When the alarm of your smartphone rings in the morning, you wake up and tap it to stop the alarm which causes your geyser to be switched on automatically. The smart mirror in your bathroom shows the day's weather and also indicates the level of water in your overhead tank. After you take some groceries from your refrigerator for making breakfast, it recognises the shortage of stock in it and places an order for the supply of fresh grocery items. When you step out of your house and lock the door, all lights, fans, geysers and AC machines get switched off automatically. On your way to office, your car warns you about traffic congestion ahead and suggests an alternative route, and if you are late for a meeting, it sends a message to your office accordingly. In the context of emerging communication technologies, which one of the following terms best applies to the above scenario ?

1. The scenario describes a network of interconnected everyday objects (smartphone, geyser, smart mirror, refrigerator, lights, fans, AC machines, car) that can communicate with each other and perform actions automatically based on triggers or data analysis (e.g., alarm stopping triggers geyser, refrigerator detects shortage and places an order, locking door switches off appliances, car detects traffic and suggests alternative route). 2. This concept of embedding sensors, software, and connectivity into physical objects to enable them to collect and exchange data is the core idea behind the Internet of Things (IoT). Option (B) accurately reflects this interconnected network of smart devices. 3. Option (A) Border Gateway Protocol (BGP) is a routing protocol used to exchange routing information between autonomous systems on the Internet. 4. Option (C) Internet Protocol (IP) is the principal communications protocol for relaying datagrams across network boundaries. 5. Option (D) Virtual Private Network (VPN) creates a secure, encrypted connection over a less secure network, like the internet. 6. While IP is used within the IoT, the overall scenario described is best captured by the term Internet of Things.
