Information content refers to the amount of meaningful data that is conveyed in a message or signal. It quantifies how much uncertainty is reduced when the information is received. For example, a simple message like "It will rain tomorrow" has high information content if the recipient was unsure about the weather, as it provides a clear prediction. In the context of information theory, information content is often measured in bits. A bit represents the most basic unit of information, indicating a binary choice, such as yes/no or true/false. The more bits required to convey a message, the higher its information content.
