Layer
- A layer is “a collection of objects of the same hierarchical rank.”
(ISO/IEC 16500-4:1999, Information technology — Generic digital audio-visual systems — Part 4: Lower-layer protocols and physical interfaces) - A layer is a conceptual or logical division of a system, which is composed of elements. If a system comprises multiple layers, they are typically organized in a hierarchical structure where elements in a layer (N) interact directly only with elements in the adjacent higher layer (N+1) or the adjacent lower layer (N-1) of a system through services provided by each layer.
