Computer Systems Evaluation: Binary, Data Representation & Hardware

A 50-question HOTS-based interactive evaluation quiz covering Data Representation, Bits/Bytes/Binary Number System, Binary Place Values & Decimal-Binary Conversion, Input-Process-Output-Storage (IPOS) & Von Neumann Architecture, and core Hardware components (Motherboard, CPU, RAM, ROM, SSD, HDD, Expansion Cards). Difficulty is balanced across 15 easy, 20 medium, and 15 hard questions, using 8 varied formats — true/false, single-choice, multiple-answer, checklist, short answer, ordering, matching, and categorizing. Participants enter their name (displayed throughout) and are timed live from start to finish. The tool also enforces exam integrity by detecting when the browser window is shrunk below 240px or loses focus (e.g. switching tabs), showing a non-dismissable warning until the participant returns. Results include a name/score summary, breakdowns by topic and difficulty, and a full scrollable review of every question with the participant's answer, the correct answer, and the reasoning behind it.
