Serial and parallel communication
Now that we have a basic understanding of some of the electronic components, let's move into the different kinds of communication mediums that are used in embedded devices.
The two methods of data communication in embedded devices are serial and parallel communication. As the name suggests, serial communication sends data one bit at a time sequentially. This means that if 8 bits have to be transferred, it will send one bit after the other, and the data transfer will be complete only when all the 8 bits are received.
However, in cases of parallel communication, multiple bits would be transferred at the same time, thus making the data transfer process faster compared to its serial counterpart.
