This phrase refers to networked infrastructures that interconnect physical objects and allow for the management of the data they generate. A typical example of IoT is a home energy monitor connected to an app on mobile phone, or a voice-activated system such as Alexa or Google Home that allows the user to play music or control the lights just by speaking a command.
