Plug and Play stands as a pun for putting in and playing, so to speak, one has almost no work with it!
Represents the simplicity in dealing with the peripheral devices and other devices (printers, plotters , mouse, keyboard, scanner, ...) and to communicate with them and to be able to use them. So just plug in and you can use them.
But this is not quite so, despite great efforts, even the creator of the term (Microsoft) is not always Plug & Play even under the latest operating system. But connecting and despairing.
Especially printers and scanners are the biggest problem here.
But the standard plug and play feature is in place and pretty mature, except for a few exceptions. But 100% there is almost as good as nowhere.
The Plug and Play set is an Intel-introduced specification that allows a computer to automatically discover and configure a device, and if necessary, the operating system can install the appropriate device driver.
