MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Piconet. A collection of devices connected via Bluetooth technology in an ad hoc fashion. A piconet starts with two connected devices, such as a PC and cellular phone, and may grow to eight connected devices. All Bluetooth devices are peer units and have identical implementations.

Detailed explanation-2: -Bluetooth devices can create both point-to-point and point-to-multipoint connections. A connection with two or several (maximum 8 devices) devices is a piconet where all devices follow the same frequency-hop scheme. To avoid interference between devices, one of the devices automatically becomes a master of the piconet.

Detailed explanation-3: -Bluetooth is a personal area network (PAN) standard that is lower power than 802.11. It was originally specified to serve applications such as data transfer from personal computers to peripheral devices such as cell phones or personal digital assistants.

Detailed explanation-4: -Bluetooth Personal Area Network (PAN) is a technology that enables you to create an Ethernet network with wireless links between mobile computers, mobile phones, and handheld devices.

Detailed explanation-5: -A wireless personal area network (WPAN) is a group of devices connected without the use of wires or cables. Today, most PANs for everyday use are wireless. WPANs use close-range wireless connectivity protocols such as Bluetooth.
