5. DLNA stands for Digital Living Network Alliance.
- Reason: This statement is true; DLNA does stand for Digital Living Network Alliance.
6. Which of the following are the functional layers in smart parking?
- Reason: Information collection, system deployment, and service dissemination are indeed the functional layers in smart parking, so option "d. All of these" is correct.
7. Which of the following statements are true about the HAN standards?
- Reason: Statements I and III are correct. IEEE802.15.4 defines the physical and MAC layers, while Zigbee defines the network layer. Hence, option "b. Statements I and III" is correct.
8. Which of the following are true about X-10?
- Reason: Statements I and III are correct. X-10 allows remote control of compliant transmitters and is adopted by GE. So, option "c. Statement I and III" is correct.
9. Fill in the blank. ____________ enables vehicles to wirelessly share a diverse range of information.
- Reason: V2X (Vehicle-to-Everything) Paradigm enables vehicles to share information wirelessly with other vehicles and infrastructure, facilitating communication in diverse scenarios.
10. Which of the following is a property of Vehicular Ad-hoc Networks?
- Reason: Vehicular Ad-hoc Networks (VANETs) are indeed based on DSRC (Dedicated Short Range Communication) and WAVE (Wireless Access in Vehicular Environments), and they aim to provide low-latency communication in vehicular environments, so option "d. All of these" is correct.
11. Knob is a switch type of INN.
- Reason: This statement is false. A knob is not a switch but a rotating control input commonly used for adjusting settings like volume or brightness.
12. Which of the following is responsible for central coordination in Body-brain architecture?
- Reason: The INN (Internal Neural Network) is responsible for central coordination in Body-brain architecture.
13. Which of the following stands for DSRC?
- Reason: DSRC stands for Dedicated Short Range Communication.
14. Ad-hoc is a domain of VANET.
- Reason: This statement is true. Ad-hoc communication is an essential aspect of VANETs (Vehicular Ad-hoc Networks).
15. What are the disadvantages of V2X communication?
- Reason: Tracking of movement is a potential disadvantage of V2X communication, as it may raise privacy concerns when vehicles' locations and movements are shared. Increased traffic safety and efficient fuel use are potential advantages, not disadvantages.
Fog Computing: A Paradigm Shift in IoT
Fog computing is a concept that has gained immense importance in recent years, especially in the realm of IoT. It refers to the practice of extending cloud computing capabilities to the edge of a network, closer to the data source. This paradigm shift brings several advantages to the IoT landscape.
Fog computing reduces latency significantly, ensuring faster response times for critical applications. This is particularly crucial in scenarios where real-time data processing is essential, such as autonomous vehicles or industrial automation.
Moreover, it enhances data privacy and security by processing sensitive data locally, reducing the risk of data breaches during transmission to a remote cloud server. This is pivotal in an era where data privacy is a paramount concern.
Smart Cities: Paving the Way for a Sustainable Future
The concept of smart cities is no longer a futuristic idea but a tangible reality. In the context of IoT, smart cities leverage interconnected devices and sensors to optimize various aspects of urban life. From traffic management to waste disposal, IoT plays a pivotal role in transforming cities into efficient, sustainable, and livable spaces.
Smart city initiatives focus on enhancing resource management, reducing energy consumption, and improving the overall quality of life for citizens. The integration of IoT technology allows for real-time monitoring and data-driven decision-making, leading to more efficient urban planning and development.
Smart Homes: Where Comfort Meets Efficiency
The idea of a smart home, once a notion relegated to science fiction, has become an integral part of modern living. IoT has brought about a revolution in home automation, making our living spaces more convenient, energy-efficient, and secure.
Smart home devices, such as thermostats, lighting systems, and security cameras, can be controlled remotely through smartphones or voice commands. This not only adds to the convenience factor but also contributes to energy conservation by optimizing resource usage.
