Internet of Things MCQ

IoT stands for Internet of Things. Connecting everyday things embedded with electronics, software, and sensors to the internet enables them to collect and exchange data.

Benefits of IoT:

  • Efficient resource utilization
  • Minimizing Human effort
  • Saves time
  • Development of AI through IoT
  • Improved security


IoT Features:

  • Connect various things to the IoT Platform
  • Analyze the data collected and use it to build business intelligence
  • Integrate various models to improve user experience.


IoT Ecosystem:

Basic architecture:

  • Application layer: Responsible for delivering application-specific services to the user. Defines an application in which the IoT can be deployed.
  • Network layer: Responsible for connecting smart things, network devices, and servers. Also used for transmitting and processing sensor data.
  • Perception layer: Sensors sense and gather information about the environment. Senses physical parameters or identifies other objects in the environment.


Application of IoT:

  • Energy conservation
  • Smart Transport
  • Social life and entertainment
  • Supply chain and logistics
  • Health and fitness
  • Smart environment
  • Home automation
  • Smart agriculture


IoT Sensor:

It is a device that captures real-world data and translates it into a piece of information that could be interpreted by other instruments. As the name suggests, sensors react to stimuli – be it changes in temperature, sound, or different properties. Hence a sensor in an IoT system senses the desired physical quantity and converts it into electrical signals transmitted to the central cloud-based server directly or via an on-site microcontroller.


Types of Sensors:

  • Temperature sensor
  • Humidity sensor
  • Proximity sensor
  • Level sensor
  • Gyroscope.


Features of Sensors:

  • Range
  • Accuracy
  • Sensitivity
  • Resolution
