Computer Networks Important Questions for AKTU Exams
These are the Computer Networks (CN) questions that AKTU has asked most often, compiled from previous-year papers for semester 5 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.

The topics below account for a large share of the marks in most past papers:
• the OSI and TCP/IP layer comparison • sliding window protocols, including go-back-N and selective repeat • CSMA/CD and Ethernet operation • distance vector versus link state routing, with Dijkstra traced on a graph • TCP connection establishment, congestion control, and flow control • IP addressing and subnetting numericals
Subnetting and routing numericals are the most reliable marks in the paper because they are mechanical once practised. The layer-comparison question is effectively guaranteed, and a clean table answer earns more than a paragraph.
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 Networks 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 Computer Networks question is most likely to appear?
A comparison of the OSI and TCP/IP models, and an IP addressing or subnetting numerical. Both appear in the large majority of past papers.
How much of Computer Networks is numerical?
A meaningful share — subnetting, Hamming distance, CRC, sliding window efficiency, and Dijkstra tracing are all worked questions, and they are the easiest marks to secure with practice.
Is it safe to study only these CN 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.
