What is captcha? »Its Definition and Meaning
If you've ever tried to register on a website or comment on a blog and have been asked to enter some weird words that have been all messy, you know how frustrating it can sometimes be to say a lowercase L from a number 1 or an uppercase O of a number 0.what are those crazy letters and why do we have to write them on the website to move on?
Those crazy codes are called CAPTCHA, and they are a human response test .The word is actually an acronym for: «Public fully automated Turing test to tell computers and human beings apart ».
The reasoning behind why websites implement CAPTCHA codes in their registration processes is due to spam.Those crazy letters are a way to check if the person who register or try to comment is a real human being compared to a program d e computer that tries spam the site.Yes, it's the same reason why most of us have some type of spam blocker in our email.
Junk mail is the current equivalent to junk mail, but if spammers were in charge, junk mail would not be in your mailbox.
And although it is frustrating that you are continually asked to enter tangled letters of a image , is worth it in the long term .Anyone who has ever created their own website or blog you will get a taste of what spam is like up close and personal only weeks after going online-even if that website or blog has almost no traffic.
Spammers find small websites and Quick blogs and point them out because they often don't have much security to protect them.
If a site or blog owner didn't use some kind of protection like C APTCHA against it, would be receiving dozens of spam loggers or comments a day .And that's only for small websites and personal blogs that aren't very popular.I can only imagine what popular blogs must see.
