    Seminar 2004 VoIP-Voice over Internet Protocol Department of Electronics & Communication Govt Engineering College Thrissur VoIP (Voice over Internet Protocol) Submitted On Submitted by 15-10-04 Lakshmi Menon S7 ECE 630 Co-ordinator:Muneera C R Dept of ECE GEC,TRICHUR Seminar 2004 VoIP-Voice over Internet Protocol ACKNOWLEDGEMENT First,and foremost I thank God Almighty for making this venture a success. I extend my sincere gratitude to Prof. Indiradevi, Head of Electronics and Communication Department, Govt Engineering College, Thrissur for providing me with necessary infrastructure. I would like to convey a deep sense of gratitude to the seminar co-ordinator Mrs. C R Muneera for the timely advices. I also extend my sincere thanks to my friends for their help. Dept of ECE GEC,TRICHUR Seminar 2004 VoIP-Voice over Internet Protocol ABSTRACT The development of very fast, inexpensive microprocessors and special-purpose switching chips, coupled with highly reliable fibre-optic transmission systems, has made it possible to build economical, ubiquitous, high speed packet-based data networks. Similarly, the development of very fast, inexpensive digital signal processors (DSPs) has made it practical to digitize and compress voice and fax signals into data packets. The natural evolution of these two developments is to combine digitized voice and fax packets with packet data, creating integrated data-voice networks. The voice-over-Internet protocol (VoIP) technology allows voice information to pass over IP data networks. Primarily, the cost savings that accrue from operating a single, shared network have motivated this convergence of telecommunications and data communications. VoIP allows you to make telephone calls using a computer network, over a data network like the Internet.

    ISLAND CONNECTIONS: MOBILE PHONES AND SOCIAL CHANGE IN RURAL FIJI By RYAN PESECKAS A DISSERTATION PRESENTED TO THE GRADUATE SCHOOL OF THE UNIVERSITY OF FLORIDA IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY UNIVERSITY OF FLORIDA 2014 1 © 2014 Ryan Peseckas 2 To my parents, who have given me love and unconditional support in all of my pursuits 3 ACKNOWLEDGMENTS I wish to acknowledge the assistance of a number of individuals, communities and organizations, without whose generous help and cooperation I could not have successfully completed this research. At the University of Florida I thank first and foremost my committee chair, Gerald Murray. Jerry took me on as a graduate student in 2006 despite my lack of undergraduate training in anthropology, and has offered helpful advice and encouragement at each step of the way. Peter Collings served as a committee member for both my master’s and PhD research, and likewise has provided much advice, as well as assistance with reading drafts and writing letters of recomendation. I also wish to thank the members of my committee, C.K. Shih, Abdoulaye Kane, and Michael Bannister, for agreeing to oversee my project and for providing valuable input throughout. Also at the University of Florida I am grateful to Christopher McCarty, who went out of his way to assist me with my data analysis, and Paul Richards, who supervised me as a teaching assistant and has been very supportive in my search for post-graduate employment. Finally, I thank my fellow graduate students at the University of Florida, who have been my friends and colleagues during the 7 memorable years I have spent in Gainesville.
