asynchronous communications



  • Communications which are not synchronized by a timing signal. Telephonic communication, in which two or more parties can talk simultaneously, is asynchronous. Otherwise, each person would have to wait a determined time interval before speaking. In computers, asynchronous communication may start or end at any time, with these events being signaled respectively by start and stop bits. This contrasts with synchronous communications, which are synchronized by timing signals. Also called start/stop communications.
