So for serial communication, only one wire is used to transfer 8-bit data (bit by bit) whereas parallel communication requires eight wires.

But for parallel communication individual wires are required for each bit. In the case of serial communication, one wire is enough to send multiple bits of data in the form of a stream of bits. Communication protocols generally have some standards to maintain, and these standards are governed by groups or consortiums.Ĭomputers can communicate with one another using serial or parallel transmission of data. It could, in theory, be used to facilitate the implementation of an asynchronous serial protocol, but it itself isn’t one. It’s just an electronic circuit that receives and transmits data serially in an asynchronous manner. Note that UART is NOT a communication protocol like SPI, I2c etc.
