AKTU Computer Organization and Architecture (BCS302) Question Bank with Solutions – B.Tech 2nd Year Sem 3

This question bank has been compiled by UQuest (by University Academy) to help you prepare efficiently for the BCS302 Computer Organization and Architecture semester examination (AKTU). Each of the five syllabus units contains 15 short-answer questions (2 marks) and 15 long-answer questions (7–10 marks), each with a complete, exam-ready solved answer including block/circuit diagrams, register-transfer notation and fully worked numericals (Booth's algorithm, IEEE-754, cache mapping, CLA adders and more) wherever applicable.

Understanding the Tags

• MOST IMPORTANT — Repeatedly asked across multiple AKTU examination years, or covers a core syllabus concept almost certain to be examined — prioritise these first.
• IMPORTANT — Asked in at least one recent AKTU examination, or a high-value supporting concept — cover these after the Most Important questions.

PYQ: AKTU <year(s)> — Indicates this question (or a very close variant of it) has actually appeared in the AKTU BCS302/KCS302 semester examination in the year(s) shown, compiled from official/publicly archived AKTU question papers spanning 2018–2024.

A Note on Previous-Year Questions

The PYQ year-tags in this book are compiled from publicly archived AKTU Computer Organization and Architecture (BCS302 / KCS302, formerly RCS302) question papers covering the examinations of 2018-19, 2020-21, 2021-22, 2022-23 and 2023-24. Where a question in this bank closely matches a previously-asked question, the year(s) it was asked are noted; numerical questions reuse the exact figures from the original paper wherever these could be verified, and are clearly noted as representative worked examples where a specific original data-set could not be confirmed. Question wording has, in places, been rephrased slightly for clarity and consistency of style — always cross-check against your own institute's latest circulars for any last-minute syllabus changes.

Suggested Preparation Strategy

• Start each unit with all questions marked ★ MOST IMPORTANT — these give the highest return on revision time.
• Attempt every numerical / trace question (Booth's algorithm, IEEE-754, cache mapping, CLA adder, page-replacement) by hand at least once before checking the worked solution.
• Redraw every diagram (bus architecture, pipeline timing chart, cache/memory address formats, DMA and interrupt block diagrams) from memory — diagram-based recall is heavily rewarded in AKTU answer sheets.
• Revise the ☆ IMPORTANT questions next, followed by the remaining questions for full syllabus coverage.
• Use the Detailed Syllabus section to confirm no topic has been missed before the exam.
