Characteristics of information
Don't worry, information is indeterminate but there are ways to quantify them. Based on the concept of information, people can summarize that information is characterized by the following The greater the probability of the message occurring Px, the smaller the amount of information, and conversely, the smaller the probability of occurrence, the greater the amount of information. It can be seen that the amount of information we use I to express and the probability of occurrence of the message is the opposite relationship.
When the probability is 1, 100% of the things that happen, everyone on earth knows, so the amount of information is 0. When a message is composed of a number of independent small messages, then the message should be equal to the sum of the information contained in the small messages.
Based on these characteristics, if the mathematical logarithmic function to express, it can be expressed exactly the amount of information and the probability of occurrence of the message between the relationship between the information is not quantified, since the information can be quantified, then it must be given to a unit it, the weight of a person is measured in kilograms, the height of a person is measured in meters, so the amount of information should be measured in terms of what unit it is.
Usually, the amount of information is measured in bits, which is more convenient because the amount of information in a binary waveform is exactly equal to 1 bit.
