解説
問 83
- ア
正解 A device driver is dedicated software that lets the OS correctly recognize, control, and operate peripheral devices such as printers, mice, keyboards, and external disks. Because each device has different specifications, the driver acts as a bridge that conveys the device-specific control method to the OS. Choice ア, ‘Software for controlling and operating peripheral devices connected to a PC’, is exactly this definition, so it is the correct answer.
Incorrectイ
‘Software that starts immediately after power-on and enables basic input/output to devices such as the hard disk and keyboard before the OS runs’ describes the BIOS (Basic Input/Output System), not a device driver.
Incorrectウ
‘Software embedded into a web browser in order to display pages that contain video’ describes a plug-in (add-on) that extends the browser’s functionality, which is different from a device driver that controls peripheral devices.
Incorrectエ
‘Software that combines multiple files into a single file, or restores the combined file back to the originals’ describes an archiver (file-archiving/compression software), which has nothing to do with a device driver.
ここがポイント
- Grasp the definition of a device driver: device-specific dedicated software that lets the OS control and operate peripheral devices.
- Distinguish the differing roles of easily confused similar software: BIOS = basic input/output before the OS starts, plug-in = extending browser functionality, archiver = file compression and combining.
