Which Type Of Port Transfers Data Using Light Waves?

Which type of port transfers data using light waves?

Answer: IrDA is the port that transfers data using the light waves.it is described as a standard through which the data is transmitted with the help of an infrared port. The speed is almost the same as the normal parallel ports. Those who developed the port use wireless technology for two-device connectivity.

What is IrDA port?

IrDA stands for the infrared Data Association which used infrared light beams for the information transmission and also needs a direct line of sight and the range for its proper working is less. For the protocol set which is complete IrDA gives the specification for the wireless communication. The port sports Bluetooth which is a benefit for the long-distance mostly around 30 feet and also the Omni-directional.

The main purpose for using the IrDA is its specification of the wireless data transfer with the principles of point-to-shoot within the range of the last one meter. The port is used in many things as the TV, DVD players use the controls of IR .few mobile phones are also able to use the IR port to manage the electronic devices but it can also use the additional software.it can guarantee the transfer of data, the line-of-sight, and the error range is low which is the reason for its efficiency.

The communication is cheaper and quite adopted for the shorter ranges as 1-3m through wireless. Mostly the technology is used in the electronic consumer, automobiles, OC medical devices, home appliances, and any kind of commercial services. The IrDA protocol stack is the model of the open system interconnection and a few of its specifications are discussed in the following:

IrPHY (Infrared physical layer)

The ability is specified to assist point-to-point communication among the electronic devices. It gives the facility of optical media interface for SIR (serial infrared) transmission and it is the part of the first layer of the OSI model.

Infrared link access protocol (IrLAP)

It is the facility of the second layer of the OSI model of IrDA.it is present between the IrPHY and IrLMP layers.it shows the data link layer.

Infrared link management protocol (IrLMP)

This is the third layer of the IrDA abilities.it can describe the link management multiplexer and also the link management information access service.

Transport protocol (TinyTP) 

This non-obligatory protocol targeted inside the fourth layer lies on the pinnacle of the IrLMP layer.

 Infrared communication protocol (IrCOMM)

The IrCOMM protocol targeted inside the 5th layer shall we the infrared tool act like both a serial or parallel port.

 Infrared Financial Messaging (IrFM) 

This protocol targeted with inside the 6th layer is a Wi-Fi charge widespread evolved via

way of means of the Infrared Data Association.
