A standard for add-in hardware that requires it to identify itself on demand (see: hot plugging). Most computer systems are now designed to be plug-and-play, so that you can buy it, bring it home, plug it in, and start playing. This makes it easier for people who consider themselves computer illiterate to use a computer, because they don't need to install devices or configure drivers-it does most of the work for you. There's also something known as "plug-and-print," a behind-the-screens technology that improves the way printers and computers communicate.
Slang usage refers to a new employee who doesn't need training. For example, "The new girl is right on; she's totally plug-and-play."
