Captcha questions are security questions that you have to answer in order to post a comment on a website or login to a website or account. They are designed to filter out automated spam posts and login attempts, since computers are not able to answer these questions. They usually ask you to enter the characters shown in an image, or to type in a word shown in the image. There are lots of different captcha schemes used by different websites, but the idea is the same -- to stop automated posts and logins, without restricting normal human use of the site.

Captcha is short for “Completely Automated Public Turing Test to Tell Computers and Humans Apart”. These are little tests that folks have to solve before they can leave a comment on a website or submit a contact form or something like that. The idea is to make it difficult for a machine to solve these checks, so that it’s clear that a real person is interacting with the website. Captchas usually include little images with letters or numbers written in them, or they might ask you to type in some words that appear in a picture. They’re mostly used to prevent spam and malicious code from being posted on websites, but they can also sometimes frustrate site visitors who are trying to leave a legitimate comment or submit a form. I’m not a huge fan of captcha, I think they slow down the web experience for everyone and can be annoying to deal with. But I understand why they’re used, and I think they do help avoid some spam and hacking attempts.
