A multiport memory has a plurality of RAMs and a port expansion unit electrically connected to access ports of the RAMs. At least one task is executed on a server, where each task includes a task identifier and a priority value. In another implementation, an anode plate of a field emission display includes a transparent piece of the field emission display and a plurality of phosphor lines formed on the transparent piece. The substrate is reduced to provide a device layer for fabricating a microelectronic device. A frame structure positioned within a resilient seal includes longitudinally elongate elements which may be of spring material, malleable material or heat recoverable material so as to accomplish an initial insertion state and an expanded anchoring state. A single message processing system can appear as a large number of virtual message sendingunits.
