What can you tell us about TCP/IP stack? How is it different than OSI Model.

Question

Accepted Answer

TCP/IP stack is a set of protocols used for communication over the internet, while OSI Model is a conceptual framework for understanding network communication.

TCP/IP stack is a practical implementation of networking protocols used for communication over the internet.
It consists of four layers: Application, Transport, Internet, and Link.
Each layer has its own set of protocols and functions, such as HTTP, TCP, IP, and Ethernet.
OSI Model, on the other hand, is a theoretical framework with seven layers for understanding network communication.
It includes layers like Physical, Data Link, Network, Transport, Session, Presentation, and Application.
The main difference is that TCP/IP stack is widely used in practice, while OSI Model is more of a reference model.
TCP/IP stack is more flexible and adaptable to different network environments, while OSI Model provides a more structured approach to networking.
