A network loopback device i.e. lo is assigned the IP address, its is also known as localhost. It allows one to run network applications on the computer without need for a network card.

There are several webserver applications that are usefull in configuring the OS like webmin, swat and cups.

There are filesystem loop devices too. This allows one to mount a file as a block device. An example would be to mount an ISO file to examine its contents.
