Unsigned code

Unsigned code is software that has not been given a "signature of approval" by the people who made your device or operating system. Imagine if your mom always checks your food before you eat it to make sure it's safe- that's what a signature is like.

When software is unsigned, your device doesn't know if it's safe to run. It's like a stranger approaching you- you don't know if they're a good or bad person until you learn more about them! If you try to run unsigned code, your device might warn you that it could be dangerous, or it might just refuse to run it altogether. This is because unsigned code could potentially be harmful to your device or steal your personal information.

However, sometimes people create unsigned code because they want to do things with their device that the people who made it didn't intend. This is like trying to eat candy before dinner- your mom might say no, but you really want it! Some unsigned code might let you do things like customize your device or add features that weren't there before. But just like with candy, it could also lead to problems if you're not careful.

So in summary, unsigned code is software that hasn't been approved by your device's makers. It might let you do cool things, but it also might be risky and potentially dangerous.
