technology to use?

Bluetooth
B.
802.11
C.
802.11b
D.
Infrared
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 connections.
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 1 Mbps.
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.
