Which of the following are pointing devices? (a) Trackball (b) Touchscreen (c) Graphic Tablet (d) Joystick Code:
(a), (b), (c) and (d)
To understand which devices from the list are pointing devices, let's examine each option:
- Trackball: A trackball is an input device used to control the pointer on a computer screen. It is definitely a pointing device, as it allows users to move the cursor by rolling the ball housed in a socket.
- Touchscreen: A touchscreen is a device that allows users to interact with a computer by touching the screen. It serves the dual purpose of a display and input device; hence, it qualifies as a pointing device.
- Graphic Tablet: This is a device used for drawing and design work, where users can control a pointer on the screen using a stylus. It functions as a pointing device, as it helps direct activity on the screen based on user input.
- Joystick: A joystick is an input device used primarily for gaming and simulations, which includes controlling the movement of an object on the screen (such as a pointer or a character). Thus, it is considered a pointing device.
All the devices listed (a) Trackball, (b) Touchscreen, (c) Graphic Tablet, and (d) Joystick function as pointing devices, allowing the user to interact with a computer by affecting the position of the cursor or the elements on the screen.
Therefore, the correct answer is option (a), (b), (c) and (d).
