/etc/fstab

The `/etc/fstab` file is a configuration file in Linux systems that tells the operating system which storage devices (like hard drives, SSDs, or USB drives) to automatically connect when the system starts. It specifies how and where these devices should be mounted (accessible) in the file system hierarchy. This helps the system know what storage is available and how to access it without manual intervention each time. Essentially, `/etc/fstab` acts as a blueprint for managing disk connections and their access points during system boot.
