What are the different layers of the OSI model?

It is a concept developed by the International Organization for Standardization (ISO) that allows various computer systems to interact via common protocols.

The layers of the OSI model are listed below:

  • Physical Layer: The physical layer allows raw data bits to be sent through physical media.
  • Data Link Layer: The data connection layer is responsible for determining the format of data in the network.
  • Network Layer: The network layer determines the path data will travel.
  • TCP/UDP Transport layer: This layer allows data to be sent via TCP/UDP protocols.
  • Session layer: This layer manages sessions and ports in order to keep the network connected.
  • Presentation layer: Data encryption takes place in this layer, which also guarantees that the data is in a usable/presentable format.
  • Application layer: The user interacts with the application at the application layer.
