Explanation

Bluetooth is the best wireless technology to connect peripheral devices, such as a printer and mouse, to a laptop.Bluetooth is a standard for very low powered and short-range radio It is used to link personal access devices (PDA), mobile phones and laptops, and provides them with Internet access via hot spots. Bluetooth uses the 2.4 Ghz spectrum with a data rate of about As a radio technology, Bluetooth does not require line of sight like an infrared connection requires. The maximum transmission range of Bluetooth is around 10 meters. High-powered Bluetooth would extend the range to 100 meters. Answer options B and C are incorrect. These are the latest networking specifications for wireless local area networks (WLANs) developed by the Institute of Electrical and Electronic Engineers. Answer option D is incorrect. Infrared medium transmits data at almost the same rate as a parallel port does. Infrared data transfer requires a clear line of sight between devices, and the communicating devices must be in close proximity. Although infrared technology can be used to connect peripherals to a computer, Bluetooth technology is the best for this purpose.
