If you’re familiar with web design, you probably heard of CAPTCHA and that it’s used to reduce spam on online forms. As the capital letters denote, it does actually stand for something. That is, “completely automated public Turing test to tell computers and humans apart.” Yes, it seems “test to tell” is getting represented as a whole by the one “T” and the “and” is not represented by a letter. It does clearly describe what CAPTCHA is. Usually this program consists of a random generated string of letters and numbers, with various coloring, styling, and added noise that the user must enter in a text field to submit the form successfully. An example is on our website contact form.
Not chess.
