Describe the layers of the OSI model?

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 Application layer)
• Application Layer (Serves as the mediator between Users and processes of applications).
