解説
問 16
Incorrectア
“Using computers to conduct education” describes computer-aided instruction such as CAI (Computer Aided Instruction) or CBT (Computer Based Training), which is different from CAD that performs design, so it is incorrect.
Incorrectイ
“Using computers to perform manufacturing operations” describes CAM (Computer Aided Manufacturing). It handles the process of controlling machine tools based on the design data created with CAD, but its role differs from CAD, which performs the design itself, so it is incorrect.
- ウ
正解 CAD stands for “Computer Aided Design,” a system that uses computers to design and draft products and the like. Because drawings can be created, modified, and dimensioned efficiently on a computer, it is used across a wide range of fields such as machinery, architecture, and electronic circuits. Therefore, choice ウ, which states “using computers to perform design and drafting,” is correct.
Incorrectエ
“Using computers to perform the design, development, and maintenance of software” describes CASE (Computer Aided Software Engineering). Its target is software development, a different field from CAD, which deals with product design and drafting, so it is incorrect.
ここがポイント
- CAD = Computer Aided Design, a system for performing design and drafting on a computer.
- Distinguish easily confused related acronyms: CAM = manufacturing support, CAI/CBT = education support, CASE = software development support.
