How to Approach OSI Model Questions

• Structure: Define OSI model → List all 7 layers → Explain each layer's functions → Mention protocols → Discuss interactions
• Diagram: Always include a complete diagram showing all layers
• Key Points: Always mention data units at each layer (bits, frames, packets, segments, etc.)
• Examples: Include at least one protocol example for each layer
• Tip: Use the mnemonic "Please Do Not Throw Sausage Pizza Away" for remembering layers from bottom to top (Physical, Data Link, Network, Transport, Session, Presentation, Application)

How to Approach Network Topology Questions

• Structure: Define topology → List main types → Explain selected topologies in detail → Compare advantages/disadvantages → Mention applications
• Diagrams: Always draw clear, labeled diagrams for each topology
• Key Points: Include connection method, central components, fault tolerance aspects
• Comparison: Create mental comparison tables of advantages/disadvantages
• Tip: Always connect topology to real-world examples (e.g., star topology in office networks)

How to Approach Transmission Media Questions

• Structure: Define transmission media → Classify types → Explain selected media in detail → Discuss characteristics → Mention applications
• Details: Include technical specifications (bandwidth, distance limits, etc.)
• Key Points: Always mention signal types, attenuation factors, noise immunity
• Comparison: Compare different media types on cost, installation, performance
• Tip: Connect media types to appropriate network scales (LAN, MAN, WAN)

How to Approach Network Devices Questions

• Structure: Define the device → Explain its function → Mention OSI layer of operation → Discuss capabilities → Compare with similar devices
