Match the LIST-I with LIST-II LIST-I (Concept) LIST-II (Example) A. Internet…

Concept: The internet is usually described in successive stages, and each stage is named after the kind of entity the network mainly connects. In the internet of content stage the network links documents and information, so a user's activity is retrieving material that already exists. In the internet of people stage the network links users to one another, so activity is creating, sharing and interacting. In the internet of things stage the network links physical objects fitted with sensors and connectivity, so the objects themselves generate and exchange data without a person typing anything. Separately from these stages, network of networks is the structural definition of the Internet: many independently owned networks joined together through common protocols such as TCP/IP.

Applying the concept to each entry:

1. Internet of content connects information to users, so its example is an act of information retrieval: searching ‘Taj Mahal’ on Google (IV).

2. Internet of people connects users to one another, so its example is the platform class built for user-to-user interaction: social media (I).

3. Internet of things connects sensor-equipped physical objects, so its example is a wearable device that senses and transmits on its own: smartwatch (II).

4. Network of networks describes the architecture in which many separate networks interconnect, so its example is the Internet itself (III).

Cross-check by elimination of the wrong axis:

Each of the three stage concepts must take a concrete user-level example, and only the structural concept can take the Internet itself; no other assignment satisfies both constraints. The correct pairing is therefore A-IV, B-I, C-II, D-III.
