Which phenomenon describes the OS automatically configuring a device after connecting it?

• A. Plug and play
• B. Hot swapping
• C. Firmware update
• D. System boot

Answer: (A)

Plug and play is the capability where the operating system automatically recognizes a newly connected device, loads the appropriate driver, and configures the device so it works right away with minimal user involvement. When you plug in something like a USB printer, the system detects it, assigns the necessary resources, and makes it ready to use without you manually installing drivers or tweaking settings. Hot swapping refers to adding or removing devices while the computer is on, which is a related hardware capability but not the automatic configuration process itself. A firmware update is about updating the device’s internal software, not about configuring it for use after connection. System boot is simply the process of starting the operating system from powered-down state.
