ITPEC IP April 2023 Question 13

Which of the following is a plug and play function?

a)The automatic playback that is performed when a DVD is insertedb)The automatic installation of a device driver that supports a newly connected peripheral device to the PCc)The automatic fault diagnosis for a connected peripheral deviced)The automatic periodic virus scan of a disk drive

Explanation

Automatic installation of the device driver for a newly connected peripheral — Plug and Play lets the OS recognise a device and set it up without manual configuration.

When a peripheral is connected, the OS identifies the device, allocates the resources it needs, and installs and configures the matching device driver, so the device can be used right away. Connecting a USB mouse or printer is the everyday example.

Answer (b)

Why not others:

•(a) — playing a DVD automatically on insertion is AutoPlay (autorun), which acts on the content of the media, not on setting up a device
•(c) — diagnosing faults in a connected device is a self-diagnosis or monitoring function
•(d) — a periodic virus scan of a disk is scheduled scanning by antivirus software

Key rule: Plug and Play means automatic recognition and driver setup of hardware as it is connected; what then happens to the media or files on it is a different function.
