Research, in common parlance, refers to the search for knowledge. One can also define research as a scientific and systematic search for pertinent information on a specific topic. In fact, research is an art of scientific investigation. It can be described as a careful investigation or enquiry, especially through search for new facts in any branch of knowledge. It is basically a systemized effort to gain new knowledge. Some people consider research as a movement from the known to the unknown. It is actually a voyage of discovery. We all possess the vital instinct of inquisitiveness for the unknown facts. When anything unknown confronts us, our inquisitiveness probes us to attain a complete understanding of the unknown. This inquisitiveness is the mother of all knowledge and methods, which man employs for obtaining the knowledge of the unknown, which we call the research.
