Executable space protection

Okay, so let's say you have a toy box and all your toys are in there. You can play with your toys and it's safe because they are in the toy box. Now imagine if you had a toy that was actually dangerous, like a sharp toy or a toy that could explode. You wouldn't want to play with that toy, right?

The same thing happens with your computer. Your computer has a place where it keeps all of its programs and data called memory. Just like your toy box, memory can be safe or dangerous. Dangerous things in memory are called malware, which is like a bad toy.

Executable space protection is like having a security guard for your memory. Whenever a program asks to use some memory, the security guard checks to make sure that the program isn't trying to access dangerous memory that it shouldn't have access to. If the program is trying to access dangerous memory, the security guard stops it from doing so.

This is important because if a bad program or virus tries to sneak into your computer and do bad things, the security guard can stop it before it causes any harm. That way, your computer can stay safe just like your toy box.
