- A. Smart Meter
- B. ATM
- C. Digital Lock
- D. Web
Answer:- C. Digital Lock
Explanation – A Digital lock allows us to use our smartphones to lock and unlock our door remotely at our homes or our businesses
3) The function/functions of an IoT Gateway is/are to?
- A. Forward packets between LAN and WAN and on the IP layer
- B. Connect IoT LAN to a WAN
- C. Both (a) and (b)
- D. None of the Above
Answer:- C. Both (a) and (b)
Explanation – The functions of an IoT Gateway are to forward packets between LAN and WAN on the IP layer and to connect the IoT LAN to a WAN.
4) Multi-homing is the concept where a node can be connected to multiple networks for ______.
- a. Reduced Reliability
- b. Improved Reliability
- c. None of these
- d. Both (a) and (b)
Answer:- b. Improved Reliability
Explanation – Multi-homing is the concept where a node can be connected to multiple networks for Improved Reliability, by connecting a device to multiple networks simultaneously, such as connecting to both a wired and wireless network, or by connecting to multiple wireless networks. This can provide increased availability and redundancy in case one network fails.
5) A Passive Infrared Ray (PIR) sensor is used for _______.
- a. Humidity Detection
- b. Tilt Detection
- c. Obstacle Detection
- d. Smoke Detection
Answer:- c. Obstacle Detection
Explanation – A PIR sensor (Passive Infrared Ray sensor) is used for motion detection. It detects motion by sensing changes in infrared radiation, which is emitted by all objects with a temperature above absolute zero. PIR sensors are commonly used in security systems, automatic lighting control systems, and other applications where motion detection is needed. It can be used to detect the presence of people or animals, as well as to trigger alarms or other actions.
6) For which of the following, Vector Sensors are required to measure or sense them?
- a. Color, Pressure, Temperature
- b. Orientation, Image
- c. None of these
- d. Both (a) and (b)
Answer:- a. Color, Pressure, Temperature
Explanation – Color, Pressure, Temperature Vector Sensors are used to measure or sense physical quantities that have both magnitude and direction. They are able to measure multiple types of physical quantities, such as color, pressure, temperature, and many others. Vector Sensors typically use multiple sensing elements to measure different aspects of the physical quantity, and then combine these measurements to determine the overall value of the physical quantity.
7) The sensitivity of a sensor under real conditions ma called _____?
- a. Maximal Error
- b. Minimal Error
- c. Median Error
- d. Sensitivity Error
Answer:- d. Sensitivity Error
Explanation – The sensitivity of a sensor refers to the degree to which a sensor responds to changes in the quantity being measured. Sensitivity error is the measure of how much the sensor’s output deviates from the actual value under real-world conditions. The sensitivity error can be calculated by comparing the sensor’s output to the actual value of the quantity being measured. Sensors with high sensitivity are able to detect small changes in the quantity being measured, while sensors with low sensitivity are less able to detect changes.
8) A random deviation of the signal that varies in time is called ____ .
- a. Noise
- b. Sound
- c. Bias
- d. None of these
Answer:- a. Noise
Explanation – A random deviation of the signal that varies in time is called noise. Noise can be caused by a variety of factors, such as electrical interference, thermal fluctuations, or other sources. Noise is considered to be undesirable in most applications because it can make it difficult to accurately measure or interpret the signal. It can be added to a signal during the measurement process or can be intrinsic to the sensor. There are many techniques to reduce the effect of noise such as filtering and signal processing.
9) A Relay Switch is an example of _____.
- a. A Sensor
- b. An Actuator
- c. A Transducer
- d. None of These
Answer:- b. An Actuator
Explanation – A Relay switch is an example of an actuator. Actuators are devices that convert an electrical signal into a mechanical movement. They are used to control or manipulate a system or process. A relay switch is an electromechanical switch that can be controlled by an electrical signal, such as a voltage or current. When the relay switch receives an electrical signal, it moves a mechanical contact to make or break an electrical connection, allowing current to flow to a load or shutting it off. Actuators are used in a variety of applications, including industrial automation, home appliances, and vehicles.
10) What is a Pneumatic Actuator?
- a. It is a type of actuator driven by compressed air or vacuum
- b. It is a type of actuator driven by fluid
- c. It is a type of actuator driven by solid
- d. None of these
Answer:- a. It is a type of actuator driven by compressed air or vacuum
Explanation – A Pneumatic actuator is a type of actuator that is driven by compressed air or vacuum. These actuators use the force generated by compressed air or vacuum to produce linear or rotary motion. Pneumatic actuators are widely used in industrial and commercial applications because they are simple, reliable, and relatively inexpensive. They are typically used to operate valves, cylinders, and other mechanical devices. They are also used in some automobiles, aircraft and home appliances.
