What is flag in computer terminology?

Answer 1

Flagging can mean a couple different things. In general it always means "to mark". In Microsoft Outlook you can flag an E-mail you've recieved. In this case it means you're marking it for a follow-up. On community websites such as wikipedia answers, Craigslist, etc. flagging might be a bad thing. People can be flagged for spam, inappropriate content, or not following the rules of the website. In this case flagging usually results in a post being taken down or made unviewable. I hope this information has helped you!
