Uses and meaning of CAPTCHA
Hi,
Hi,
Hi dear,
It’s a very good question that's why we use captcha. But first of all, I would explain to you the term CAPTCHA. CAPTCHA is a short form of: 'Completely' 'Automated' 'Public' 'Turing-test to tell' 'Computers' and 'Humans' 'Apart'. CAPTCHA is a type of "Challenging-response Test" which separates the humans with computers. Captcha's are used to stop automated softwares from executing tasks which degrades the quality of a service, such as spamming , harvesting email addresses, filling out the forms, fake registrations and much more.
A server computer generates a simple test asking a user to solve it. The user types the letters or digits from a distorted image. The following image explains it in a better way.
It means Captchas are very important for the websites having forms. I am making a contact us page in my blog can I add captcha to it?
Yes sure, Captcha codes are provided for free by many websites and can be embedded easily in forms.
I embedded a captcha in my blog. It’s amazing. Well. Thanks for the help.
Hello Jennifer,
Wow, I didn't know that's what captcha means and how it works. I did the captcha job before without knowing how it works, your explanation about it is a valuable information that helps me to better understand it. Just want to say good job in explaining it in details. I can definitely say to myself that I am well informed now about Captcha. Kudos to you.
