OSI vs TCP/IP Models

1.1. Comparison of OSI and TCP/IP Models

1. Structural Differences

OSI Model:

Layers: Seven layers (Physical, Data Link, Network, Transport, Session, Presentation, Application).

Nature: Theoretical framework, designed to standardize and teach networking concepts.

Granularity: Highly detailed, with distinct layers for specific functions (e.g., Session and Presentation layers separate from Application).

Development: Created by ISO as a universal reference, not tied to a specific protocol suite.
