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.
CAP code
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.
The text you type on registration screen is capcha. The capcha text is very important in a form. It disables the automatic filling by a bot.
