Electronic commerce, commonly known as
e-commerce or
e-comm, refers to the buying and selling of
products or
services over electronic systems such as the
Internet and other
computer networks. Electronic commerce draws on such technologies as
electronic funds transfer,
supply chain management,
Internet marketing,
online transaction processing,
electronic data interchange,
inventory management systems, and automated data collection systems. Modern electronic commerce typically uses the
World Wide Web at least at one point in the transaction's life-cycle, although it may encompass a wider range of technologies such as
e-mail, mobile devices and telephones as well.
