OSI vs TCP/IP Models

3. TCP/IP Model

Strengths:

Practicality: Directly implemented in the internet, making it relevant for real-world use.

Simplicity: Four layers are easier to understand and apply in practice.

Interoperability: Proven to work across diverse devices and networks (e.g., internet backbone).

Limitations:

Less Detailed: Merging Session/Presentation/Application layers can obscure specific functions.

Limited Teaching Tool: Less granular, making it harder to explain certain concepts (e.g., session management).

5. Use Cases

OSI Model:

Education: Ideal for teaching networking concepts due to its detailed, layered approach.

Protocol Design: Guides developers in creating standardized, interoperable protocols.

Troubleshooting: Helps isolate issues to specific layers (e.g., Layer 3 routing vs. Layer 5 session).

Example: Used in academic settings or when designing new network protocols.
