The abbreviation CAPTCHA sounds a bit strange. Nonetheless, we deal with it nearly every day. The Internet is a lovely place where users communicate, get information, do business in a convenient and cheap manner. But at the same time it is especially favoured by spammers, hackers & on-line fraudsters, with megabytes of spam & junk mail spreading around the global net. When decoding the IT term CAPTCHA, you will get 'Completely Automated Public Turing test to tell Computers & Humans Apart'. It emerged in the year of 2000 as protection software. It is an obligatory test that users have to before sending an e-mail. There exist a number of types of a CAPTCHA. Nevertheless, the most widespread one which we commonly come across is a mixture of figures & letters frequently crossed with a line. Characters are typed in several directions. Therefore, it takes a user several seconds to understand what is typed in a prompt box. Some World Wide Web users will find the CAPTCHA test excessive. Nevertheless, it is a crucial preventive measure to ensure any spam or junk mail will not enter your mail box. In fact it is the computer that creates a test and assesses if a user has succeded in solving it. But the computer is unable to solve a test itself. So, if you have passed an obligatory test successfully, the computer will accept you as human, as bots cannot solve a CAPTCHA. This is the way the computer identifies whether users are human or bots. It is known that spam heavily assaults the World Wide Web. In general, there are a number of anti-spam modules that filter mail. Nonetheless, Drupal CAPTCHA is believed to be far efficient. Along with the spam protection, the module secures the protection process, too. The Drupal CAPTCHA installs a mandatory test to be solved each time when users or guests are going to submit any form. As stated above, the CAPTCHA module is in great demand in the technologically advanced era we live in. So, before you select a CAPTCHA service provider, make sure it will satisfy your requirements. You can download a free trial version to see if a protection module suits you. Some CAPTCHA modules are well-compatible with a number of programing languages. Do also ensure that your service provider will guarantee an emergency server in an isolated network to maintain an unstoppable running of the sotfware, if any problems come up.
