PnP may refer to any of the following:
1. Short for Plug-and-Play. 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.
For Plug-and-Play to operate properly on IBM compatible computers the computer must have:
- BIOS supporting Plug-and-Play.
- Windows 95 or later or another operating systems supporting PnP.
- Peripheral with PnP support.
Tip: Today, all new computers have PnP capabilities.
2. Slang for Plug-and-Pray, this term was commonly used when Plug-and-Play was first introduced because it was notorious for not working. Many jokingly thought it took a prayer before any devices would work using PnP.
3. PNP is a type of bipolar transistor.
4. Abbreviation for Party and Play, PNP is shorthand used in online chat, ads, and communities of letting others know you want to meet to do drugs and play (sexual encounters).
