As organizations face increasing pressure to reduce their environmental impact, sustainable IT practices have become a strategic priority. While mainframes have long been known as the workhorse of enterprise computing, quietly powering critical applications behind the scenes, it’s probably less well-known that they have evolved to support high-performance computing with reduced power consumption and environmental footprint. 

Our quiz this week is based on the themes that Planet Mainframe’s editor, Amanda Hendley, writes about in her article, “Sustainable IT and the Role of Mainframes in a Greener Future.” It covers the principles of sustainable IT, some misconceptions surrounding common technologies, and the innovations in mainframe computing that are helping companies meet both their operational and environmental goals.

Try our quiz to see how much you know, then check out the article!
