Logical design in networking emphasizes the interaction and communication between various network components, independent of specific physical devices It encompasses the overall network structure, including the IP addressing scheme, routing protocols, network services, quality of service (QoS) policies, security measures, and network address translation (NAT) policies This design serves as the foundation for the physical implementation of the network, facilitating easier deployment and management of network elements.

1% %° The features of logical design in networking are: 1%
- Abstraction: Focuses on high-level representation
- Topology Definition: Determines network structure
- IP Addressing Plan: Designs IP address scheme
- Routing Configuration: Selects routing protocols
- VLANs: Creates logical network segments
- Network Services: Identifies essential services
- QoS: Prioritizes traffic for better performance
- Security: Implements access controls and encryption
- NAT: Manages private-to-public IP translation
Physical design in networking translates the abstract logical design into tangible hardware and components This process includes selecting networking devices, planning cable layouts, determining device placements and power needs, organizing equipment in racks, and ensuring physical security Additionally, it encompasses conducting tests and creating a diagram that visually represents the network's physical structure.

‘BTEC 3 m1 ‘BT E Cc ô+ 1% Because physical network diagrams depict the entire topology of the physical network, they can include a number of different components:
Connections play a crucial role in a physical network diagram, as they represent the cabling that links various devices within the network To convey different types of connections, such as fiber and copper, you can utilize various colors, line thicknesses, and styles, depending on the level of detail needed.
Labels are essential for guiding viewers in understanding diagrams that utilize generic icons It is important to label all active and managed network components with their respective hostnames and IP addresses.
In network management, it is essential to label devices such as switches, routers, and firewalls clearly Active devices that are managed remotely should be distinctly marked, possibly using a different font, to differentiate them from other network components.
- Diagram Legend: a diagram’s legends tells the viewer what the different objects and connec- tions mean The different graphics, icons, colors, and gives it real-world meaning
- Switch Stacks: switch stacks, that function similar to a chassis switch, are generally depicted as a single object/device

1.1.3 Compare Logical Design and Physical Design
The distinction between logical design and physical design in a network lies in their presentation Logical design is conceptual and abstract, focusing on the relationships among objects, while physical design emphasizes the efficient storage and retrieval of these objects.

1.2 Discuss and explain the USER Requirement for the design
- User requirements is the set of requirements gathered or derived from user input and is what is needed by users to successfully accomplish their tasks on the system
The system must be adaptable to users and their environments, ensuring quick and reliable access to information while delivering high-quality service These aspects highlight the essential requirements for effective user experience.
