What is the Internet of Things (IoT)?

The Internet of Things (IoT) is one of the most important technologies transforming the way we live, work, and interact with devices. IoT connects everyday objects to the internet, allowing them to collect data, communicate with each other, and perform intelligent actions automatically.

From smart homes and wearable devices to smart agriculture and industrial automation, IoT is creating a more connected and efficient world.

For students, learning IoT provides an opportunity to understand how sensors, electronics, programming, and communication technologies work together to build smart solutions.

What is IoT?

The Internet of Things refers to a network of physical devices connected to the internet that can collect, exchange, and process information.

These devices can include:

• Sensors
