CAD is widely used in various industries such as architecture, engineering, and manufacturing.
10.
Which of the following is NOT an example of a system?
Correct Answer
C. CD - ROM
Explanation
CD-ROM is not an example of a system because it is a storage medium rather than a complete functioning system. A computer, car engine, television, and phone are all examples of systems as they consist of multiple components working together to perform specific functions. However, a CD-ROM is simply a type of optical disc that stores data and requires a separate system, such as a computer or CD player, to read and access the data stored on it.
11.
Which operating system makes extensive use of a command line interface?
Correct Answer
B. MS DOS
Explanation
