問 64
Incorrectア
The automatic playback when a DVD-Video is inserted is the “autorun (automatic playback)” feature, which automatically launches an application triggered by inserting media; this is a different feature from Plug and Play, which installs peripheral device drivers.
- イ
正解 Plug and Play is a feature by which, simply by connecting a peripheral device, the OS automatically detects the device and automatically installs and configures the corresponding device driver, bringing it into a usable state. It saves the user the trouble of manually finding and setting up drivers. Therefore, choice イ, which describes “installing into the OS the device driver corresponding to a newly connected peripheral device,” is correct.
Incorrectウ
Fault diagnosis of already-connected peripheral devices is handled by diagnostic tools or the OS’s fault-detection feature. Plug and Play is a feature that recognizes devices and configures drivers; it does not diagnose faults.
Incorrectエ
Periodic virus scanning of disk drives is the role of antivirus software. It is unrelated to Plug and Play, which performs automatic setup when a device is connected.
- Plug and Play = a feature by which, once a peripheral device is connected, the OS automatically detects it and automates the installation and configuration of the corresponding device driver.
- Autorun (automatic playback), fault diagnosis, and virus scanning are each separate features and must not be confused.
