The present invention provides a teaching material having an identification unit and a teaching-material communication system. A signal is produced when any component fails, thereby alerting the operator of the need to replace the failed component. The coprocessor executes the instructions and initiates transmission of a set of execution results corresponding to the set of instructions to the processor unit’s functional unit. According to one embodiment, the vertical resources and services may comprise transport services capability architecture, virtual network capability architecture, security capability service architecture and quality of service architecture. The strut connects the torque box to the engine casing.
