Computer Networks (CSC263) — Official TU Syllabus

The official Tribhuvan University (TU) syllabus for Computer Networks (Course Code: CSC263) defines the complete academic curriculum, unit-wise lecture hour distribution, and laboratory requirements prescribed by the Institute of Science and Technology (IOST) for BSc Computer Science and Information Technology (BSc CSIT) students in the fourth semester.

This course carries a total weightage of 100 marks, divided into internal assessment and end-of-semester board examinations. The internal continuous evaluation accounts for 20% of the total score (20 marks), administered directly by college faculty based on attendance, unit tests, mid-term examinations, and laboratory participation. The final TU board examination conducted by the Controller of Examinations consists of 60 marks for written theoretical assessment and 20 marks for practical laboratory evaluation.

To obtain academic credit for Computer Networks, students must pass theory, practical, and internal evaluations independently with a minimum pass mark of 40%. Specifically, students must secure at least 24 out of 60 marks in the written board examination and at least 8 out of 20 marks in the practical examination.

Syllabus comprehension is the cornerstone of effective exam preparation. By analyzing the lecture hour allocations assigned to each chapter unit in the official Computer Networks syllabus, students can prioritize high-weightage topics such as core theoretical proofs, algorithmic procedures, and practical coding exercises.

We recommend pairing this syllabus document with our verified Computer Networks Chapter Notes and practicing past board exam questions available in our Computer Networks Past Questions. Solving previous years' past questions ensures familiarity with repeat question patterns, time management during exams, and standard diagram requirements expected by TU evaluators.
