ACKNOWLEDGEMENT
First and foremost I thank almighty for his blessings. I sincerely express my gratitude to
my seminar guide, Mr. Pramod Pavithran, Reader, CUSAT, for his proper guidance and
valuable suggestions. Am equally indebted to Dr. David Peter, the HOD, Computer
Engineering division and other faculty members for giving me such an opportunity to
learn and present this seminar. If not for the above mentioned persons my seminar
would never have been completed successfully. I once again extend my sincere thanks
to all of them
