Dynamic frequency scaling

Dynamic frequency scaling is a technology that helps computers use their energy efficiently. It works by changing the speed of your computer's processor depending on how much power you need to do a certain task. For example, if you're just reading emails, your processor doesn't need to work as hard and can run at a lower speed, using less energy. But if you're playing a video game, it needs to run faster and use more power to get the job done. So your computer can adjust its processor speed depending on what kind of task you're asking it to do. This way, it has enough power to do the work but it doesn't waste energy when it doesn't need it.
