Smart devices, we can simply say this as a talkative device – means if any electronic device able to communicate with other devices via wireless protocols such as Bluetooth, Near field communication, Infra-red, WiFi etc then those device are said to be smart devices.
Here communication between the devices means – transfer the data between two devices. For example Using mobile phone we are controlling refrigerator by sending data/commands via wireless network to set the cooling level (very high,medium,normal,low) in refrigerator whereas refrigerator will send the data to mobile such amount of ice creams, chocolate, vegetable’s, fruits and so on in the fridge. So both are communicating each other intelligently. So we can say refrigerator and mobile phone are smart device.
