What does asynchronous mean? In contrast to the synchronous interface, which uses a <strong>handshake<\/strong> for synchronization, this type of interface has a buffer in the form of a queue (FIFO), into which the data can be written and retrieved by the receiver at the appropriate time. <strong>Protocols that implement asynchronous data transmission<\/strong> typically use identifiers such as a start bit (initial or 0-bit). These start bits are optionally followed by a check bit, also known as a parity bit, and at least one stop bit (1-bit). The check bit can be either even or odd. So if the number of 1s in the transmitted byte is even, the check bit must be 0 (for odd) or 1 (for even), otherwise the previous transmission was not correct.
