Entropy Measures Uncertainty, Not Just Chaos

Information entropy is not about disorder; it is a mathematical measure of how much surprise or information you gain when you learn an outcome. The more unpredictable an event is, the higher its entropy.

Think of entropy as a scale for how much you really know about a situation before it happens. If a coin is weighted to always land on heads, there is zero entropy because the outcome is certain. However, if the coin is fair, each toss provides maximum information because you cannot predict the result. This concept is the invisible backbone that allows your computer to compress large files into tiny data packets.
