FreeBSD jail

A FreeBSD Jail is like a tiny house or apartment that sits on top of a bigger house (your computer). It allows you to separate different parts of your computer (like different apps or websites) from each other. This way, if something goes wrong in one part of your computer (like a virus or hacker attack), it will only affect that one part and not your entire computer. Using jails can make it easier to manage your computer and keep it safe.
