Q1. Which of the following is not a class or category of computers?
A Micro Computer
B Mini Computer
C Mainframe Computer
D Parallel Computer Correct
Explanation
Traditional classification of computers by size and capacity includes micro computers, mini computers and mainframe computers. These are standard categories taught in basic computer awareness. Parallel computer refers more to a processing approach or architecture in which multiple processors work together, rather than the usual class or category in this basic classification. Therefore, micro, mini and mainframe fit the printed category list, while parallel computer is the odd entry asked by the question.
