سوال ۱۷ کنکور ارشد مهندسی کامپیوتر ۱۴۰۲

PASSAGE 2:

A CAPTCHA prevents bots from filling out and submitting a public form on a website. A common type of CAPTCHA requires the user to type letters and/or digits from a distorted image that appears on the screen. CAPTCHAs are used in attempts to prevent automated software from performing actions, which degrade the service quality of a given system, whether due to abuse or resource expenditure. The process usually involves a computer asking a user to complete a simple test which the computer is able to grade. Since these tests are designed to be easy for a computer to generate but difficult for a computer to solve, but again easy for a human being to grade, if a correct solution is received, it can be presumed to be entered by a human. The aim of CAPTCHAs is thus to use a new technique to promote company products or websites. In CAPTCHA advertising, users typically type in brand messages instead of distorted text. In today's technology, using of CAPTCHAs are twofold: website security and advertising.
