What is e-commerce?

E-commerce refers specifically to the buying and selling of goods and services over the internet. This encompasses a wide range of online business activities, including retail sales, digital services, and even the trading of goods through platforms that facilitate transactions between consumers and businesses. The core concept of e-commerce revolves around the ability to conduct commercial transactions electronically, which has transformed how businesses operate and how consumers shop and engage with products and services.

The other options represent different aspects of online activities. Electronic banking pertains to online financial transactions rather than the broader concept of commerce. Sharing financial information securely relates to data security but does not encompass the entire process of buying and selling. Platforms for social networking focus on connecting people and sharing content, which is distinct from commercial transactions. Therefore, e-commerce is uniquely characterized by its focus on transactions, making it a crucial component of the digital economy.
