Input and Output Quiz for 2nd Grade Computer Science

📚 Quick Study Guide

• 💡 What is Input? Input is how we tell the computer what to do! It's the information we give to the computer.
• ⌨️ Input Devices: These are the tools we use to give computers input. Think about a keyboard (typing letters), a mouse (clicking things), or a microphone (speaking to the computer).
• 👂 What is Output? Output is what the computer shows or tells us back! It's the result of what the computer did with our input.
• 🖥️ Output Devices: These are the tools computers use to show us output. A monitor or screen (showing pictures/words), speakers (playing sounds), or a printer (printing pictures/words on paper) are great examples.
• 🔄 Think of it like this: You tell a computer to play a song (input), and the computer plays the song through speakers (output)!
