INFRARED PORT ABCs

Infrared was discovered in the early 1800's by Sir William Hershel. He discovered upon moving a thermometer across the spectrum of colors that the heat would increase towards red. As he continued to move the temometer past the red the heating continued to rise. This area is what we call Infrared, or also known as "Below Red".

The Infrared port today or also commonly refereed to as the IRDA (Infrared Data Association) is a port much like what you would find on your TV/VCR remote. This port allows two computers or a computer and a device to communicate amongst each other without the use of wires.
