1) What does immelt mean by the “digitization of the industrial world” and “the industrial internet”?What are the four central elements of the industrial internet?Sensors produce data; cloud computing collects the data; analytic software processes the data; theresults are sold to business customers as a service. Sensors capture data off of machines; the data is sent over the Internet and collected by cloudcomputers; the data is analyzed by software apps, and is used to monitor machine performance for thepurpose of optimizing the performance of industrial machines. The results of this analysis, along withaccess to the data, and the GE Predix computing platform are sold to customers as a service.

(1) fire extended humans’ geographical boundaries by allowing them to travel into regions that were previously too cold to explore. (2) it also kept predators away, allowing early humans to sleep securely. (3) fire, in fact, has been a significant factor in human development and progress in many ways.
