Which of the following are examples of pointing devices?

Pointing devices are input devices that allow users to interact with a computer's graphical user interface by pointing, selecting, and manipulating objects on the screen. The correct answer identifies examples of these devices accurately.

The mouse is a classic pointing device that enables users to move a cursor around the screen, click on icons, and perform other actions based on its movements relative to a surface. The touchpad, commonly found on laptops, serves a similar purpose by detecting finger movements and gestures to control the cursor on the screen. Both the mouse and touchpad facilitate direct interaction with the computer interface, making them quintessential examples of pointing devices.

In contrast, options that include the keyboard, scanner, and microphone do not fit into the category of pointing devices. The keyboard is primarily an input device for text and commands, while scanners and microphones serve different functions, such as inputting images and audio, respectively. Choosing only the mouse and touchpad reflects the specific function of pointing devices and their crucial role in user interaction with computers.
