In this comprehensive guide, we will delve into IoT one mark questions in detail, and equip you with the knowledge and skills required to ace them with ease.

What are IoT one mark questions?

IoT one mark questions are typically objective-type questions with a single correct answer. They test the basic knowledge and understanding of a student in IoT, and cover topics such as sensors, actuators, protocols, connectivity, security, and applications. Some examples of IoT one mark questions are:

• What is a sensor in an IoT system?
• What is the role of an actuator in an IoT system?
• What is MQTT, and how is it used in IoT?
• What is the difference between Wi-Fi and Bluetooth in IoT?
• What are some common security threats to an IoT system, and how can they be mitigated?
• What are some real-world applications of IoT?

Answering these questions correctly requires a sound understanding of the underlying concepts, and familiarity with the latest trends and technologies in IoT.

How to prepare for IoT one mark questions?

Preparing for IoT one mark questions requires a structured approach that covers all the essential topics and concepts. Some of the key steps that students can take to prepare for IoT one mark questions are:

1. Understand the basics: IoT is a vast field, and it’s essential to have a strong foundation in the basics before moving on to advanced topics. Students should spend sufficient time learning about sensors, actuators, protocols, communication, and other related concepts.
2. Stay up-to-date: IoT is a rapidly evolving field, and new technologies and trends emerge frequently. It’s crucial to stay abreast of the latest developments and updates, and to read relevant blogs, articles, and research papers regularly.
3. Practice, practice, practice: One mark questions require quick and accurate recall of information. Students should practice solving as many one mark questions as possible, from various sources such as textbooks, question banks, and online forums. They should also attempt mock tests to simulate exam conditions and evaluate their performance.
4. Revise regularly: It’s essential to revise the concepts and topics regularly to avoid forgetting them. Students should create a study plan that includes regular revision sessions and stick to it.

Examples of IoT one mark questions:

Here are some examples of IoT one mark questions, along with their respective solutions:

1. What is a sensor in an IoT system?
   Solution: A sensor is a device that detects and measures physical or environmental parameters such as temperature, pressure, humidity, light, motion, etc. Sensors are used to collect data in an IoT system and send it to the cloud or a local gateway for further processing.
2. What is the role of an actuator in an IoT system?
   Solution: An actuator is a device that receives commands from the cloud or a local gateway and performs an action such as turning on a switch, rotating a motor, or opening a valve. Actuators are used to control the physical world in an IoT system based on the data collected by sensors.
3. What is MQTT, and how is it used in IoT?
   Solution: MQTT (Message Queuing Telemetry Transport) is a lightweight publish-subscribe messaging protocol that is commonly used in IoT for reliable, low-latency communication between sensors, gateways, and cloud services. It allows devices to send and receive data in a secure and efficient manner, even in low-bandwidth environments.

Conclusion:

IoT is a rapidly growing field, and mastering IoT one mark questions is essential for students who want to build a successful career in this domain. By understanding the basics, staying up-to-date, practicing regularly, and revising regularly, students can prepare themselves to answer any IoT one mark question with ease. Besides, IoT professionals can also benefit from having a sound grip on one mark questions since it can make a significant difference in securing a job or promotion. We hope this comprehensive guide has equipped you with the necessary insights and skills to excel in your IoT endeavors.
