What is CAPTCHA?
CAPTCHA is a type of challenge-response test used in computing to determine whether the user is human. CAPTCHA helps protect you from spam by asking you to complete a simple test that proves you are human and not a computer. A common type of CAPTCHA requires that the user type the letters or digits of a distorted image that appears on the screen.
