1. Which of the following are the enablers of IoT?
- a. RFID
- b. Nanotechnology
- c. Sensors
- d. All of the these
Answer :- D All of the mentioned options are enablers of the Internet of Things (IoT): a. RFID (Radio Frequency Identification) allows objects or items to be uniquely identified using radio waves, enabling them to be tracked and managed within IoT systems. b. Nanotechnology plays a role in IoT by providing miniaturized components and devices, making it possible to create tiny sensors, processors, and actuators that can be integrated into various objects, enabling them to connect to IoT networks. c. Sensors are a crucial component of IoT, as they gather data from the physical environment and convert it into electronic signals, which can then be processed and utilized in various applications.

Certification Criteria for NPTEL Internet of Things Course
Average assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
7. The IPv6 notation uses ___________________ values.
a. Roman
b. Hexadecimal
c. Both (a) and (b)
d. None of these
Answer :- b
8. A _____________ detects (senses) changes in the ambient conditions or in the state of another device or a system, and forwards or processes this information in a certain manner.
a. Sensor
b. Actuator
c. Both (a) and (b)
d. None of these
Answer :- a
9. A microphone is an example of an _____________.
a. Input device and actuator
b. Only actuator
c. Only Transducer
d. Input device and transducer
Answer :- d
10. The ________________ of a sensor is the smallest change it can detect in the quantity that it is measuring.
a. Resolution
b. Bias
c. Noise
d. None of these
Answer :- a The resolution of a sensor refers to the smallest change in the quantity it is measuring that the sensor can detect and accurately represent. It represents the level of detail or precision with which the sensor can measure changes in the input parameter. Higher resolution sensors can detect smaller changes in the measured quantity, while lower resolution sensors have limitations in detecting fine variations. For example, in a temperature sensor with a resolution of 0.1°C, it can detect temperature changes as small as 0.1°C and accurately represent them in its output. Resolution is an important specification for sensors, especially when precise measurements are required in various applications, including IoT, automation, and scientific measurements.
