The correct answer is (a) Both share data, but only Wi-Fi does this using radio frequencies.Wi-Fi and Bluetooth are both wireless communication technologies, but they have some key differences:1. Radio frequency: Wi-Fi uses radio frequencies to transmit data, while Bluetooth uses a lower frequency radio signal.2. Range: Wi-Fi has a much longer range than Bluetooth, typically up to 100 meters (328 feet) for Wi-Fi and up to 10 meters (33 feet) for Bluetooth.3. Data transfer speed: Wi-Fi generally has higher data transfer speeds than Bluetooth, with typical speeds ranging from 1 Mbps to 1 Gbps for Wi-Fi and up to 2 Mbps for Bluetooth.4. Power consumption: Bluetooth generally consumes less power than Wi-Fi, making it more suitable for battery-powered devices.5. Use cases: Wi-Fi is commonly used for internet connectivity and data transfer between devices, while Bluetooth is often used for short-range communication between devices, such as connecting a smartphone to a wireless headset or transferring files between devices.So, the correct answer is (a) Both share data, but only Wi-Fi does this using radio frequencies.
