What is the best description of E-Commerce?

The best description of E-Commerce is that it is a way to carry out transactions digitally over a network. This definition encompasses the extensive range of activities that E-Commerce facilitates, including buying and selling goods and services online, conducting financial transactions, and exchanging information through the internet or other electronic systems.

E-Commerce allows businesses and consumers to interact without being physically present in a traditional brick-and-mortar setting. This includes various forms of commerce such as business-to-consumer (B2C), business-to-business (B2B), and consumer-to-consumer (C2C) transactions.

Other descriptions, such as conducting business solely in person or limiting commerce to catalogs, do not capture the essence of E-Commerce, which thrives on digital connectivity and the use of online platforms. The idea of E-Commerce being restricted to a platform for digital products is too narrow, as it also encompasses physical goods and services that can be sold in a digital format. Thus, the correct answer provides a comprehensive view of E-Commerce's fundamental purpose and operations.
