                                   WHAT IS DATA ENTERY WORK?



A CAPTCHA is A  online typing test that is easy for humans  but difficult for ROBOTIC  software programs. The purpose of a CAPTCHA is to discourage hackers and spammers from using auto-filling software programs at that web page. 
SO TYPING OF CAPTCHA IS CALLED DATA ENTRY WORK IN ONLINE JOB WORLD.
 
Why Are CAPTCHAs Necessary FOR WEBSITES?
 

CAPTCHAs are used to deter hackers from abusing online services. Specifically: hackers and spammers will undertake unethical online activities, like:
  • Swaying an online poll by robotically submitting hundreds of false responses.
  • Brute-force opening someone's online account by repeatedly attempting different passwords.
  • Signing up for hundreds of free email accounts.
  • Spamming blogs and news stories with dozens of bogus comments and search engine links.
  • Scraping (copying) people's email addresses from web pages, to use them later in spam attacks.
  • Falsifying torrent seed counts and positive feedback in order to lure people into downloading a trojan payload.

                How Do CAPTCHAs Work?

CAPTCHAs work by asking you to type a phrase that a robot would be hard-pressed to read. Commonly, these CAPTCHA phrases are .gif pictures of scrambled words, but can also be .mp3 voice recordings. These pictures and recordings are very hard for conventional software programs to understand, and hence, robots are usually unable to type the phrase in response to the picture or recording.
