The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network. The OSI model is divided into seven distinct layers, each with specific responsibilities, ranging from physical hardware connections to high-level application interactions. Each la...

The OSI model includes seven distinct layers. The application layer (layer 7), the presentation layer (layer 6) and the session layer (layer 5) comprise the software layers of an OSI, where all transmissions to and from software apps (including operating systems and utilities, such as web br...
the OSI Model describes the transmission path that data takes from the end-user level (layer 7: Application Layer) to the physical transmission of bits across communication links and network cards (layer 1: Physical Layer) and all layers in between. ...

This tutorial explains the OSI reference model. Learn the seven layers of the OSI model and the functions of each layer in detail through examples.
An application running on your computer can communicate with other layers in the OSI model, but the interface runs on the application layer. For example, anemail clientyou use to send messages runs on layer 7. When a message arrives at the destinationhost, this layer then presents it to the...
