TV with antenna and modern tv side by side

A key part of the essence can be encapsulated in the idea of digital vs. analog. Digital information is presented in a discrete format, meaning that there are defined values. Analog information is presented in a continuous format, meaning that there are an infinite number of values and no defined values. The transition from analog to digital can be seen in typical items such as TVs. As TVs advanced into their digital era we saw that the ability to separate the noise from the signal became much easier. The key differentiating factor between digital and analog is that with digital the signal can be preserved while getting rid of the noise. This change occurred throughout the United States. In 2009, the Federal Communications Commission ended up mandating that all United States Tv signals must use digital transmission. This change is what allowed channels to flow more simultaneously. Less static and fuzz was seen with digital signals.  

Digital doesn’t apply to only technological things. An example of something digital that everyone has is the genome. There are a discrete number of bases that are used to makeup the genome; A, T, G, C. It is amazing that something so prevalent in the world can be considered digital even when most people would think of technology.
