The Internet of Things (IoT), access to real-time data, and the introduction…

Industrial revolutions are named for the core technology driving production in that period: mechanized, steam-powered production defines the first; mass production with electricity defines the second; electronics-driven automation defines the third; and the integration of cyber-physical systems, the Internet of Things (IoT), and real-time data exchange defines the fourth, commonly called Industry 4.0.

The stem names exactly this defining triad for the era in question: IoT connectivity, real-time data access, and cyber-physical systems. That combination identifies the era as Industry 4.0.

• Industrial Revolution names the broad historical shift to steam-powered mechanization, which predates IoT, real-time data networks, and cyber-physical systems entirely.

• 3rd Industrial Revolution refers to the electronics- and computer-driven automation period that came before IoT and cyber-physical-system integration became defining features.

• Manufacturing automation is only one enabling technology used within this era; on its own it does not capture the combined IoT, real-time-data, and cyber-physical-systems identity named in the stem.

Hence the era described is correctly identified as Industry 4.0.
