Plug and Play (PnP) is a system capability in which the operating system recognises hardware when it is connected, identifies it, loads a suitable driver and assigns the resources it needs, without the user editing settings by hand.
Why it matters
Before PnP, adding a sound card or modem often meant setting jumpers and resolving resource conflicts manually. Today, USB and Bluetooth devices announce what they are, so a mouse, keyboard or flash drive usually works within seconds. It lowers the barrier to using hardware, though specialised devices may still need a vendor driver or software.
Example
When you plug in a USB webcam, the device reports its vendor and product ID. Windows finds a matching built-in class driver, installs it and shows the camera in apps. You can check what was detected on Linux with:
lsusbIf no driver matches, the device may appear as "Unknown device" in Device Manager.
Common mistakes
- Assuming every device is fully supported; basic functions may work while extra features need the vendor software.
- Downloading drivers from unofficial sites after a failed detection.
- Confusing plug and play with hot-swapping, which is safe removal while running.
