ELI5: Explain Like I'm 5

Keyboard protector

A keyboard protector is like a raincoat for your keyboard. It is a special cover that goes over your computer keyboard to keep it safe from all kinds of things that might hurt it like dirt, spills, and even tiny crumbs! Just like how you put on a raincoat so you don't get wet, you put a keyboard protector on your keyboard to keep it dry and clean. That way, your keyboard will stay in good shape and you can type on it for a long time without any problems. It's like magic!
