A trackpad (or touchpad) and a mouse are tools used to control the cursor on a computer screen and click on things.
A trackpad is a flat, smooth surface usually found on laptops.
You use your finger to move the cursor, tap to click, or swipe to scroll.
A mouse is a small, handheld device often used with desktop computers.
You move the mouse on a surface (like a desk), and the cursor moves on the screen.
It has buttons for clicking and a scroll wheel to move up and down on pages.
Smartphones don’t have a trackpad or mouse because they use a touchscreen for input.
Tap: Touch the screen once to open an app or select an item.
Swipe: Move your finger across the screen to scroll up, down, left, or right.
Pinch and Zoom: Place two fingers on the screen and move them together to zoom out or apart to zoom in.
