Definition
The Open System Interconnection Model (OSI) is standard developed by the networking industry with seven-layer model for network protocol architecture:
- Physical Layer: Converting data into a stream of electric or analog pulses that cross a transmission medium
- Data Link Layer: Provide an interface with a network adapter; maintain logical links for the subnet.
- Network Layer: Support logical addressing and routing.
- Transport Layer: Provide error control and flow control for the network.
- Session Layer: Establish sessions between communicating applications running on the communicating computers.
- Presentation Layer: Translate data to standard formats; manage encryption and data compression.
- Application Layer: Provide a network interface for applications; support network applications for file transfer and communications
