22. Which of the following accurately defines the concept of Modularization?
[A] A program where the instructions are modules.
[B] A technique in which the software is divided into various distinct modules.
[C] A module being an independent software component.
[D] A method where software is evolved through natural selection.
Show Answer
Correct Answer: B [A technique in which the software is divided into various distinct modules.]

28. Which of the following device is used to convert the native data into signal?
[A] OCR
[B] Modem
[C] Printer
[D] Monitor
Show Answer
Correct Answer: B [Modem]

29. Which of the following noise may occur when signals at different frequencies share the same transmission medium?
[A] White noise
[B] Intermodulation noise
[C] Cross talk
[D] Impulse noise
Show Answer
Correct Answer: B [Intermodulation noise]
