What is the difference between digital and analogs?

Answer 1

In chemistry, analog is a compound with a molecular structure closely similar to another.

Analog is also relating to or using signals or info represented by a continuously variable physical quantity such as spatial position or voltage.

Analog is often contrasted (opposite) of DIGITAL --like a clock showing the time represented by "hands" instead of being Displayed DIGITS.

Answer 2

The main difference between analogy and digital signals is that an analogue signal is continuous and a digital signal is discrete. Analog technologies record waveforms as they are, while digital technologies convert analog signals into numbers. Digital communication systems offer much more efficiency, better performance, and much greater flexibility than analog.
