interfaced

Interfaced is the past tense and past participle of interface, used as a verb meaning to connect or interact with another system, component, or device through a defined interface. It can describe the act of establishing a point of contact that enables communication, data exchange, or coordination between otherwise separate elements. In informal use, it may also function as an adjective to describe components that have been connected by an interface, though this use is less common.

In computing and electronics, interfacing is a core concept for achieving interoperability. It covers software-to-software connections via APIs, data formats, and communication protocols, as well as hardware connections through physical ports, buses, and standardized interfaces. When systems are interfaced, they typically require data mapping, protocol alignment, timing considerations, and error handling to ensure reliable interaction. The goal is to enable seamless transfer of information and coordinated behavior without exposing internal implementations.

Common examples include a software program interfacing with a database, a sensor interfacing with a microcontroller, or a user interface interfacing with an application programming interface. Technologies and practices such as middleware, adapters, drivers, and wrappers are often used to facilitate interfacing. The concept is central to interoperability, integration projects, and the design of modular, scalable systems across computing, networking, and embedded environments.
