📚 Quick Study Guide
🔍 Output devices show us the results of what the computer is doing. They let us see, hear, or even touch information.
💡 Common examples include monitors (to see), printers (to print), and speakers (to hear).
📝 Monitors display images and text. The quality is determined by resolution (e.g., 1920x1080).
🎧 Speakers produce sound. Measured in Hertz (Hz) for frequency and Decibels (dB) for loudness.
🖨️ Printers create hard copies of documents and images.
🎮 Some devices, like touch screens, can be both input and output devices!
🎨 Other output devices are projectors, headphones and plotters.
