Many advancements on roadways throughout the years were made as each new form of transportation was improved. Then one day man could fly and hence another form of transportation made it possible for man to go from place to place in a fraction of the time compared to car or rail road. Along with these improved modes of transportation came new and inherent risks like head on collisions in vehicles, planes falling from the sky, and tunnel collapses in subways. With risk and threat comes the need for security and safety practices. Cars were made safer and roadways were improved to include guard rails, painted lines, traffic lights and stop signs. As the population grew so did the need to expand the ability to move about. In terstates were built, airports were built and subways were now a means of travel in the urban setting. As technology and the transportations system grew so did the threat and risk of damage from either natural or manmade disasters. We take for granted every day the roads we travel believing or thinking that nothing can or will happen to them where we live.

The secondary in formation and data were collected from published books, journals, research papers, and official statistical documents. Reports published on ‘e-commerce’ by Organization of Economic Cooperation and Development (OECD) provides important ideas regarding the topic. Electronic commerce, or e-commerce, is the buying and selling of goods and services on the Ziaul Hoq et al Internet. Other than buying and selling, many people use Internet as a source of information to compare prices or look at the latest products on offer before making a purchase online or at a traditional store. E- business is sometimes used as another term for the same process. More often, though, it is used to define a broader process of how the Internet is changing the way companies do business, of the way they relate to their customers and suppliers, and of the way they think about such functions as marketing and logistics. For the purpose of this study e-commerce is taken to mean doing business electronically. (Lindsay P. , 2002) Other terms that are often used when talking about e-commerce are B2B and B2C, shorthand for business-to-business, where companies do business with each other, and business-toconsumer, where companies do business with consumers using the Internet. These are considered to be main forms of e-commerce The advent and spectacular growth of the Internet have spawned claims of a ‘new economy’ governed by a ‘new economics’. Economists rarely endorse such claims, pointing out that basic microeconomic and macroeconomic principles still apply. Shapiro (1999, p. 2) for example comments that –‘Fortunately, history can still be our guide †¦while we cannot rely much on the classical model of perfect competition and price setting firms, we don’t need a fundamentally new economics’. Shapiro and Varian (1999, p. ) argue that, ‘even though technology advances breathlessly, the economic principles we rely on are durable’. However, while the underlying economic principles remain unchanged, e-commerce and the Internet have significantly altered firms’ cost structures and raised the importance of certain economic phenomena, including network economics. Shapiro (1999) argue s that, ‘networks, interconnection and leveraging are not new phenomena, just increasingly important’. While the prominence of network effects may not constitute new economics, or even a new economy, it is clear that there has been a marked and permanent break with the past.
