Acknowledgement:
This coursework a tough task for us as it was for the first time we were learning this. I would like
to that my tutor Mr. Suryansh Mathema for helping us throughout this task and helped in having better
understanding of this TASK. He was helpful during labs and lecture classes to help us. I would like to thank
my module leader Mr. Bijay Limbu Senihang for this help too. He helped in having depth knowledge of
working of different network models through lecture classes which helped a lot in this project. With their
help it was easy for us to able to do this task easily without any difficulties.

Abstract:
This CourseWork consists of two part (Task A and Task B). Task A is about WAN
model, its function and the processing of communication. We use Comnet III for this task
for devepoment of different types of model of networks. Task B is about different types
layers in OSI model and TCP/IP model and their function, how they help in
communocation. So both the tasks are about communicationg process over a network.
