Serial communication
Typically, serial communication in computer science and telecommunications is a type of communication where data is sent one bit at a time over a communication bus.
Nowadays, we can see serial communication all around us, and often we don't even realize this. J The "S" in the USB acronym means Serial (USB is Universal Serial Bus), and represents the underlying serial communication bus used by every higher protocol.
Let's dig into that right now.
Serial and parallel communication
Serial communication is often defined by its opposite form of communication, parallel communication, where several bits of data are sent out over a link made by several parallel channels at the same time. Look at the following figure:
Basic, unidirectional serial communication between a speaker and a listener
Now let's compare this to a parallel case:
Basic, unidirectional parallel communication between a speaker and a listener
In these two figures, a speaker is sending the following data byte: 0 1...
