In this episode I discuss the Fourth Industrial Revolution (4IR), with my guest Dr. Rajeeva Kumar. In part 1 of this two-part series, we cover what 4IR is, how it compares to the previous industrial revolutions, and why it matters to users of Industrial Control Systems. We discuss the different elements of 4IR such as low cost sensors, computing power, cloud computing, connectivity and network protocols, data analytics, edge computing, and more.
