解説
問 58
- ア
正解 A device driver is software that makes a peripheral device usable from the OS; it is normally installed per device and stored on the HDD. When the HDD is initialized and the OS is reinstalled, all data on the disk is erased, so drivers not included in the OS by default (those the user installed separately afterward) are lost. Therefore they must be reinstalled, so choice ア is appropriate.
Incorrectイ
A device driver is meant to control a peripheral device (hardware) and is independent of installing application software. Even if you install a new app, no reinstallation is needed as long as the driver for that device is already installed. The claim that all drivers used by that software must be reinstalled is wrong.
Incorrectウ
When a device driver is no longer needed, the user can delete (uninstall) it through the OS device manager and the like. The claim that once installed it cannot be deleted by the user is contrary to fact.
Incorrectエ
Because a printer driver controls the device differently for each manufacturer and model, in principle a driver matching the printer model in use is required. The claim that installing just one lets all printers be used is wrong, and unsupported models will not work correctly.
ここがポイント
- A device driver is software that makes a peripheral device usable from the OS; it is specific to each device (model) and stored on the HDD.
- Reinstalling the OS (initializing the HDD) erases the data on the disk, so drivers installed separately outside the OS defaults must be reinstalled. Deleting a driver can be done by the user.
