noun
start-stop transmission; asynchronous serial communication
Technical computing term for a serial communication method where each character is framed by start and stop bits. Often contrasted with synchronous transmission.
調歩式伝送では、各文字の前後にスタートビットとストップビットが付加される。
In start-stop transmission, start and stop bits are added before and after each character.
Synchronous transmission, where data is sent in a continuous stream without start/stop bits per character, requiring clock synchronization.
Compound of 調歩 (start-stop, literally 'adjust-step') + 式 (style) + 伝送 (transmission). The term 調歩 is a Japanese coinage for the start-stop method in telegraphy and early data communication.
