Translation guide
A hardware component that handles both input and output of data, such as a touchscreen, network card, or disk drive. In Japanese, this concept is typically expressed with compound nouns using 入出力 (input/output) or by describing the device's function.
The learner wants to refer to any device that performs both input and output functions, such as in computing or electronics contexts.
Standard technical term for an input-output device. Used in computing and engineering.
This input-output device is fast.
The learner wants to name a particular device that serves as both input and output, like a touchscreen or network interface.
The term 入出力 (にゅうしゅつりょく) can be attached to various nouns to indicate input/output functionality, e.g., 入出力ポート (I/O port), 入出力エラー (I/O error). This is a productive pattern in technical Japanese.
There aren't enough I/O ports.
While 入力出力装置 is understandable, the contracted form 入出力装置 is standard. Using the full form may sound awkward or overly explicit.
Common in IT contexts, using the English abbreviation 'I/O'. Often used in technical documentation and conversation among engineers.
I connected a new I/O device.
Similar to 入出力装置, but 機器 (device/equipment) is slightly broader and can include consumer electronics.
Please check the settings of the input-output device.
Touch panel or touchscreen, a common I/O device. Used in everyday and technical contexts.
This touchscreen is responsive.
Network interface card (NIC), which handles both input and output of data over a network.
The network card broke.
Disk drive (e.g., HDD, SSD) which reads and writes data. Often referred to as ドライブ in casual speech.
I bought an external disk drive.
