If you don’t know what that is, please let me save you the trouble of Googling it. It’s based on the word ‘capture’ and is an acronym for “Completely Automated Public Turing test to tell Computers and Humans Apart.”

According to Wikipedia, CAPTACHA is a challenge-response test used in computing to ensure the response is not coming from another computer. You’ve all seen it. It’s that little block of text that’s typed in by what’s assumed to be a “human” versus another computer.
