Which model is used more practically in real-world networking?

Question

Accepted Answer

TCP/IP Model - The TCP/IP model is used more practically in real-world networking. It is the model that the internet and most networks today are based on.

While the OSI model is useful for learning and understanding how networks work, the TCP/IP model is the one that is actually implemented in network devices and systems.

The TCP/IP model is simpler and has fewer layers compared to the OSI model. It groups the functions of networking into 4 main layers.

Main features of the TCP/IP model:

It is used for all internet communications
It is supported by most hardware and software systems
It combines some of the OSI layers into broader layers
It is faster and more practical for real-time use


The TCP/IP model helps computers and devices connect and share data across the internet in a reliable and standardized way.
