Kétirányú

Kétirányú is a Hungarian adjective meaning "two-way" or "bidirectional." It describes systems, channels, or mechanisms that allow movement, transmission, or exchange in two directions. The word is formed from két ("two") and irányú ("directional"), with the suffix -ú creating an attributive adjective.

In everyday language, kétirányú appears in phrases such as kétirányú közlekedés (two-way traffic), kétirányú kommunikáció (bidirectional communication), and kétirányú adatátvitel (two-way data transmission). These uses emphasize that information, vehicles, or signals can travel or be exchanged in both directions, rather than being unidirectional.

In technology and telecommunications, the concept of kétirányú is common in descriptions of bidirectional channels and full-duplex or two-way links, where data can be sent and received across a single connection. It is often contrasted with unidirectional or half-duplex arrangements, which permit transmission in only one direction at a time or in a single direction at any given moment.

The term is widely productive in Hungarian, appearing in many compound nouns to indicate dual-direction capability across various domains, including transportation, networking, and communication technologies. In translation, kétirányú corresponds to the English terms bidirectional or two-way, and in technical contexts it is often paired with more specific descriptors such as kétirányú adatátvitel or kétirányú kommunikáció.
