Information refers to the objects transmitted and processed by audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world.
In all communication and control systems, information is a common form of communication. 1948, the mathematician Shannon pointed out in his paper entitled Mathematical Theory of Communication that information is used to eliminate random uncertainty. The most basic unit of creating everything in the universe is information.
