The data destruction machine is a desk-top, portable unit with a short cycle time, pluggable into a wall outlet. Multiple host machines may each contain an agent that detects possibilities of security threats based on raw data sensed locally at that host. The second P type epitaxial layer is connected to a ground terminal via the first P type epitaxial layer, the P well, a p+ diffusion region, a via and a wire. The data driver receives the differential signal, restores the video signal from the differential signal, and supplies the restored video signal to the address electrode of the plasma display panel. The software architecture includes a plurality of layers arranged in order from layers providing higher level services to layers providing lower level services, at least one software module in each layer, and interface means for permitting communication among software modules pursuant to a set of defined dependency rules.
