Lesson 1.0.0. History of Digitalization
The word “digital” or “digit” comes from digitus, the Latin word for finger. Each of the 5 fingers on your hand is unique, yet the 5 fingers work together for one purpose. That explains what digitalisation means.
Digitalisation is a process in which each element of a system is uniquely identified and yet they work together to achieve the goal of the system. Thus, a digital system sends distinctly unique signals, which are referred to as non-continuous signals.
The opposite of Digital is Analog. The analog system sends out continuous signals. For example, in a digital radio broadcast, you can hear the distinctly unique voice of each speaker while in an analog broadcast the individual voices are not that distinct.
