 or application does not require a constant bit rate. Examples are file transfer, email and the World Wide Web. An example of the opposite, a synchronous communication service, is realtime streaming media, for example IP telephony, IP-TV and video conferencing.
Electronically mediated communication
Electronically mediated communication often happens asynchronously in that the participants do not communicate concurrently. Examples include email and bulletin-board systems, where participants send or post messages at different times. The term "asynchronous communication" acquired currency in the field of online learning, where teachers and students often exchange information asynchronously instead of synchronously (that is, simultaneously), as they would in face-to-face or in telephone conversations.

The term asynchronous is usually used to describe communications in which data can be transmitted intermittently rather than in a steady stream.

Email and Internet Chat provide a good example of the difference between synchronous and asynchronous technologies. Email is generally responded to at the discretion of the user and hence is described as asynchronous. However, when in a Chat session each participant knows that the others are waiting for their responses. The resulting "conversations" are synchronous [...]
