Electronic commerce, commonly written as
e-commerce, is the
trading or facilitation of trading in products or services using computer networks, such as the
Internet. Electronic commerce draws on technologies such as
mobile commerce,
electronic funds transfer,
supply chain management,
Internet marketing,
online transaction processing,
electronic data interchange (EDI),
inventory management systems, and automated
data collection systems. Modern electronic commerce typically uses the
World Wide Web for at least one part of the transaction's life cycle, although it may also use other technologies such as e-mail.
