IrDA (Infrared Data Association). An internaltional organization that creates and promotes inter-operable, low cost, infrared data interconnection standards that support a walk-up,point-to-point model. The IrDA protocol is designed to support transmission of data between two devices over short-rangepoint-to-point infrared at speeds between 9.6Kbps and 4Mbps.

ISP (Internet Service Provider). A company that provides customer access to the Internet and the World Wide Web for a fee.
