What Is the Internet of Things (IoT)?

The Internet of Things (IoT) refers to physical objects that are connected to the internet and can:

• Collect data

• Share data

• Act on that data automatically

These “things” can be:

• Home appliances

• Wearable devices

• Vehicles

• Machines

• Sensors

IoT allows devices to communicate with each other without human involvement.

How IoT Works (Simple Explanation)

IoT works in a few basic steps:

1. Sensors collect data
   Example: A temperature sensor measures room temperature.

2. Internet connection sends data
   The data is sent through Wi-Fi, mobile networks, or Bluetooth.

3. Data processing
   Cloud servers or software analyze the data.

4. Action is taken
   A command is sent back to the device (like turning on a fan).

All this happens in seconds.

Key Components of IoT

IoT systems usually include:

• Devices/Sensors – collect information

• Connectivity – Wi-Fi, mobile data, Bluetooth

• Data processing – cloud platforms

• User interface – mobile apps or dashboards

Together, these components make IoT work smoothly.
