Question
Which of the following protocols is widely used for
low-power, short-range communication in IoT devices?Solution
Bluetooth Low Energy (BLE) is designed for low-power, short-range communication, making it ideal for IoT devices like wearables and smart home gadgets. BLE operates within the 2.4 GHz ISM band and consumes minimal energy, ensuring long battery life for connected devices. • Example: A fitness tracker uses BLE to sync data with a smartphone. The protocol ensures reliable communication without draining the device's battery. ________________________________________ Why Other Options Are Incorrect: 1. HTTP: HTTP is heavy and unsuitable for low-power IoT communication. 2. FTP: FTP is used for file transfers, not for real-time IoT communication. 3. SOAP: SOAP is verbose and not optimized for lightweight, resource-constrained IoT environments. 4. SMTP: SMTP is for email transfer and lacks IoT-specific optimizations.
?2 - 12.5% of 647.99 = 24.98% × 363.97 + 5% of 1059.98Â
29.88% of 3599.90 + 5/12 of 2399.81 – 34.81% of 1200.18 = ?
