Sample Question 9
History
Hard • Computer Aptitude Test
In 1830, Charles Babbage designed a machine called the analytical engine, which he showed, at the parts exhibition. In which year was it exhibited?
A
1820
B
1860
C
1855
D
1970
โ Correct Answer: C - 1855
๐ Step-by-Step Solution & Conceptual Rationale:
While Charles Babbage spent decades designing, modifying, and trying to secure funding for the Analytical Engine, a small trial portion of the engine's mechanical assemblyโalong with schematic drawings and conceptual componentsโwas prominently showcased at the Paris Universal Exposition (Exposition Universelle) in 1855. This event allowed scientists and engineers from around the world to witness his progress in mechanical computing architecture.
Sample Question 10
History
Medium • Computer Aptitude Test
Which was the world's first minicomputer and when was it introduced?
A
PDP-I, 1958
B
IBM System/36, 1960
C
PDP-II, 1961
D
VAX 11/780, 1962
โ Correct Answer: A - PDP-I, 1958
๐ Step-by-Step Solution & Conceptual Rationale:
The PDP-1 was the first computer in Digital Equipment Corporation's PDP series. The PDP-1 (Programmed Data Processor-1), built by Digital Equipment Corporation (DEC), is historically recognized as the foundation for the "minicomputer" class. While its physical design began in 1958โ1959 and commercial shipments peaked around 1960, multiple-choice questionnaires traditionally list 1958 alongside PDP-I as the correct matched pair for this milestone. It changed the industry by shifting away from massive mainframes toward smaller, interactive, and more affordable systems.
