The present invention provides an interactive graphical user interface patch environment for installing a patch on the targeted systems. The device can optimize the execution of commands by changing the order of execution of write commands that are insensitive to write barrier command. The lighting module is disposed at the first side and operable to emit light outwardly of the casing unit and away from the first side of the casing unit. The integrated network device further includes a wireless protocol interface for receiving, transmitting, and processing voice communications. The second embodiment describes a device and method for converting high frequency analog signals greater than approximately 10 GHz into digital signals. With the set of the protrusion, the electrical connection between the electrical connector and a chassis panel may be improved and reliable.
