The present invention is to allow display based on the setting positions of devices in selection of a desired device to be used, and facilitate selection considering the setting positions of the devices. The present invention can also display equipments so as to allow discrimination between an equipment included in an image processing apparatus and an equipment connected on a communication line. Equipments in a network environment are placed on the first floor (1F), the second floor (2F), and the third floor (3F) in a building and connected through a network (LAN 1300). For example, a computer (1310) collects device information including status information and setting position information from usable input/output devices. For example, status information representing “BUSY” and setting position information representing “3F-B block” are transferred from a virtual optical scanner (1302). The computer (1310) displays the connected input/output devices together with the setting position information obtained from the devices. An image processing apparatus (100) has various input/output devices including a reader unit (1), a printer unit (2), and an image input/output control unit (3). In addition, various input/output equipments (two optical scanner devices (1302, 1303) and three facsimile transmission/reception devices (1305, 1306, 1307)) are connected to the image processing apparatus (100) through a LAN interface unit (9) and the LAN (1300). A CPU (123) of a core unit (10) manages the input/output equipments to determine whether they are connected through the network. When a desired input/output equipment is to be selected, whether the input/output equipments are connected through the network is explicitly indicated.
