Acronym: Completely Automated Public Turing test to Tell Computers and Humans Apart.

Tests that are easy for a human to pass, but difficult for a computer (thus preventing things like automated signups).
Ever see those registration forms that show a distorted picture and asks you to identify the word in it? That's a CAPTCHA.

A CAPTCHA is a test to see if you are a robot while signing in to sights, posting stuff, etc. For some reason, Internet workers decided that just because a robot can make accounts, post stuff and all that doesn't mean it can tap a βœ… on a box or select all the pictures with traffic lights and all that stuff. No, that's impossible but making users and everything isn't. Of course.
-Damn it, I have to do another CAPTCHA
-But that's so easy! Robots could do it.
-Shh,they might hear us and make it an essay about feelings

-But I have none!
-At least you know what traffic lights are
