E-Commerce

Electronic commerce (e-commerce) involves business that is done electronically and includes economic exchange between businesses (B2B), businesses selling to consumers (B2C), or exchange between individual consumers (C2C). By the twenty-first century, e-commerce had become increasingly central to affluent economies, as a result of the creation of vast telecommunications networks and the Internet; the proliferation of personal computers and mobile phones; developments in business systems, software, and websites; and the establishment of trust in vendor reliability and personal financial information security (especially credit cards), through promotional marketing and advances in encryption.
