Understanding Data and Information

In computing, data refers to raw facts, figures, and symbols that, when processed, become meaningful information. Information is the collection of patterns and insights extracted from data, allowing users to make informed decisions. For instance, a spreadsheet of temperatures recorded over a month is data, while recognizing a warming trend is information.
