Why am I asked to enter this code?
Why am I asked to enter this code? You must have asked this question yourself some time or the other. The code is to just confirm that you are human and not any automated program or spam. Yes, this code will keep spammers away from submitting your web form; it will protect your forum, blog, guest book, etc…
Technically this concept is called captcha (A CAPTCHA is a type of challenge-response test used
in computing to ensure that the response is not generated by a computer). Ok this is all we can imagine by seeing that code image or questions like 2+2=? OR is fire Hot or Cold? 
The reason behind why I took this topic is: We all will agree to fight against spam and we cooperate for that. But here people are taking this too serious and keeping multiple code Images to enter before submitting or registering. Today one of my friends tried to register to Twitter.com and failed 7 times to satisfy that CAPTCHA code. He called me and asked hey Lax is this twitter working or down. We can’t blame him because after seeing that screenshot sent by him even you will feel the same.
Initially sites used to place single word to enter, but recently they advanced it to 2 words like as twitter asking. See the image above asked by Twitter. Hope this won’t advance more in future.

What really bugs me is when they put captchyas on login forms with letters that are unreadable. As far as I know there’s no bot or script out there that can analyze the letters on a jpg File so why Do they even bother bluring and jumbling up the letters so much?
Some times really too hectic to deal with registration forms….faily atleast twice.
Letter are laid one on one and unable to read with good eye sight also…don’t about ppl with sight and blur eyes….
Anyway good topic to choose and can i take this to my blog.

Really this sucks man..
Webmasters need to think about this..
I hate captcha code.
SOmetimes it’s really annoying to those who are really honest!
I hope it won’t advance to mathematical questions like, “what is the square root of 100?”, or “What is the formula that Einstein proved to compute the Energy?”
