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 thermometer past the red the heating continued to rise. This area is what we call Infrared, or also known as "Below Red".The infrared Port is commonly called today or also commonly referred to as the IRDA (Infrared Data Association).Infrared port much like what you would find on
your TV/VCR remote. Infrared port allows two computers or a computer and a device to communicate amongst each other without the use of wires .In another sense you can say that infrared or IRDA port is a wireless serial port which uses Infrared or invisible light for transmission and reception of data.

Infrared port provides a wireless link for transferring information from kiosks to hand held devices such as PDAs which is a lightweight consumer electronic device that looks like a hand-held computer but instead performs specific tasks; can serve as a diary or a personal database or a telephone or an alarm clock etc. For example, a tourism kiosk with an infrared port can allow tourists to instantly download information about local attractions and restaurants to their PDA. Infrared port on laptop
computer can be used to transfer data to and from another computer or a mobile device like a PDA or mobile phone without wires over short distance. Infrared port will need a line of sight communication path, that is to establish a connection and for reliable communication infrared port consist of two devices should face each other. Not all laptops have infrared ports. Some have these built in the machine and for some if needed you will have to add an Infrared port device on USB port.
On some mobile phones, the infrared port can be on the top of the phone. On some Nokia phones for example such as the Nokia 3360, the power on switch is the infrared port too. A Dell Inspiron has its infrared port on the right side, a oval-shaped dark plastic window just between and have different shapes. Always ensure that you have the Infrared device enabled in CMOS(Complementary
metal–oxide–semiconductor).Ensure that the Infrared port is correctly aligned, pointing directly at each other and are no further than one foot.
- If the device trying to connect to the computer infrared port uses batteries, ensure they are working properly.
- Ensure no other Infrared devices are located in the same area. Some devices such as TV / VCR remotes or other Infrared devices can cause problems with the Infrared port on your computer.
- If you are attempting to install another Infrared device, ensure that the original Infrared device is completely uninstalled.
One kind of infrared ports was generic IR ports, these are the most common and include ports often found in desktop PCs and many laptops or on motherboards that support IrDA headers. If you have an older version of Windows, then you may already have a generic device configured. Infrared is also used to control a television set with a remote control.
Infrared data communication is an industry-sponsored organization set up in 1993 to create international standards for the hardware and software used in infrared communication links. Infrared data communication is playing an important role in wireless data communication due to the popularity of laptop computers, personal digital assistants (PDAs), digital cameras, mobile telephones, pagers, and other devices. Among existing uses or likely possibilities are:
- Sending a document from your notebook computer to a printer
- Exchanging business cards between hand held PCs
- Coordinating schedules and telephone books between your desktop and notebook computers
- Sending faxes from your notebook computer to a distant fax machine through a public telephone
- Digital cameras that can beam images into your computer
