Which of the following group of statements in the context of Information Technology (IT) is correct?
A. Mouse, Keyboard, and Plotter are all input devices.
B. Unix, Windows, and Linux are all operating systems.
C. Register, Cache Memory, and Hard Disk are all memory modules.
D. Monitor, Printer, and Scanner are all output devices.
Answer and explanation
Correct answer D
Statement B is correct, as Unix, Windows and Linux are all operating systems. Statement C is acceptable, since registers, cache and the hard disk are all storage elements in the memory hierarchy from fastest to slowest. Statement A is wrong because a plotter is an output device and statement D is wrong because a scanner is an input device, so only B and C are correct.
