Input devices are hardware devices that allow users to input data or commands into a computer system. They enable users to interact with the computer and provide instructions or information to be processed. Some common examples of input devices include:
1. Keyboard: A device with a set of keys used to input text, numbers, and commands into a computer.
2. Mouse: A pointing device that allows users to move a cursor on the screen and select or interact with objects.
3. Touchscreen: A display screen that can detect and respond to touch input, allowing users to interact directly with the screen.
4. Scanner: A device that converts physical documents or images into digital format by scanning them.
5. Microphone: A device that converts sound waves into electrical signals, used for inputting audio or voice commands.
6. Webcam: A camera that captures video and audio, allowing users to input live video or participate in video conferencing.
7. Joystick: A handheld device used for controlling the movement or actions of objects in computer games or simulations.
8. Barcode reader: A device that scans barcodes and converts them into digital information, commonly used in retail or inventory management.
On the other hand, output devices are hardware devices that display or present processed data or information to the user. They provide the results of the computer's processing to the user in a perceivable form. Some examples of output devices include:
1. Monitor: A display screen that presents visual output, allowing users to view text, images, videos, and graphical interfaces.
2. Printer: A device that produces hard copies of digital documents or images on paper or other media.
3. Speaker: A device that converts electrical signals into sound waves, used for outputting audio or sound effects.
4. Projector: A device that projects visual output onto a larger screen or surface, commonly used for presentations or movie screenings.
5. Headphones: A pair of audio devices worn over the ears, used for private listening to audio output from a computer or other devices.
6. Plotter: A device that draws or prints vector graphics, commonly used in engineering or architectural applications.
7. Braille display: A device that converts digital text into Braille characters, allowing visually impaired users to read output.
8. Haptic devices: Devices that provide tactile feedback or sensations to the user, such as force feedback joysticks or vibration motors in game controllers.
