What does a pointing stick do?

• A. It connects to the internet
• B. It serves as a mobile device's input method
• C. It moves the pointer by being pushed in various directions
• D. It enhances sound output

Answer: (C)

A pointing stick is a small pointing device commonly found on the keyboards of laptops. It functions by allowing users to move the on-screen pointer by applying pressure in different directions. When the user pushes the stick, it translates that movement into cursor movement on the display. This provides an alternative to using a mouse or touchpad, making it especially useful in compact keyboard layouts where space is limited. The mechanism works based on the pressure applied to the stick—like a joystick—enabling precise control over the pointer's movement without needing a separate device. This feature is particularly beneficial for users who prefer a more tactile and controlled navigation experience. In contrast, other options discuss irrelevant functionalities; for instance, connecting to the internet, being an input method for mobile devices, or enhancing sound output are not associated with the primary function of a pointing stick.
