The OSI (Open Systems Interconnection) seven-layer model and the TCP/IP (Transmission Control Protocol/Internet Protocol) model are two different frameworks used to describe and standardize how data is transmitted over a network.

The OSI model consists of seven layers, each of which represents a specific aspect of the data transmission process:

  1. Physical
  2. Data Link
  3. Network
  4. Transport
  5. Session
  6. Presentation
  7. Application

The TCP/IP model, on the other hand, has four layers:

  1. Application
  2. Transport
  3. Internet
  4. Link

The main difference between the two models is in the number of layers and their definitions. The OSI model provides a more detailed and nuanced view of the data transmission process, while the TCP/IP model is more focused on the practical aspects of data transmission and networking.

Additionally, the TCP/IP model is widely used in the Internet and has become the de facto standard for network communication, while the OSI model is mainly used as a reference framework for teaching and understanding the basics of network communication.
