I express my deep gratitude and appreciation to those who agreed in
this project, for their time expended and courage in sharing their
insights with a fledging student. It is to them that I am most
indebted, and I can only hope that the product of our collaboration
benefits each one as much as I benefited from the process.
I had been immeasurably enriched by working under the supervision
of Mr. Suresh kumar the subject (INFORMATICS PRACTICES)
teacher, who has a great level of knowledge and who has an art of
encouraging , correcting and directing me in every situation possible,
which has enabled me to complete the project.
At times, my studies carried out at great coat to those closest to me.
I thank my family and my fellow students for their best
understanding and support.
I acknowledge to all the people who have involved and supported me
in making this project.
Withthanks…
