解説
問 93
- ア
正解 Blank a is “what is required to connect and use a new peripheral,” so it takes “device driver,” the software the OS uses to control that device. Blank b is “the function that, if supported, automatically installs the device driver simply by connecting,” so it takes “Plug and Play,” which automatically detects and configures the device. Therefore the combination a = device driver, b = Plug and Play, which is choice ア, is the correct answer.
Incorrectイ
a is device driver, which is correct; but b, “plug-in,” is an extension program that adds functions to application software afterward, not a function that automatically recognizes a peripheral on connection and installs its driver, so it is wrong.
Incorrectウ
b, Plug and Play, is correct; but a, “malware,” is a general term for malicious software intended to perform unauthorized actions, not something installed in order to use a peripheral, so it is wrong.
Incorrectエ
a, “malware,” is malicious software and not something needed to use a device, and b, “plug-in,” is also an app extension function, not a function that automatically installs a driver, so both a and b are wrong.
ここがポイント
- A device driver is the software the OS needs to control and use a peripheral.
- Plug and Play is a function that, upon connecting a peripheral, automatically detects it and configures and installs the device driver; it is different from a plug-in that extends an application.
