Abstract:
1. A download system, comprising; a server having: a server side transmitting and receiving means capable of performing transmission, a server side memory directly connected to said server side transmitting and receiving means and having DRAM or HDD for storing large-capacity data in said server side memory, a transmission side control means for making said server side transmitting and receiving means transmit requested data out of data stored in said server side memory according to a request from a client side, and a client having: a client side transmitting and receiving means for receiving data transmitted from said server side transmitting and receiving means, a download memory having DRAM or HDD into which large-capacity data received by said client side transmitting and receiving means are directly written and a reception side control means for indicating data to be downloaded to said server side and making the downloaded data be written into said download memory, in which said server side transmitting and receiving means and said client side transmitting and receiving means perform direct transmission and reception therebetween by means of a millimeter-wave transmission, at least one of said server side transmitting and receiving means is a circuit using an NRD guide (Non-radiative dielectric wave guide), and said circuit using an NRD guide (Non-radiative dielectric wave guide), comprises:
