WBUT-Level Multiple Choice and Short Questions on Computer Networks with Explanations

This article compiles a comprehensive list of multiple-choice and 1-mark questions related to Computer Networks, specifically designed according to the WBUT (West Bengal University of Technology) curriculum. Organized by topic, it includes areas like Data Communication, Physical Layer, Data Link Layer, and Medium Access Sub-Layer. Each question is followed by the correct answer and a brief explanation, ensuring clarity and aiding in concept reinforcement.

Key concepts such as frequency behavior in signals, modulation techniques (ASK, FSK, PSK), Manchester encoding, mesh topology, HDLC protocols, error detection and correction methods (like Hamming codes and parity checks), and sliding window protocols are covered. The explanations often cite the rationale or underlying principle, such as how instantaneous signal changes imply infinite frequency or how selective repeat ARQ retransmits only erroneous frames.

The resource is particularly useful for engineering students preparing for WBUT exams or anyone revising foundational networking concepts. The logical structure and categorized content also make it a handy review sheet for quick reference or last-minute study.

Overall, the article serves as both a knowledge check and a learning aid, bridging academic objectives with practical understanding of network protocols and architectures.
