Computer Classification by Size — MCQ Practice Questions

Computers come in vastly different sizes, from the smartphone in your pocket to the room-sized supercomputers used by space agencies and defense organizations. The Computer Classification by Size topic tests your ability to identify, compare, and apply knowledge of four fundamental computer categories that appear regularly in government recruitment exams. Microcomputers include personal computers, laptops, tablets, and smartphones — the most widely used category. Minicomputers (also called mid-range servers) bridge the gap between personal and enterprise computing. Mainframe computers power large-scale transaction processing for banks, insurance companies, and government agencies — handling thousands of simultaneous users with near-perfect reliability. Supercomputers, measured in FLOPS (Floating-Point Operations Per Second), represent the pinnacle of computational power and are deployed in weather forecasting, nuclear research, and AI model training. With 50 questions spread across three quiz sets, this topic provides exhaustive coverage that ensures no aspect of this classification goes unpracticed. Key Subtopics: • Microcomputer: types, examples, applications • Minicomputer: characteristics and use cases • Mainframe computers: enterprise applications • Supercomputers: FLOPS, examples (Param, Cray) • Comparison across all four categories
