Serial mode is used to transfer data to greater distances and parallel only works for short distances. In serial Communication, only a single wire is required to transfer n bits of data or one or two wires for ready and acknowledge signals whereas in parallel communication, n wires are required to transfer n bits of data. Serial vs Parallel TransferĬomputers transfer data in two ways: serial and parallel. You will also study the use of a communication component – UART (Universal Asynchronous Receiver Transmitter) present within the microcontroller. In this tutorial, you will learn how to serially communicate a PC or any other device with a PIC microcontroller. Unlike parallel communication, where several bits are send at one time, Serial Communication is a process of transmitting data bit by bit.
