Common in technical documentation for hardware/software compatibility
In technical contexts, '対応' often means 'compatibility' (e.g., '5Gに対応' = '5G compatible'). In general contexts, it means 'response' or 'handling'.
When used as a verb, it's '対応する' (taiō suru), meaning 'to respond to' or 'to handle'.
From Chinese characters '対' (opposite, corresponding) and '応' (to respond)
Can be used as a noun or verb (対応する). The technical meaning of 'compatibility' is a modern extension of the original meaning.
