Flipkart is not an example of social networking. It is an e-commerce platform that allows users to buy and sell products online. Flipkart operates as a marketplace for a wide variety of goods, including electronics, clothing, home goods, and more.

So, while Flipkart may have some social features like customer reviews or social media sharing, its primary purpose is e-commerce, not social networking.

The Internet is often described as a network of networks because it is made up of millions of interconnected computer networks that communicate with each other. These networks can range from small local area networks (LANs) to large-scale wide area networks (WANs) operated by Internet Service Providers (ISPs), organizations, and data centers.

The key idea behind the Internet being a "network of networks" is that it enables the exchange of data and information between different networks, using common protocols like TCP/IP (Transmission Control Protocol/Internet Protocol). This allows devices and systems, regardless of their location or the type of network they belong to, to connect and communicate with each other globally.

In short, the Internet is a vast, global system that connects countless smaller networks together, making it possible for users to access websites, send emails, share files, and interact in many other ways online.

Correct Answer: A) True

Correct Answer: B) False

By turning your phone or a dedicated mobile hotspot device into a hotspot, you can provide internet access to multiple devices, as long as they are within range and connected to the hotspot.
