More Nuts and Bolts

There are many kinds of checks and balances in sending communication, and they all mimic how humans convey information between each other. We humans continually acknowledge the fact that we receive a message from somebody by using some kind of a feedback signal. In the case of Morse code, the feedback has to be in terms of the Morse code technology. In the case of digital codes of any kind, whether it is American Standard Code for Information Interchange, ASCII or any other method, the feedback has to be in the terms of that code. This is known as “protocol” Digital communications over a single wire, known as a data highway, have saved in excess of 30 percent of installation costs compared with hardwired connections for the same functions. If the entire sequence of bits can be sent in parallel, the transmission can be very fast. Consequently, most transmission between devices is serial.
