OSI model stands for Open System Interconnection It is a framework that guides the applications on how they can communicate in a network.
OSI model has seven layers. They are listed below,
Physical Layer: Deals with transmission and reception of unstructured data through a physical medium.
Data Link Layer: Helps in transferring error-free data frames between nodes.
Network Layer: Decides the physical path that should be taken by the data as per the network conditions.
Transport Layer: Ensures that the messages are delivered in sequence and without any loss or duplication.
Session Layer: Helps in establishing a session between processes of different stations.
Presentation Layer: Formats the data as per the need and presents the same to the Application layer.
Application Layer: Serves as the mediator between Users and processes of applications.
