Network Interface Layer

3.1 OSI Model

OSI stands for Open System Interconnection. The OSI Reference Model focuses on network communications. The model consists of seven layers: uppers layers define functionality while the lower three

layers focus on end-to-end delivery of data. Seven layers from top to bottom:  Application

   

 

Presentation

Session Transport Network

Data link Physical

3.1.1 OSI Layers

The Application Layer provides communication services to applications, consisting of an interface between the network and the application. Examples of interfaces include:  Telnet  HTTP

The Presentation Layer defines data formats and uses encryption and

compression. It supports different protocols for text, data, sound,

graphics, and images, including:  ASCII  EBCDIC

   

MIDI MPEG GIF JPEG

 PICT  TIFF The Session Layer defines processes for establishing, controlling, and terminating communication sessions and provides control and

management of multiple bidirectional messages. The session layer

allows the presentation layer the perception of a seamless stream of

incoming data. Essentially, the layer supports a dialog between the

presentation layers of two or more systems. Session protocols include:
