Difference Between TCP/IP and OSI Model

TCP/IP Model	OSI Model
The TCP/IP model stands for Transmission Control Protocol/Internet Protocol model.	The OSI model stands for the Open Systems Interconnection model.
It is a concise and practical networking model widely used in internet and network communication.	It is a conceptual framework that standardizes network communication protocols.
The TCP/IP model has four layers: Network Interface, Internet, Transport, and Application.	The OSI model has seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
The Network Interface layer handles the physical connection and data transmission over the network.	The Physical and Data Link layers handle physical connections, framing, and error detection and correction.
The Internet layer handles the addressing and routing of data packets across different networks.	The Network layer handles the logical addressing and routing of data packets.
The Transport layer provides reliable data delivery and error control using protocols like TCP and UDP.	The Transport layer provides end-to-end communication, segmentation, and reassembly of data.
The Application layer supports various application-level protocols for specific services like HTTP, FTP, and DNS.	The Application layer supports application-specific protocols and interfaces for user applications.
The TCP/IP model is based on actual implementation and practical network protocols used in the real world.	The OSI model is a theoretical framework that provides a common language and reference for networking concepts.
The TCP/IP model is widely adopted in internet communication and networking protocols.	The OSI model is used for educational purposes, protocol design, and understanding network communication principles.
The TCP/IP model’s layers are more loosely defined and can overlap in terms of functionality.	The OSI model’s layers have well-defined and distinct functionalities without overlapping.

TCP/IP model is a practical and widely used networking model with four layers, focusing on real-world implementation and internet protocols.

The OSI model is a conceptual framework with seven layers, providing a standard reference for networking protocols and concepts. Both models serve as valuable tools for understanding and designing network communication, but the TCP/IP model is more commonly used in practice.
