rétegátfedést

Rtegátfedést, Hungarian for "layer overlap," is a concept primarily used in the context of computer networking and information systems. It refers to the way different protocols or services function at distinct levels or layers within a hierarchical architecture. Each layer provides services to the layer above it and utilizes the services of the layer below it. The concept of rtegátfedést is fundamental to understanding how complex systems are broken down into manageable, independent components.

In a networking model like the OSI or TCP/IP model, rtegátfedést is evident in the separation of concerns. For instance, the physical layer handles the transmission of raw bits over a medium, while the data link layer adds framing and error detection. The network layer manages logical addressing and routing, and the transport layer provides end-to-end communication services. This layered approach allows for flexibility and modularity, meaning changes or improvements in one layer do not necessarily require modifications in other layers, as long as the interface between them remains consistent.

Similarly, in software architecture, rtegátfedést can describe the relationship between different modules or services. A presentation layer might interact with a business logic layer, which in turn communicates with a data access layer. This clear division of responsibilities, or rtegátfedést, simplifies development, testing, and maintenance by ensuring that each part of the system has a specific function and interacts with others through well-defined interfaces. It is a principle that underpins many modern technological designs.
