor, with the exception of the first and second floors of the laboratory, which do not have printers As a Network Engineer, | am responsible for designing and setting up the network infrastructure to ensure seamless connectivity and efficient communication between all devices on the campus This includes configuring network devices, establishing secure connections, and optimizing network performance to meet the specific requirements of the educational institution

2.2 Explain

The scenario involves a three-story school building where a total of 85 computers and three printers are evenly distributed The building has different rooms and departments, each with specific networking needs:

The1st and 2nd floor:

There are three labs on each floor, with a total of 50 computers for student use Each lab has a capacity of 8 to 9 students Labs can be interconnected, allowing data exchange during the learning process

The 3rd floor:

Staff room has 15 computers and a printer, Marketing room has 6 computers and 1 printer, management room has 5 computers and 1 printer, Marketing staff room has 6 computers and 1 printer, Admin room has 3 computers and 3 servers

12

- Asa Network Engineer, responsibility will be to design and implement the network infrastructure

to ensure efficient connectivity, security, and data exchange for all departments and laboratories

in the building

- First and Second floor: The first is a floor consisting of 3 rooms, each room has from 8 to 9 students and it is developed according to the model of a link bus

Figure 4 Logical design of first floor

- The second floor is like a floor, it also develops according to the bus model

Figure 5 Logical design of second floor

- Teacher's room: The room includes 15 computers, a switch and a printer, the computers and printers will be connected to each other by a bus topology

- Manager's Room This room has five computers, a switch and a printer and is deployed with a bus topology
