The OSI model is a networking model for understanding and designing a network architecture that would be flexible, robust, and interoperable. Communication between different systems without requiring changes to the logic of the underlying hardware and software is the main purpose of the OSI model.

The ISO-OSI model has a seven-layer design architecture which is as follows:

  • Application Layer - It indicates the Network process to the application.
  • Session Layer - It indicates Interhost communication.
  • Transport Layer - It indicates the end to end communication and reliability.
  • Network Layer - It indicates Path determination and IP or logical addressing.
  • Data Link Layer - indicates MAC and LCC physical addressing.
  • Physical Layer - indicates Media signal and binary transmission.
  • Presentation Layer - It indicates Data representation and encryption
