What is IrDA?
Short for Infrared Data Association, a group of device manufacturers that developed a standard for transmitting data via infrared light waves. Increasingly, computers and other devices (such as printers) come with IrDA ports. This enables you to transfer data from one device to another without any cables. For example, if both your laptop computer and printer have IrDA ports, you can simply put your computer in front of the printer and output a document, without needing to connect the two with a cable. IrDA ports support roughly the same transmission rates as traditional parallel ports. The only restrictions on their use is that the two devices must be within a few feet of each other and there must be a clear line of sight between them.
IrDA is an acronym for Infrared Data Association, a type of port installed on newer computers, printers, and other devices. IrDA port allows the devices to communicate wirelessly. IrDA port transmits data at almost the same rate as a parallel port does. IrDA data transfer requires a clear line of sight between devices, and the communicating devices must be in close proximity.
IrDA is an acronym for the Infrared Data Association, an organization which sets communications standards for infrared over small distances. IrDA has been around since 1993, as an overseeing body for a wide group of infrared technologies. Traditionally, infrared devices, such as old television remote controls, use a one-way beam. They send information out, but aren’t capable of receiving information back. Bi-directional infrared devices are substantially more complicated than one-way emitters, and so IrDA formed to help maintain a set of standards everyone could stick to. IrDA devices include printers, cameras, handheld portables, smart remotes with display screens, cell phones, and even new smart bank cards. IrDA devices are quite cheap, with the parts that make them up costing only pennies, making them attractive for use in a wide range of devices. Because IrDA beams are directional, they are relatively secure from eavesdropping and other unauthorized forms of access to information s
IrDA is an international organization that creates and promotes interoperable, low cost, infrared data interconnection standards that support a walk-up, point-to-point user model. IrDA is a protocol suite designed to support transmission of data between two devices over short-range point-to-point infrared at speeds between 9.6 kilobits per second (Kb/s) and 4Mb/s. IrDA is that small semitransparent red window you may have wondered about on your notebook computer. Over the last three years, the members of the IrDA have been very successful at getting IrDA hardware deployed in a large number of new notebook computers. One of the reasons for this has been the simplicity and low cost of IrDA hardware. Unfortunately, until recently, the hardware has not been available for applications programmers to use because of a lack of suitable protocol drivers. Microsoft Windows CE 1.0 was the first Windows operating system to provide built-in IrDA support. Windows 2000 and Windows 98 now also include
