IrDA

"IrDA" stands for "Infrared Data Association". It is an organization that deals with the development and standardization of technologies for wireless data transmission using infrared radiation. These technologies enable fast data transfer between various devices such as computers, mobile phones, printers and more, without the need for a physical cable connection.

IrDA has played a key role in setting standards for infrared communication protocols and devices. Using infrared radiation for wireless data transmission has several advantages, including safety (due to the limited range of infrared radiation), ease of use, and low cost.

For example, the IrDA standard defined communication protocols that enable wireless data transfer between a laptop and a printer via an infrared port. In this way, it was possible to transfer data quickly and conveniently without the use of cables.

However, nowadays technologies like Bluetooth and Wi-Fi have become much more popular for wireless data transfer, and therefore the use of IrDA has gradually decreased. Nevertheless, IrDA has had a significant impact on the development of wireless communication technologies in the past.
