Sometimes, the loop device is erroneously referred to as loopback device, but this term is reserved for a networking device in operating systems. The concept of the loop device is distinct. In BSD-derived systems, such as NetBSD and OpenBSD , the loop device is called "virtual node device" or "vnd", and generally located at /dev/vnd0 , /dev ...
Cryptoloop can create an encrypted file system within a partition or from within a regular file in the regular file system. Once a file is encrypted, it can be moved to another storage device . This is accomplished by making use of a loop device , a pseudo device that enables a normal file to be mounted as if it were a physical device.
Loop device: a similar mechanism, but uses a local file instead of a remote one; DRBD: Distributed Replicated Block Device is a distributed storage system for the Linux platform; ATA over Ethernet: send ATA commands over Ethernet; USB/IP: A protocol that provides network access to USB devices via IP.

The compressed loop device (cloop) is a module for the Linux kernel. It adds support for transparently decompressed, read-only block devices . It is not a compressed file system : cloop is mostly used as a convenient way to compress conventional file systems onto Live CDs .
A loop device is a device that corresponds to a file, usually a disk image. Mounting a loop device allows the file to be accessed as a filesystem. This allows it to be used as a virtual drive. For example, a virtual disk image can be mounted as a regular filesystem. $
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
Distributions such as Debian Live, Mandriva One, Puppy Linux, Salix Live and Slax use this combination. The AppImage project, which aims to create portable Linux applications, uses Squashfs for creating AppImages. The snap package system also uses Squashfs as its file container format. Squashfs is also used by Linux Terminal Server Project and ...
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
