What is an infrared port?
Infrared technology allows a device to “beam” information to another device via an infrared port. While infrared has been around since the 1950s in the form of remote controls, computer technology has created a whole new set of infrared-based communications.Infrared DefinitionInfrared consists of light waves that are invisible to the naked eye, using a frequency just below visible red light. Light waves can travel at different speeds and vibrate at different frequencies. In infrared communications, the digital instructions on the sending device are converted to light waves, which are then transmitted or “beamed” to the receiving device, where they are converted back to digital format.Infrared Port DefinitionAn infrared port is the place on a device that sends and/or receives these light waves. A TV remote control, considered a uni-directional device, uses its infrared port to send commands to the TV. The bi-directional infrared port on a PDA is a wireless serial port that can send or r
An infrared port is a port that can send and receive data using infrared light, usually using the IrDA protocol. Infrared ports were once common on laptop computers, PDAs, and cell phones, but are being displaced by RF technologies, such as Bluetooth. They are still common in remote controllers of various home and office equipment, such as televisions, DVD players, amplifiers etc.
