This book is conceived in an effort to make the concepts easy to understand in
the lucid flow of language. The objective that has been tried to achieve is to
make the book as much interesting as possible so as to repulse the boredom in
students and avoid the feeling of "Just another theoretical course book".
For realization of above, few new approaches towards effective learning have
been introduced such as:
* Learning Objectives: Each chapter starts with the purpose of learning.
* The Insight: The Insight is a short introduction mostly by means of real
examples.
* Wisdom
