What is an infrared data receiver on a laptop?
An infrared data receiver (usually called a transceiver, since it can send and receive) is a dated inter-device communication standard that allowed line-of-sight wireless communication between equipped devices. It worked the same way that a remote control works. It sends out pulses of light in the infrared spectrum that are read by another device. These pulses constitute a stream of digital information. This communication method is rather dated, and not many devices support it anymore. It saw the most use in Palm and Windows Mobile devices even into the early 21st century, but has now been eclipsed by Bluetooth technology which provides faster transfers, longer transfer distances, and no need for line-of-sight between devices.
