What are the main differences between using a drill and a screwdriver for various tasks?

The main differences between using a drill and a screwdriver for tasks are speed and efficiency. A drill is faster and more powerful, making it ideal for drilling holes and driving screws quickly. A screwdriver is slower but offers more control, making it better for delicate or precise tasks. Additionally, a drill can be used for a wider range of tasks, while a screwdriver is limited to driving screws.
