Abstract: An apparatus and method for detecting a connection to a data transmission network functions by detecting the network signal energy on a network cable while avoiding the problems of excessive power consumption and generation of excessive electrical noise. By monitoring the receive network lines and determining if there is electrical energy on the cable in the form particular to the type of network supported by the network adaptor card, the host computing device can power-down the transceiver associated with the network adaptor card until an active network connection is detected.

Abstract: A novel virtual desktop system organizes open applications of a computer into groups of programs that perform common functions or tasks. The groups of programs are called Desktops and the virtual desktop system provides a Desktop Manager for assigning ranges of display screen coordinates to these Desktops, and then assigning open applications to them. Specifically, the Desktop Manager is a system software program that contains a plurality of Desktop groups and that provides a user interface for managing the display of selected open applications assigned to the Desktops. These selected open applications are displayed in application windows on a display screen of the computer when switching between Desktops in the virtual desktop system.
