Computer Networks' Question Papers!!!

Computer Networks  -->>

These are the questions compiled together from all the previous years' question papers of COMPUTER NETWORKS. So first try to prepare these topics and then go for the whole book. :-)

NOTE: The number in bracket denotes the number of times the question has been asked in previous exams.

1. Explain any 2 IEEE 802 standards with the format of the frames. (4)
2. What is a window? Explain the concept of sliding window. Explain in short the two methods used in sliding window protocol along with the window sizes required at the sender and the receivers side and why? (4)
3. Unguided transmission medium (3)
4. Congestion. Various methods of preventing and reducing the in congestion in the network. (3)
5. Network security? Symmetric and Asymmetric methods to make the data secure and explain the RSA algorithm in detail.
