The Open System Interconnection (OSI) model defines a networking framework to implement protocol in seven layers.

 

7)      Application Layer                         Data Generation

6)      Presentation Layer                       Encryption and Formatting

5)      Session Layer                              Establish Connection

4)      Transport Layer                           Delivery and Sequencing

3)      Network Layer                             Routing to Destination

2)      Data Link Layer                           Local Network Host Delivery

1)      Physical Layer                             Access to Media

 

Application Layer: - This layer provides application services for file transfers, Email, and other network software services.

Presentation Layer: - This layer used to present data to the application layer in an accurate well-defined and standardized format.

Session Layer: -  This layer establishes, manages and terminates connections between applications.

Transport Layer: - This layer provides reliable communication between two hosts.

Network Layer: - This layer provides data routing paths for network communication.

Data Link Layer: - This layer provides access to media with MAC address and handling error notification network topology & flow control.

Physical Layer: - This layer provides concept of half-duplex or full duplex and moves bits between devices.
