What's Captcha?

From Gizmodo:"You've probably seen website sign-up forms with a graphic of some crazy-looking twisted alphanumeric characters that you're asked to type into a form. That's to ensure that an actual human being has to do the signing up. It's called text Captcha (Completely Automated Public Turing test to tell Computers and Humans Apart)."
