![]() Nothing much has changed over the years except the speed and type of transmission. Adding code to the carrier was termed modulation and unscrambling the code was called demodulation, giving birth to the familiar term modem ( Modulation, Demodulation). This was similar to morse code as it produced a series of tones representing dashes and dots for each letter and symbol. The keystrokes where superimposed onto the carrier using a code developed by Hayes. One of the earliest solutions developed was for teleprinters which used a carrier. Transmitting information and communicating between devices was achieved either using cables, or alternatively via radio signals. Let us travel back to the early days before the existence of the internet. As we look to explain their unique differences it is worth taking a short history lesson. As technology moves forward it is understandable that a degree of confusion exists as in many instances the black boxes supplied by our internet service providers (ISP’s) contain both technologies. These devices remain of paramount importance in our digital world and historically have been regarded as very separate and non-interchangeable, both with a unique purpose.
