1. A disjoint array computer (DAC) system, comprising: a central computer communicatively connected to a plurality of disjoint node computers in a network by a plurality of disjoint communication channels, wherein only the central computer has direct access to each of the plurality of disjoint node computers via the plurality of disjoint communication channels; wherein each disjoint communication channel is composed of a command channel and a data channel, wherein the command channel provides communication between the central computer and the disjoint node computers, and wherein the data channel provides the central computer access to a plurality of memory segments of the plurality of disjoint node computers; wherein any given memory segment is accessible by the central computer or by the specific disjoint node computer to which it is connected via commands sent by the central computer over the disjoint command channel but is never directly accessible and completely isolated physically from all other disjoint node computers; wherein a choice of exclusive access to each memory segment is solely determined by the central computer; wherein the plurality of disjoint node computers act as servers with a common client being the central computer; and wherein both the central computer and the plurality of disjoint node computers share an enclosure.
