Why do laptops have trackpads?
Show answer & explanation
Answer: Portability without external mouse
Portability without external mouse ✓ — Correct! Trackpads (touchpads) provide built-in pointing without external mouse—important for portability. You can use laptop anywhere without carrying extra peripherals. Technology: capacitive sensing detects finger position, gestures (two-finger scroll, pinch-zoom). Trade-offs: less precise than mouse, learning curve. Gaming/precision work often prefers external mouse. Trackpads make laptops truly portable!
Save battery power — Wrong. Trackpads don't save battery significantly. Their purpose is portability—built-in pointing without needing an external mouse.
Prevent hand fatigue — Wrong. Trackpads can reduce fatigue from keyboard-only use, but primary purpose is portability—built-in pointing device.
