ühilduv

Ühilduv is an Estonian adjective meaning capable of functioning together with something else; compatible. It is used to describe hardware, software, data formats, standards, or systems that can operate in concert without conflicts. The related noun ühilduvus denotes compatibility or interoperability, and both derive from the verb ühilduma (to be compatible).

In information technology and engineering, ühilduv describes hardware or software that conforms to a given standard or can interoperate with another system. Common expressions include ühilduv riistvara (hardware that is compatible), ühilduv tarkvara (software that runs on a platform), and ühilduvus standardiga (compatibility with a standard). The term is also used in data exchange and telecommunications to indicate that components can be connected and used together without major adaptations.

Linguistic notes: ühilduv follows standard Estonian adjective inflection, agreeing with the noun it modifies in number and case. The broader concept, ühilduvus or interoperability, is central in product documentation, technical specifications, and qualification processes, where it is important to specify which systems, formats, or interfaces are ühilduvad. The term is widely employed across IT, electronics, and engineering contexts to describe compatibility and joint operability.
