History of computers in pharma R&D MCQs With Answer

This quiz collection explores the historical evolution of computers and their transformative role in pharmaceutical research and development. Designed specifically for M.Pharm students studying Computer Aided Drug Development (MPH 203T), the questions cover early computing milestones, key software and databases, landmark algorithms, regulatory shifts, and the technological advances that enabled modern in silico drug discovery. Emphasis is placed on practical historical context—how mainframes, mini- and microcomputers, molecular modeling, docking, cheminformatics, high-performance and distributed computing, and electronic regulatory systems shaped workflows in medicinal chemistry, pharmacology and bioinformatics. Use these MCQs to test and deepen your understanding of how computational tools became integral to contemporary pharmaceutical R&D.
