Before we had modern computers to easily sort data, data was organized on punch cards that tabulated data and often had to be sorted in order to properly analyze things like school grades of even accounts payable and receivable. It’s fascinating to watch out computing worked mechanically and how amazing the machines were for the time and how limited that they were. This is a short periscope film so if you’re curious about how punch cards worked in an easy way, this is the video for you! It’s pretty amazing how far we’ve come considering they are working on Quantum Computers that can process data in ways that we are only beginning to understand.
