解説
問 3
Incorrectア
Groupware is business application software that supports information sharing and collaborative work within an organization, providing functions such as email, schedule sharing, bulletin boards, and workflow. It has nothing to do with the basic control of hardware and is not device-embedded software.
Incorrectイ
Shareware is a term referring to a distribution and payment model in which the user pays a fee to continue using the software after a trial period; it is not a classification based on the software's function or role. It has nothing to do with the function of controlling hardware.
- ウ
正解 ウ Firmware is correct. Firmware is software written into a device's ROM or flash memory that directly performs the basic control of the hardware. It is embedded in devices such as game consoles, home appliances, printers, and routers, and is normally not rewritten by users on a daily basis. It sits at an intermediate position between hardware and software, which fully matches the question's description of software embedded in a device that performs basic control of the hardware.
Incorrectエ
Middleware is software that sits between the OS and application software and provides common functions such as database management and communication processing. It serves as a bridge between software components and is not software embedded in a device to perform basic control of the hardware.
ここがポイント
- Firmware = software embedded in a device that performs the basic control of the hardware. It exists as an intermediate between hardware and software.
- Distinguishing the confusing -ware terms: groupware (collaborative-work support) / shareware (distribution and payment model) / middleware (intermediate layer between the OS and applications).
