Mastering Computer Networks (CN) for BTU Exams

Data Communication and Computer Networks is a core fundamental subject for B.Tech CSE at Bikaner Technical University (BTU). Unlike programming subjects, CN blends deep theory with logical networking concepts. By reviewing the past 5 years of PDFs linked above, you will decode the exact paper pattern and ensure a high CGPA.

Most Repeated Topics in BTU CN Papers

  • OSI model and TCP/IP Model: This is the backbone of the exam. You will almost certainly face a 10-15 mark question asking you to explain the architecture, functions of each layer, and compare the two models.
  • IP Addressing and Subnetting: Be prepared to solve numericals on finding subnet masks, calculating the network ID, and determining broadcast addresses for given IP prefixes.
  • Routing Algorithms: You must understand the step-by-step logic for Distance Vector Routing (Bellman-Ford algorithm) and Link State Routing (Dijkstra's algorithm). Always show the routing table updates in your answer sheet!
  • Network Security: Basic cryptographic principles and algorithms like RSA are frequently asked in the final units.
