Information quality is how good information is. It means that it is accurate, up-to-date, and from a reliable source. It's important because if you're using bad information, it can lead to bad decisions. For example, if you're trying to decide what kind of car to buy, you need to make sure that the information you're using is good, such as reviews and ratings from people who have bought the car. If the information is bad, you might make the wrong choice.
