What is CAPTCHA?

CAPTCHA is an acronym for "Completely Automated Public Turing Test to Tell Computers and Humans Apart". As the name suggests, it is a test that determines the probability of the solver being a human. As defined on the CAPTCHA home page at the Carnegie Melon University School of Computer Science's Web site:

CAPTCHA is a program that can generate and grade tests that:

Most human users can pass
Current computer programs can't pass
