The Fourth Industrial Revolution, or Industry 4.0, refers to the change in technology, industries, and processes in the 21st century due to increased connectivity and automation in all sectors. To understand Industry 4.0, it’s important that we take a brief look at the first three revolutions. The first industrial revolution kicked off with the introduction of mechanization, water power, and steam power. The second industrial revolution revolved around mass production through assembly lines with electricity being the key power source. Then, the third industrial revolution incorporated the use of electronics, IT systems, and automation. And finally, the fourth industrial revolution is further pushing the envelope by integrating the internet, cyber-physical systems, cloud computing, artificial intelligence, etc. into the fold.
