What is CAPTCHA?

I used CAPTCHA many times in developing different Web Applications and even used in many websites but didn't know the formal name. I used to identify it as Word Verifier or code for Word Verification. Whatever! Now I learned that the formale name is CAPTCHA!

While i was looking into Online for more information on CAPTCHA see few interesting URL i got sharing with you all below:
