Internet has become an essential part of life globally. Though devised primarily to facilitate research, information seeking, interpersonal communication, and business transactions, Internet has become the central focus of people's lives and a temptation that is hard to resist. Despite its various benefits, it also causes serious negative effects due to overuse of Internet. Although research on this excessive internet use has been existing for the past two decades, the concept of Internet overuse is still ill-defined. It goes by different names such as, internet addiction, problematic internet use, pathological internet use, compulsive internet use, excessive internet use, heavy internet use. Some researchers view it as a form of addiction that is more clinical or pathological, while some view it as a mere behavior excess causing distress. This paper attempts to provide a conceptual definition that may be applied universally.
