The Universal Asynchronous Receiver/Transmitter is a component allowing for asynchronous data transfer. Due to its FIFO method, the UART is essential for fast connections.

Chip that controls the serial port in a computer.

Integrated circuit attached to the parallel bus in a computer that conducts serial communications efficiently.

A universal asynchronous receiver/transmitter (usually abbreviated UART and pronounced ) is a type of "asynchronous receiver/transmitter", a piece of computer hardware that translates data between parallel and serial interfaces. Used for serial data telecommunication, a UART converts bytes of data to and from asynchronous start-stop bit streams represented as binary electrical impulses.
