A network apparatus is capable of calculating positions on a display screen where connecting states of network apparatuses connected to a network are displayed on the basis of connecting information of the network apparatuses on the network and peripherals connected thereto and displaying the positions. In addition, a controller is provided for controlling in such a manner that when it is necessary to change the display positions by a display change instruction, the display positions are again calculated and displayed on a display screen, and when a reduced display is designated, the peripherals connected to the network apparatus on the network are not displayed, and when an expanded display is designated, the peripherals connected to the network apparatus on the network are displayed.
