| Every day we solve a CAPTCHA test, but only few of us are well-aware of its purpose. The World Wide Web is a favourable place where users communicate, exchange information, do business in a convenient and inexpensive manner. But at the same time it is especially favoured by spammers, hackers & online fraudsters, with loads of spam and junk mail spreading around the global net. The abbreviated term CAPTCHA is decoded as 'Completely Automated Public Turing test to tell Computers and Humans Apart'. It appeared in the year of 2000 as an anti-spam module. It is a compulsory test that World Wide Web users have to before posting an electronic mail. A CAPTCHA test comes in a number of types. Yet, the most widespread one that we usually come across is a mixture of figures & letters often crossed with a line. Letters are not typed straight. Thus, it takes a user several seconds to comprehend what a prompt box contains. Some users may find the CAPTCHA test excessive. Nevertheless, it is a necessary preventive measure to protect your mail box from spam & junk mail. Actually it is the computer that creates a test & assesses how successful a user has been in solving it. But the computer program is incapable of solving a test itself. So, if you solve a test correctly, the computer identifies you as human, because bots cannot solve a CAPTCHA. This is the way the computer identifies whether users are human or bots. Spam is known to be assaulting the Internet. Surely, there are various anti-spam modules that filter mail. However, Drupal CAPTCHA is believed to be much more efficient. Alongside the spam protection, the module secures the protection process, too. The Drupal CAPTCHA adds a compulsory test to all forms used by users or guests. As stated above, the CAPTCHA module is in great need today. So, before you opt for a CAPTCHA service provider, assure it will satisfy your needs. You can download a free trial version to view if a module suits you. Some CAPTCHA modules are compatible with a great number of programing languages.
