rétegfogalom

The term "rétegfogalom" is a Hungarian word that translates to "layer concept" or "layered concept." It refers to a way of organizing and understanding systems, information, or processes by dividing them into distinct, sequential layers. Each layer typically has a specific function or purpose and interacts with the layers directly above and below it.

This layered approach is widely used in various fields. In computing, the OSI model and the TCP/IP model are prime examples of rétegfogalom, breaking down network communication into seven and four layers, respectively. Each layer handles a different aspect of data transmission, from physical connections to application-level protocols. Similarly, in software engineering, applications are often built in layers, such as the presentation layer, business logic layer, and data access layer, promoting modularity and maintainability.

The rétegfogalom facilitates complexity management by allowing developers or designers to focus on one layer at a time without needing to understand the intricate details of all other layers. It promotes abstraction, where each layer provides a simplified interface to the functionality of the layers beneath it. This modularity also aids in troubleshooting, as problems can often be isolated to a specific layer. The concept emphasizes that changes within one layer should ideally have minimal impact on other layers, provided the interface remains consistent. This principle is fundamental to the design of many modern, complex systems.
