layered communications and computer network protocol design. It was created as part of the Open Systems Interconnection or OSI initiative. In its most fundamental form‚ it separates network architecture into seven distinct layers: the Application‚ Presentation‚ Session‚ Transport‚ Network‚ Data-Link‚ and Physical Layers. As a result it is frequently referred to as the OSI Seven Layer Model. A layer is a collection of theoretically similar functions that provide services to the layer directly above it and
