The captcha determines whether an online request or submission is made by a human or a computer. This way it protects your site's forms (registration, login etc) against bots trying to fill them in.
The "I'm not a robot" Checkbox requires the user to click a checkbox indicating the user is not a robot. This will either pass the user immediately (with No CAPTCHA) or challenge them to validate whether or not they are human. This is the simplest option to integrate with and only requires two lines of HTML to render the checkbox.
