Document Summary

Any material substance that carries electronic signal to support comms. The broader the bandwidth, the more info exchanged. Broadband comms: system that can exchange data quickly. Broadcast over airwaves as form of electromagnetic radiation. Near field comms (nfc): short range wireless connectivity tech designed for cells and credit cards. Ultra-wideband (uwb): transmission of short electromagnetic pulses 50-1000 picoseconds. Wireless adapter translates data into radio signal and transmits with antenna. Terrestrial microwaves transmitted by line of sight devices. Low earth orbit (leo) satellite system employs many satellites. Long term evolution (lte): standard for wireless comms for cells. Worldwide interoperability for microwave access (wimax): 4g alt. Computer network: comms, devices, and software to connect 2+ computer systems. Star network: connect to one central device (hub node) Distributed processing: remote locations but connected by network. Multiple computer platforms dedicated to special functions. Server only sends data the satisfies requests.
