Fstab

Ok kiddo, fstab stands for "file system table" and it's basically like a secret diary that your computer keeps to remember all the different ways it can access all the storage devices connected to it, such as hard drives or USB sticks.

Think of it like having different drawers in your room where you keep your toys. You need a special key to open each drawer, and your computer needs to know where these drawers are and how to open them. Just like how you remember which drawer has your Legos and which one has your action figures, your computer needs to remember which directory or partition contains certain files or programs.

So, fstab is like your computer's Lego instruction booklet that tells it which key to use and where to find the right drawer for each of its different storage devices. It's important because without it, your computer wouldn't know how to access all the files stored on its different devices.

Whenever you plug in a new USB drive or connect a new hard drive, your computer will use fstab to figure out how to read and write data to those devices. And when you turn your computer on, fstab helps it to automatically mount all the different storage devices it's connected to, so you can start using them right away.

So, in short, fstab is like a map that helps your computer find and organize all the different storage devices connected to it so you can use them easily.
