Asynchronous communication utilizes a transmitter‚ a receiver and a wire without coordination about the timing of just how long the transmiter leaves the signal at a certain level to represent a single digital bit. Each device uses a clock to mesure out the ’length’ of a bit. The transmitting device simply transmits. The receiving device has to look at the incoming signal and figure out what it is receiving and coordinate and retime its clock to match the incoming signal. Sending data encoded
