Captcha is used to know if the user is really a human and not just a programmed robot. It would display figures which contains letters and/or numbers in which the user would identify and the robots wouldn't. That way, spammers would be prevented to spam on your website.

When it comes to integrating that on your website, Google is you best friend! So, good luck!

It is automatically generating challenge that human can pass but not the computer. Humans can read distorted text which can't be read by computers. It is used for preventing comment spam and protecting website registrations, also preventing dictionary attacks and worms/spams.

CAPTCPA is mainly used to prevent automated software (bots) from performing actions on behalf of actual humans. For example while signing up for a new email account, you will come across a CAPTCHA at the end of the sign-up form so as to ensure that the form is filled out only by a legitimate human and not by any of the automated software or a computer bot. The main goal of CAPTCHA is to put forth a test which is simple and straight forward for any human to answer but for a computer, it is almost impossible to solve.

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.

Captcha is created to stop the automated submissions. If there is no captcha, u can do more than 2000 submission per day. If u want to include it, u have to pay for that. I have no idea about that.
