The word research is combination of “re” and “search,” which means a systematic investigation to gain new knowledge from already existing facts. In other words, research is a scientific understanding of existing knowledge and deriving new knowledge that may be applied for the betterment of mankind. It is basically search for truth. Research contributes significantly to the progress of the nation as well as an individual with commercial, social, and educational advantages. Research is an important parameter to judge the development of any nation. Research is an important component of private and government sectors. Nowadays, interdisciplinary research is at high demand.

Research should always aim at providing efficient solutions to routine problems. Researchers should carefully choose the appropriate research method and follow a research process by referring to existing theories. Research differs from a traditional way of education, that is, learning concepts and writing the examination or performing activity. According to Clifford Woody, “Research comprises of defining and redefining problems, formulating the hypothesis for suggested solutions, collecting, organizing and evaluating data, making deductions and reaching conclusion and further testing the conclusion whether they fit into formulating the hypothesis.”
