It is over for the time,'' answered Rebecca; ``our friends strengthen themselves within the outwork which they have mastered, and it affords them so good a shelter from the foemen's shot, that the garrison only bestow a few bolts on it from interval to interval, as if rather to disquiet than effectually to injure them.
PnP. 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.
pnp in Technology Expand. 1. A type of bipolar transistor consisting of a layer of N-doped semiconductor (the base) between two P-doped layers (the collector and emitter). PNP transistors are commonly operated with the emitter at ground and the collector at a negative voltage. In the 1960s, the germanium PNP transistor was the cheapest and best for use at ordinary temperatures. The leakage current from collector to base in this type of device is larger than for the silicon transistor, and also varies more with temperature.
