Dynamic Frequency Scaling is a technology used in computer processors to adjust their operating frequency based on current workload demands. By increasing the frequency during high-demand tasks, the processor can perform faster, while reducing the frequency during lighter tasks helps save energy and reduce heat generation. This technique is commonly found in devices like smartphones, laptops, and servers. It allows for a balance between performance and energy efficiency, extending battery life in portable devices and improving overall system stability by preventing overheating.
