Hot potato routing is a routing technique enabling packet routing without storing them in buffers. The hot potato routing technique continuously transfers data packets until reaching their destination without the packets having to wait or being stored in a buffer. Any router configured for hot potato will immediately route the packet upon... Read more
IR-enabled devices are known as IrDA devices because they conform to standards set by the Infrared Data Association (IrDA). IR light-emitting diodes (LED) are used to transmit IR signals, which pass through a lens and focus into a beam of IR data. The beam source is rapidly switched on and off for data encoding. The IR beam data is received by an IrDA device equipped with a silicon photodiode. This receiver converts the IR beam into an electric current for processing. Because IR transitions more slowly from ambient light than from a rapidly pulsating IrDA signal, the silicon photodiode can filter out the IrDA signal from ambient IR. IrDA transmitters and receivers are classified as directed and non-directed. A transmitter or receiver that uses a focused and narrow beam is directed, whereas a transmitter or receiver that uses an omnidirectional radiation pattern is non-directed.
