Multiréteg

Multiréteg is a term that can refer to several different concepts depending on the context. In a general sense, it means "multilayer" or "multi-layered."

In the field of computer networking, multiréteg often refers to a system or model that operates at multiple layers of the OSI or TCP/IP model. This means that different functionalities are handled by distinct layers, each with its own set of protocols and responsibilities. For example, the internet's architecture is inherently multiréteg, with layers for physical transmission, data framing, network routing, transport control, and application services.

In materials science and engineering, multiréteg describes a structure composed of multiple distinct layers stacked together. This could include things like laminated materials, composite structures, or coatings applied in successive stages. The properties of a multiréteg material are often a combination of the properties of its individual layers, or they can arise from the interactions between the layers. Examples include multilayer films for packaging, protective coatings on surfaces, or printed circuit boards with multiple conductive and insulating layers.

The specific meaning of multiréteg is thus derived from the field in which it is used, but the core idea remains the presence and interaction of multiple distinct layers.
