Touchpad

A touchpad is a flat surface on a computer that you touch with your finger instead of using a mouse. It's like a tiny computer screen that you can control by moving your finger across it.

When you move your finger on the touchpad, it sends signals to the computer which tell it what to do. The touchpad has little sensors underneath it that can detect your finger's movements, and these sensors convert them into commands for the computer to follow.

The touchpad also has buttons which are usually located either on the bottom or on the sides. These buttons work like the left and right buttons on a mouse and are used to click and select things on the computer screen.

Overall, a touchpad is a handy tool that can help you navigate around your computer screen without needing to use a separate mouse.
