Match List I with List II :

List IList II
(a) Sensors(i) Analytical tools that improve the ability to describe phenomenon
(b) Networks(ii) Commonly accepted prescriptions for action
(c) Augmented intelligence(iii) A device that generates an electronic signal from a physical condition
(d) Standards(iv) A mechanism for communicating an electronic signal

Choose the correct answer from the options given below :

  • A.(a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
  • B.(a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)
  • C.(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
  • D.(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

Answer: C

The correct matching is (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii).

  • Sensors: a device that generates an electronic signal from a physical condition, such as temperature or pressure (iii).
  • Networks: the mechanism for communicating that electronic signal from place to place (iv).
  • Augmented intelligence: analytical tools that improve the ability to describe, predict and act on the phenomenon the data represents (i).
  • Standards: commonly accepted prescriptions for action, technical and regulatory, that let devices and systems work together (ii).

These are the layers of the Internet of Things value chain. Options A and D pair sensors with standards, and option B swaps augmented intelligence and standards, so only C matches all four.
