If you work at a website design company (as your signature would suggest) it is hard to believe you wouldn't know what captcha was, but...Quote:

It works to stop spammers (at least machines) but it can be very frustrating to us humans that don't see so well. :)
In a CAPTCHA test (an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart," also sometimes spelled in lowercase), an image of letters is dynamically generated. The letters, because they're part of an image and not text (e.g. text that you could cut and paste), are difficult for a spambot or other computer program to read. Yet, a person has little trouble reading the letters in a captcha image.Using a captcha test on a website is a great way to ensure, for instance, that a person and not a spambot is filling out a web form. Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm the form's purpose.

Hi........,
I my opinion CAPTCHA is a code which is used to stop automated computer Spam robots from filling out forms, harvesting email addresses, and then sending out countless Spam emails. And it is best one.
CAPTCHA is a type of challenge-response test used in computing to ensure that the response is not generated by a computer. The process usually 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. Thus, it is sometimes described as a reverse Turing test, because it is administered by a machine and targeted to a human, in contrast to the standard Turing test that is typically administered by a human and targeted to a machine.
CAPTCHA stands for Completely Automated public turing Test To Tell Computers and Humans Apart. It is a program that can generate and grade tests that humans can pass but current computer programs cannot.
in simple word CAPTCHA can stop Auto 0r Computrised submitter of spam to your site, it verify a human visitor on your site.
Here is a helpful blog that I have found that helped me that sums it up nicely:

having captcha in your side is a pretty good way of fending off spammers, especially if you do not want to do the hassle of finding hem one by one. most forums and sites nowadays that offer membership have captcha to prevent spamming and site overload by bots, it's a pretty good investment for a decent site
I believe that first of all you need to do the search for it. As usual that is paid
So are you ready to pay for the captcha?

captcha test on a website is a great way to ensure, for instance, that a person and not a spambot is filling out a web form. Also, a captcha can make it difficult for a person to continuously resubmit form information and overwhelm the form's purpose.
A CAPTCHA (Completely Automated Public Turing Test to tell Computers and Humans Apart) is a challenge-response system test designed to differentiate humans from automated programs. A CAPTCHA differentiates between human and bot by setting some task that is easy for most humans to perform but is more difficult and time-consuming for current bots to complete.
CAPTCHAs are often used to stop bots and other automated programs from using blogs (see splog) to affect search engine rankings, signing up for e-mail accounts to send out spam or take part in on-line polls.

Hi,
Captcha is security code you needed to enter while filling any forms to ensure that the form is filled by a human not by robot. You can get Captcha for your site from the internet. There are many free Captcha sites.
In a CAPTCHA test an image of letters is dynamically generated. The letters, because they're part of an image and not text are difficult for a spambot or other computer program to read. Yet, a person has little trouble reading the letters in a captcha image.

A Captcha is a program that can generate and grade tests that humans can pass but current computer programs cannot pass.These were created in response to bots that automatically fill in Web forms as if they were individual users. Bots are used to overload opinion polls, steal passwords and, most popular, to register thousands of free e-mail accounts to be used for sending spam.
