解説
問 14
Incorrectア
A circuit that converts analog signals into digital signals describes an A/D converter (ADC), which has nothing to do with CAD.
- イ
正解 CAD stands for Computer Aided Design, a technology that uses a computer to assist with design work for buildings, machines, industrial products, and the like. Designers can create and modify drawings on screen, and dimension changes and reuse become easy, improving the efficiency and accuracy of design. Choice イ, using a computer to design buildings, industrial products, and the like, matches this definition, so it is the correct answer.
Incorrectウ
An image sensor that converts light into electrical signals describes devices such as CCD or CMOS image sensors, which have nothing to do with CAD.
Incorrectエ
Combining data such as text, images, and audio to create a single piece of content describes multimedia authoring, which differs from CAD's design assistance.
ここがポイント
- CAD (Computer Aided Design) is a technology that uses a computer to assist with design, streamlining the creation, modification, and reuse of design drawings.
- Be careful not to confuse the definition with similar terms (A/D conversion, image sensor, multimedia authoring); remember the distinct role of each term.
