Systems and techniques for transmitting data stream to a client include transmitting a data segment from one of a plurality of nodes of a continuous media server to a client according to a scheduler on the node. For example, an injected non-polarized control current creates ferromagnetic conditions within the transistor base, enabling a small spin-polarized signal current to generate spontaneous magnetization of a larger output current. According to this selection, the at least one data processing apparatus transmits the processing request to the selected data processing apparatus, and receives data processed by the selected data processing apparatus. A driver engages clamping mechanism to clamp the two members together. The matching process itself occurs in two stages. Each set of prefetch registers includes a prefetch address register ; an offset register ; a termination register ; a status register ; and a returned data register.
