interfesz

Interfész, commonly translated as interface, is a boundary or point of interaction between two distinct components through which information, control, or data can be exchanged. In computing and information systems, an interfész defines a contract that specifies how components communicate, what data is exchanged, the format, and the conditions under which interaction occurs. Interfaces enable modularity by allowing parts to be developed, replaced, or evolved independently while preserving compatibility.

There are several kinds of interfészek. User interfaces (UI) govern how humans interact with machines, through graphical, textual, or tactile means. Application programming interfaces (APIs) define methods and data structures that software components use to request services from each other. Hardware interfaces specify physical and electrical characteristics for connecting devices, such as USB or HDMI. Network interfaces enable data transfer between devices over a network, often using standardized protocols.

Design and standards: A well-designed interfész provides a clear contract, stable semantics, and robust error handling. It usually involves versioning, documentation, and attention to backward compatibility. Abstraction levels are chosen to balance ease of use with flexibility, reducing coupling while allowing future extension.

Applications and impact: Interfaces are central to software ecosystems, enabling third-party developers to build on a platform or to connect disparate systems in a network. Examples include RESTful APIs, GraphQL, binary device protocols, and graphical user interfaces.
