A user terminal and an image communication method and apparatus include outputting a captured image without performing left-and-right reversion when the captured image includes a symbol. The transceiver is arranged to mate with the first and second connectors so that at least some converted electrical signals are transmitted to the first connector and so that at least some electrical signals received from the cable are transmitted to the second connector. The storage controller driver receives a first IO transaction request. The pipelined switch operates on several packets in parallel while determining each packet’s routing destination. A user at the client computer may act on the data based on the attached risk level. The coupling structure enables to precisely align the optical waveguide and the optical device so that an optical-alignment error can be reduced within a range of a few \u03bcm.
