Answer :- b
3. State whether the following statement is True or False.
Statement: The increasing number of devices in IoT is expected to result in an address crunch.
a. True
b. False
Answer :- a The statement is true. The increasing number of devices in the Internet of Things (IoT) is expected to result in an address crunch. As more and more devices get connected to the internet and the IoT ecosystem grows, there is a concern that the current Internet Protocol version 4 (IPv4) address space may become insufficient to accommodate all these devices. IPv4 has a limited number of unique IP addresses, and with the rapid proliferation of IoT devices, there is a risk of running out of available addresses.

Statement: The gateway has a unique network prefix, which can be used to identify them globally.
a. True
b. False
Answer :- a
5. Sometimes, when there is a need for the nodes to communicate directly to the Internet, ______________ can be used.

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.
11. Based on the data type, sensors are classified as _______________________.
a. Scalar and Vector/Multimedia
b. Only scalar
c. Both (a) and (b)
