Why each option
IrDA is a short-range wireless technology that allows data transfer between devices and is also commonly used for remote control functionalities in consumer electronics.
IrDA is specifically designed for short-range line-of-sight communication, typically up to 1 meter, making it suitable for transferring data between devices in close proximity.
While IrDA enables data transfer, its primary design is not for full computer-to-computer control over a wireless connection like more robust wireless protocols.
IrDA is widely used in remote control units for consumer electronics, allowing a remote to control features of another device by transmitting infrared signals.
IrDA and Bluetooth are distinct wireless technologies; an IrDA device cannot identify Bluetooth devices, which operate on a different radio frequency spectrum.
