Which of the following input devices primarily translates physical, real-world movements into digital signals that can be interpreted by a computer system for tasks such as navigation and object manipulation in a graphical environment?​

• A mouse is an input device that translates physical, real-world movements (typically from a hand) into digital signals that the computer system can interpret.

• It is primarily used for tasks such as navigation (moving the pointer on the screen) and object manipulation (clicking, dragging) in a graphical environment (like a desktop interface).

Information Booster:

• The mouse detects movement through sensors (optical or mechanical) and sends the corresponding signals to the computer, allowing for precise control in graphical user interfaces (GUIs).

• It is a pointing device widely used in conjunction with graphical operating systems like Windows and macOS.

Additional Information:

• A. Keyboard: While the keyboard is an input device, it translates keystrokes into digital signals rather than physical movements for tasks like typing and text input.

• B. Microphone: The microphone captures sound waves and converts them into digital audio signals, not related to movement or graphical manipulation.

• D. Scanner: A scanner captures physical images or text (e.g., from paper) and converts them into digital formats but does not interpret real-world movement.
