Input/output

Input and output are things that happen when you use a computer. Input is what you put into the computer, like when you type on the keyboard or move the mouse. Output is what the computer gives back to you, like when you see something on the screen or hear a sound from the speakers.

Think of it like playing with toys. When you play with blocks, you put the blocks together and build something new. That's like putting input into the computer. Then, when you're done building, you can show it to your friends and they can see and play with it too. That's like getting output from the computer.

And just like when you play with toys, sometimes things don't work quite right with input and output on the computer. Sometimes the computer doesn't understand what you're trying to do, and sometimes it doesn't give you back what you expect. So, it's important to learn how to use input and output properly so you can play with the computer in the best way possible.
