A trackpad, also known as a touchpad, is a flat, touch-sensitive surface used to control the cursor on a computer screen. It allows users to navigate by moving their fingers across the surface, making it a popular alternative to a mouse. Trackpads are commonly found on laptops and some keyboards, providing a compact way to interact with devices. Most trackpads support multi-touch gestures, enabling users to perform various actions like scrolling, zooming, and switching applications with simple finger movements. They are designed to be intuitive and user-friendly, making them accessible for people of all ages and tech-savviness.
