COMPUTER NETWORKING

Detailed explanation-1: -WiFi offers greater bandwidth in data transfer and is faster than Bluetooth. WiFi comes under the IEEE 802.11 network specification. IEEE 802.11a standard WiFi communication offers a 54 Mbps data transmission rate, whereas IEEE 802.11n gives 600 Mbps.

Detailed explanation-2: -A bandwidth of 1000 KHz and operating between 500 to 1600 kHz is used for Standard AM broadcasts. FM broadcasts use a bandwidth of just 20 MHz ranging from 88-108 MHz. Televisions use a bandwidth of 18 MHz in 54-72 MHz range for VHF and use a bandwidth of 400 MHz in 420-890 MHz for UHF frequencies.

Detailed explanation-3: -You can see in Table 2.1 that traditional twisted-pair affords the lowest bandwidth (i.e., the difference between the highest and lowest frequencies supported), a maximum of 1MHz, whereas fiber optics affords the greatest bandwidth, some 75THz.
