Identify which is not an element of IoT?

Here are the answers to the multiple-choice questions:

1. Identify which is not an element of IoT?

   • IoT elements typically include Things, Data, Process, and Security. While people interact with IoT, they are generally considered users or beneficiaries rather than a core technical element of the IoT system itself.
   • The correct option is a. People.

2. Internet of things is natural extension of ----------

   • The Internet of Things (IoT) naturally extends from Supervisory Control and Data Acquisition (SCADA) systems, which are early forms of networked industrial control and monitoring systems. IoT broadens this concept to a wider range of devices and applications using internet connectivity.
   • The correct option is c. SCADA.

3. The first and most commonly used smart, interactive IoT device is ....................

   • Automated Teller Machines (ATMs) have been networked, smart, and interactive for decades, connecting to central systems for transactions. They fit the broad definition of an IoT device and have been widely used globally for a long time.
   • The correct option is b. ATM.

4. IOT is evolved from .................... communication

   • IoT is fundamentally built upon the concept of Machine-to-Machine (M2M) communication, where devices communicate directly with each other or with a central system without human intervention.
   • The correct option is d. M2M.

5. .................... Are smart devices that uses embedded processors, sensor and communication hardware to collect and send data which is acquired from environment

   • The description perfectly matches the characteristics of IoT devices, which are essentially specialized embedded computers. Among the given options, "Computers" is the most appropriate term to describe these devices.
   • The correct option is a. Computers.
