MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).

Detailed explanation-2: -Short-range wireless technologies include Bluetooth, Wi-Fi, near-field communication (NFC), LPWAN, ultra-wideband (UWB) and IEEE 802.15. 4. They are implemented by chips fabricated as RF CMOS integrated circuit (RF circuit).

Detailed explanation-3: -Short-region wireless technology refers to the technology that can communicate wirelessly within a smaller diameter region, within a minimum level of one millimeter. The common short-region wireless communication modes are UWB, Wi-Fi, ZigBee and bluetooth.

Detailed explanation-4: -Bluetooth is a wireless communication technology standard used for exchanging data between fixed and mobile devices over short distances. It uses UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).

Detailed explanation-5: -Wi-Fi. Wi-Fi utilizes the 2.4GHz and 5GHz bands and features fast communication speeds. This, combined with a communication distance of about 100m, make it the preferred method for implementing a wireless network for connecting to the internet in the home.
