In Unix-like operating systems, a loop device, vnd (vnode disk), or lofi (loop file interface) is a pseudo-device that makes a computer file accessible as a block device. Before use, a loop device must be connected to an existent file in the file system .
If this device receives its own signal back, this proves that the circuit is functioning. A hardware loop is a simple device that physically connects the receiver channel to the transmitter channel. In the case of a network termination connector such as X.21, this is typically done by simply connecting the pins together in the connector.
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. $

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.

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.
