CAPTCHA is the acronym for Completely Automated Public Turing test to tell Computers and Humans Apart. It is a type of test used to determine whether the user is human or not. The behind this is to prevent machines from performing tasks that should be done by real people, especially during the registration of accounts. CAPTCHA is a combination of both alphabets and numbers, and the alphabets can be in upper case or lower and at times they can be mixed.
Most times, it doesn't come very clean, you will need to look properly before you can identify all the alphabets and digits that make up the CAPTCHA. For example, you can be sent something like this AtY5sY, but it will not be arranged properly like this. You are most likely to be sent a CAPTCHA you are creating accounts like Gmail and others. The CAPTCHA will be sent so as to know whether the account is being created by a human being or machine.

CAPTCHA is also known as Completely Automated Public Turing Test. Basically, this is a type of test that will be expected to tell apart people and computers. There are different CAPTCHA examples that are being used. There are some that would require the input of different letters and numbers.
The CAPTCHA is normally used to make sure that only human users will be able to pass through and use the website. A lot of computers are unable to solve the CAPTCHA so they would not be able to continue checking out the website anymore. There are some websites that will enable CAPTCHA whenever they feel that the way that the user is behaving is a bit unusual.

CAPTCHA is an acronym for Completely Automated Public Turning test to tell Computers and Humans Apart. This term was coined by Luis von Ahn, Nicholas J. Hopper, Manuel Blum and John Langford in 2003. CAPTCHA is a challenge test used to tell whether a user is human or not.
It is used as spam detection by detecting illicit use of robot or machines to answer forms on the internet. There are different types and sizes of CAPTCHA. Some are easy to solve, and some of them are harder. Examples include standard word captcha, audio, picture identification, drag, and drop captcha, 3D captcha, math solution, and so on.
Ah, this is a good one. Captcha is a device to catch out any illicit use of robots to 'answer' forms or material on the internet and to pose as if they were real people responding.
Captcha stands for Completely Automatic Public Turing Test to Tell Computers and Humans Apart. This is an example of a clearly worded description that really does need an acronym because of its great length.
