Linux filesystem is a structured collection of files and directories stored on your device that provides an organized way to store data and manage system resources.
Key components of the Linux filesystem include /bin, /boot, /dev, /etc, /home, /lib, /media, /mnt, /opt, /proc, /root, /sbin, /tmp, /usr, and /var.
The root file system is the starting point of the Linux directory structure, containing all the essential files needed for the system to function and boot properly.
The Extended File System (ext) is a file system specifically developed for Linux, with versions including ext1, ext2, ext3, and ext4, each with improved features and capabilities.
