udev is a generic kernel device manager. It runs as a daemon on a Linux system and listens (via netlink socket) to uevents the kernel sends out if a new device is initialized or a device is removed from the system.
In a nutshell UDEV is an replacement of DEVFS in user-space using sysfs and /sbin/hotplug. It will create and destroy /dev entries based on the current system configuration. It does this by watching the /sbin/hotplug events on the system, and reading information about these events from sysfs.
