CAPTCHA's are developed in an attempt to eliminate spam from automated systems. Some sites on the internet require the use of CAPCHA's which is a combination of letters and numbers a user needs to input to allow viewing of the site.
There is a random string of texts at the end of registration. The text is called as capcha only. The capcha is helpful to prove that the person is not a bot.
A CAPTCHA is a type of challenge-response test used in computing to determine that the user is not run by a computer. The process involves one computer (a server) asking a user to complete a simple test which the computer is able to generate and grade. Because other computers are unable to solve the CAPTCHA, any user entering a correct solution is presumed to be human. A common type of CAPTCHA requires that the user type the letters of a distorted image, sometimes with the addition of an obscured sequence of letters or digits that appears on the screen.The most common CAPTCHA device is to present an image of letters slightly distorted so an optical reader cannot make them out, but the human mind still can. The human recognizes each letter and types it in in the order presented to prove he is in fact human.
The CAPTCHA code - is used by many web-sites - not just WikiAnswers. It's designed to prevent automated systems from creating accounts - since the code cannot be read by text recognition software - and thus, a response must come from a person, not a machine.
