Study Notes
Input Devices
- Input devices are hardware components allowing users to input data into a computer system. They translate human-readable information into a computer-understandable format.
- Examples include keyboards, mice, touchscreens, scanners, microphones, webcams, and joysticks.
- Keyboards translate keystrokes into digital signals.
- Mice use movement to control a cursor on the screen.
- Touchscreens allow interaction through direct screen touch.
- Scanners convert printed documents to digital images.
- Microphones capture sound for recording and voice commands.
- Webcams capture video images.
- Joysticks are for gaming and applications needing precise control.
- Input devices are optimized for specific tasks like graphic design, text input, or precise mechanical control.
- Input devices vary in data translation methods, ranging from simple keystrokes to complex sensor readings.
Output Devices
- Output devices display computer data in a human-readable format. They translate computer-readable information into forms humans can see, hear, or perceive.
- Examples include monitors, printers, speakers, and projectors.
- Monitors show visual information on a screen using pixels.
- Printers produce hard copies of documents.
- Speakers output audio signals.
- Projectors display images on a larger screen, suitable for presentations.
- Output devices vary in resolution, refresh rate, and output quality.
- Output devices are crucial for interpreting computer results and providing user feedback.
- Display devices use pixels and vary in quality and technology.
