According to wikipedia (2015), artificial intelligence (AI) is the intelligence exhibited by machines or software. It is also the name of the academic field of study in computer science which studies how to create computers and computer software that are capable of intelligent behavior. Major artificial intelligence researchers and other sources define this field as the study and design of intelligent agents, in which an intelligent agent is a system that perceives its environment and takes actions that maximize its chances of success. John McCarthy, who coined the term as far back as 1955, defines it as the science and engineering of making intelligent machines.

Artificial intelligence is a branch of Computer Science concerned with the study and creation of computer systems. Artificial intelligence exhibits some form of intelligence by way of introducing systems that learn new concepts and tasks and also have the ability to reason and draw useful conclusions about the world. Artificial intelligence systems also can understand a natural language or perceive and comprehend a visual scene, and perform other types of feats that require human types of intelligence (Freitas, 1999).

        Artificial intelligence research is highly technical and specialized, and is deeply divided into subfields that often fail to communicate with each other. Some of the division is due to social and cultural factors: subfields have grown up around particular institutions and the work of individual researchers (Drexler, 1986). Artificial intelligence research is also divided by several technical issues. Some subfields focus on the solution of specific problems. Others focus on one of several possible approaches or on the use of a particular tool or towards the accomplishment of particular applications. The central problems (or goals) of artificial intelligence research include reasoning, knowledge, planning, learning, natural language processing (communication), perception and the ability to move and manipulate objects. General intelligence is still among the field’s long-term goals (Bostrom, 2002). Currently popular approaches include statistical methods, computational intelligence and traditional symbolic artificial intelligence. There are a large number of tools used in artificial intelligence, including versions of search and mathematical optimization, logic, methods based on probability and economics, and many others. The artificial intelligence field is interdisciplinary, in which a number of sciences and professions converge, including computer science, mathematics, psychology, linguistics, philosophy and neuroscience, as well as other specialized fields such as artificial psychology (Hanson, 1998).

        According to Moravec, (1999), the field was founded on the claim that a central property of humans, intelligence can be so precisely described that a machine can be made to simulate it. This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings endowed with human-like intelligence, issues which have been addressed by myth, fiction and philosophy since antiquity (Kurzweil, 1999). Artificial intelligence has been the subject of tremendous optimism but has also suffered stunning setbacks. Today it has become an essential part of the technology industry, providing the heavy lifting for many of the most challenging problems in computer science (Yudkowsky, 2003).

        Artificial intelligence also deals with study of ideas to bring into being machines that respond to stimulation consistent with traditional responses from humans, given the human capacity for contemplation, judgment and intention (Vinge, 1993). Each such machine should engage in critical appraisal and selection of differing opinions within itself. Produced by human skill and labor, these machines should conduct themselves in agreement with life, spirit and sensitivity, though in reality, they are imitations. Other researcher has seen artificial intelligence as systems that combine sophisticated hardware and software with elaborate databases and knowledge-based processing models to demonstrate characteristics of effective human decision making. However, the researcher will provide an indebt study into the introduction to artificial intelligence and its application and benefit to human being
