Why do laptops have trackpads?
Show answer & explanation
Answer: It lets you point and click without carrying a separate mouse
It lets you point and click without carrying a separate mouse ✓ — Correct! A trackpad gives you built-in pointing, so you can use the laptop anywhere without packing an extra mouse. It senses your finger's position and supports gestures like two-finger scrolling and pinch-to-zoom. It's less precise than a mouse, which is why gamers and designers often plug one in, but it makes the laptop truly portable.
It keeps your hands from getting tired when you type a lot — Wrong. Using a trackpad can actually add some strain compared with keyboard-only typing, and reducing fatigue isn't the design goal. The main purpose is portability: a built-in pointing device you always have with you.
It draws less power than a mouse so the battery lasts longer — Wrong. A trackpad does use very little power, but that's not why laptops are built with one. The reason is portability: you get a pointing device without needing to carry anything extra.
