Smart
In short
Smart refers to a device or system that uses internet connectivity and software to perform tasks automatically or respond to user input.
In plain words
These objects can talk to each other and to you through an app. They use sensors to collect data and make decisions without you needing to do everything manually.
A simple example
A smart thermostat learns when you are at home and adjusts the heating to save energy. You can also change the temperature using your phone from the sofa.
Why it matters
It makes daily life more convenient and can help save electricity or water. It also allows people to monitor their homes or health from anywhere in the world.
Easy to mix up
Do not confuse smart devices with automated ones; a smart device requires a connection to process data, while a simple automated one just follows a basic timer.
