Differentiate between B2C, B2B, C2C, and C2B.
- B2C—Businesses sell their goods and services directly to consumers, using the Internet to conduct business. If you have ever purchased anything online, you participated in a B2C transaction. Examples of B2C businesses include Amazon.com and Souk.com.
- B2B—The buyers and sellers are both businesses. For example, retailers can connect with wholesalers to restock their supply when inventory reaches a reorder point. As the security of the transactions between retailers and wholesalers is very important in B2B transactions, an extranet would typically be used.
- C2C—Individual consumers sell to one another using the Internet. Many use sites like eBay or Craigslist.
- C2B—Individual consumers sell their goods and services to companies. For example, a freelance writer might contract with a publisher to write documentation. He may have limited access to the company’s resources using a secure connection, such as a VPN.
