See askubuntu.com/q/906581/367990 about the loop devices - they belong to your installed snap applications and are virtual file systems to isolate those. Their storage is backed by your disk. Tmpfs are virtual file systems that reside in your RAM (therefore temporary, as they vanish when you shut down). Their maximum size is half of your RAM by default, but they only occupy the "Used" part, they don't reserve free RAM.

See askubuntu.com/q/906581/367990 about the loop devices - they belong to your installed snap applications and are virtual file systems to isolate those. Their storage is backed by your disk. Tmpfs are virtual file systems that reside in your RAM (therefore temporary, as they vanish when you shut down). Their maximum size is half of your RAM by default, but they only occupy the "Used" part, they don't reserve free RAM.
