PnP is an ability of a computer to detect and configure hardware automatically, without requiring the user to physically configure the hardware with jumpers or dip switches. Plug and play was introduced on IBM compatible computers with the release of Microsoft Windows 95. Apple Macintosh computers have always supported the ability to automatically detect and install hardware.

3. PNP is a type of bipolar transistor.
