翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Synchronous serial communication ： ウィキペディア英語版 Synchronous serial communication Synchronous serial communication describes a serial communication protocol in which "data is sent in a continuous stream at a constant rate." Synchronous communication requires that the clocks in the transmitting and receiving devices are ''synchronized'' – running at the same rate – so the receiver can sample the signal at the same time intervals used by the transmitter. No start or stop bits are required. For this reason "synchronous communication permits more information to be passed over a circuit per unit time" than asynchronous serial communication. Over time the transmitting and receiving clocks will tend to drift apart, requiring ''resynchronization''. ==Byte-oriented protocols== Early synchronous protocols were byte-oriented protocols, where synchronization was maintained by transmitting a sequence of synchronous idle characters when the line was not actively transmitting data or transparently within a long transmission block. A certain number of idles were sent prior to each transmission. The IBM ''Binary Synchronous protocol'' (Bisync) is still in use, Other examples of byte-oriented protocols are IBM's ''Synchronous transmit-receive'' (STR), and ''Digital Data Communications Message Protocol'' (DDCMP) from Digital Equipment Corporation. Other computer manufacturers often offered similar protocols, differing mainly in small details. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Synchronous serial communication」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
