What B2C (Business-to-Consumer) is

An acronym that describes the thousands of e-commerce Web sites which sell products directly to the public (the consumer market). B2C is different from the B2B sector, and this distinction is important when comparing Web sites. Each approach has its own business model, strategy, execution, and fulfillment. NetLingo.com has a B2C component that includes selling books (including NetLingo: The Internet Dictionary) and smiley merchandise.

The meaning of Supply chain management

A subset of value chain management, it is an old system that's been updated with new technology. It specifically refers to the relationship between a supplier and a retailer. For example, a major retailer can monitor surplus on its shelves right down to an individual product, and this enables the retail store to keep its supplier aware of how its product is selling. In return, the retailer may demand favorable promotions from the supplier.
