/boot: Place files that will be tried at boot, including linux kernel files, boot menu and configuration files required for boot.
/dev: Any devices and interface devices are stored in this directory in the form of files. To access a file is to access a device.
           The more important files are /dev/null, /dev/zero, /dev/tty, /dev/lp*, /devhd*, /dev/sd*, etc.
/etc: Stores the main configuration files of the system. General users can view file attributes, but only root has permission to modify them.
