DefinitionPlug and Play (プラグアンドプレイ) is a mechanism in which, once you connect a peripheral device, the OS automatically recognizes it and takes care of installing and configuring the matching device driver.
ExplanationIt exists to save you the trouble of finding and installing drivers by hand, and connection standards such as USB support it. Connecting or removing a device while the power stays on is called hot plugging (ホットプラグ), a feature concerned with when you may attach or detach.
AnalogyIt is like a thoughtful front desk where staff size up your preferences the moment you walk in and set up your seat and tools for you.
Memory hookPlug (insert) plus play (use) reads as "plug it in and use it right away."
