Introduction to Internet of Things (IoT)
The Internet of Things (IoT) is a modern technology that connects physical objects to the internet, allowing them to collect, share, and process data automatically. These objects can be everyday devices like smartphones, smartwatches, home appliances, vehicles, and industrial machines. IoT makes systems smarter, faster, and more efficient by enabling communication between devices without human intervention.
This topic is important for students because it forms the foundation for understanding smart systems, automation, and future technologies like smart cities, artificial intelligence, and connected environments.
What is Internet of Things (IoT)?
The Internet of Things refers to a network of physical devices embedded with sensors, software, and connectivity that allows them to exchange data over the internet.
Simple Meaning:
IoT is like giving everyday objects the ability to think, sense, and communicate.
Key Idea:
Devices are connected → Data is collected → Data is processed → Actions are performed
Why IoT is Important in Modern Technology
IoT plays a major role in transforming industries and daily life by making systems intelligent and automated.
