Computer Organization and Architecture Important Questions for AKTU Exams
These are the Computer Organization and Architecture (COA) questions that AKTU has asked most often, compiled from previous-year papers for semester 4 B.Tech CSE and IT students. This is not a guess-paper and it is not a shortcut around the syllabus — it is a record of what the examiner has actually kept coming back to.

computer organization and architecture study guide
The topics below account for a large share of the marks in most past papers:
• instruction cycle, instruction formats, and addressing modes • Booth's algorithm and restoring or non-restoring division, traced step by step • cache mapping techniques, with direct, associative, and set-associative comparison • pipelining, pipeline hazards, and speedup calculation • hardwired versus microprogrammed control unit design • memory hierarchy, virtual memory, and page replacement
Booth's algorithm and cache mapping numericals are the highest-value items in this paper. Both are fully mechanical, both repeat almost every year, and both are commonly left unpractised because they look tedious.
Use this list to sequence your revision rather than to narrow it. Start with the repeated topics, confirm you can answer each one completely under time pressure, and only then move outward to the remaining syllabus. Students who invert that order tend to run out of time having revised everything shallowly and nothing well.
Every item here links back to the full Computer Organization and Architecture notes and the original previous-year papers on AcademicArk, so you can check the exact wording the examiner used instead of relying on a paraphrase. Wording matters: the same concept is often asked as a definition one year and as a numerical the next.

Frequently asked questions
Which COA numerical should I practise first?
Booth's algorithm for signed multiplication, followed by cache mapping and hit-ratio calculations. Both recur year after year and are graded on the working, which makes them dependable marks.
Is pipelining worth preparing in depth?
Yes. Pipeline hazards and speedup calculations are asked frequently, and the speedup formula is simple enough that the question becomes almost free once you have worked a few examples.
Is it safe to study only these COA important questions?
No, and treating any list this way is risky. Repeated topics indicate where the examiner has focused historically, not what will definitely be asked. Use the list to prioritise, then cover the rest of the syllabus at least once.
How were these questions selected?
By frequency of appearance across the previous-year papers available on AcademicArk. Topics asked repeatedly across multiple sessions rank highest, so the list reflects the examiner's actual pattern rather than prediction.
