Duallayer
Duallayer is a descriptive term used across several domains to indicate a system composed of two functional layers. It does not correspond to a single standardized technology, but rather to configurations in fields such as optical storage, coatings and membranes, and computing or engineering architectures where two layers collaborate to perform a task.
In optical media, dual-layer discs contain two data layers on a single side. This arrangement increases storage
In materials science, dual-layer coatings or membranes combine two materials with distinct properties to improve barrier
In computing and engineering, dual-layer or two-layer configurations appear in architectures separating concerns, such as presentation
The meaning of duallayer is context-dependent and should be clarified by the domain and accompanying documentation.
