What is device management in Linux?

Udev is the device manager for the Linux 2.6 kernel that creates/removes device nodes in the /dev directory dynamically. It is the successor of devfs and hotplug. It runs in userspace and the user can change device names using Udev rules. Udev depends on the sysfs file system which was introduced in the 2.5 kernel.

The reverse data path is also used, from the physical device through the device driver, the device file, and then to an application or another device.
