Synchronisation between the source and target is required so that the source knows where the new byte begins, since there are no spaces included between the data. The caller could discover completion by some other mechanism discussed later. Machine asynchrone elementaire stator triphase et rotor a cage i t iu iv.

In that case the two units are said to be asynchronous to each other. Synchronous teaching is where the teacher is present at the same time as the learners.
The term synchronous is used to describe a continuous and consistent timed transfer of data blocks synchronous data transmission is a data transfer method in which a continuous stream of data signals is accompanied by timing signals generated by an electronic clock to ensure that the transmitter and the receiver are in step synchronized with one another. In synchronous transmission, data moves in a completely paired approach, in the form of chunks or frames.
