A cross-cutting technological dimension has to do with the granularity of the units that are transmitted by the CMC system, that is, whether the transmission is message-by-message, or character-by-character (a third possibility is line-by-line transmission). This has implications for whether or not simultaneous feedback is available during message exchange. With message-by-message transmission, the receiver does not typically have any indication that the sender is composing a message until it is sent and received; thus, it is impossible for the receiver to interrupt or otherwise engage simultaneously with the sender’s message. Cherny (1999) terms this transmission “one-way”; most CMC systems in current use make use of one-way transmission.
