Clicking, dragging, and scrolling help navigate the user interface. Available in optical, laser, wired, wireless, and even ergonomic designs. 3. Touchpad Commonly found on laptops. Replaces the need for an external mouse. Responds to finger gestures for scrolling, zooming, and clicking. 4. Microphone Converts sound into digital signals. Used for voice commands, video conferencing, gaming, and audio recording. Also plays a key role in voice recognition software. 5. Scanner Converts physical documents or images into digital format. Useful in offices, schools, and art/design work. 6. Webcam Captures video and images for video calls, streaming, and security systems. Some modern webcams also include microphones for sound input. 7. Game Controller/Joystick Designed for gaming. Allows input through buttons, triggers, and analog sticks. Offers precise control and immersive gameplay. 8.
