CAPTCHA – a word you’ve probably never heard but I bet you know what it is! Find out on today’s #whatiswednesday.
A CAPTCHA is the annoying twisted words that you must enter on a website before submitting a form. Need to post an ad on Craigslist? You will encounter a CAPTCHA. Want to comment on an article or blog post? Bam! There is a CAPTCHA.
So why do we have them? They are more then just a way for web developers to frustrate you, they were invented to block spam bots from posting on websites. As hard as it is for you to read those characters, these little bots have an even tougher time, so if the CAPTCHA field is filled in correctly, chances are there is a living, breathing person submitting the form. It’s the best way to filter out hundreds of spam submissions, which will start happening almost immediately after the form on your website is published.
For those wondering, CAPTCHA stands for “Completely Automated Public Turing test to tell Computers and Humans Apart”. However, if you say that to your web developer, he will look at you like you are referring to some alien technology, so stick with sounding out the acronym.
