4.Brief introduction of electronic commerce



Online shopping

With the development of the Internet and the popularization of computers, shopping on the Internet has become a commonplace in our life. Here we can buy almost everything we need. We don't have to waste our energy and precious time to go from one shop to another to choose the goods we like. All we need to do is to sit in front of our computers and click the mouses. 
Online shopping is a kind of electronic commerce, which is commonly known as e-commerce. It consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. Generally it has three important modes. 

Electronic commerce that is conducted between businesses is referred to as Business-to-business or B2B. B2B can be open to all interested parties or limited to specific, pre-qualified participants.

Business that sells products or provides services to end-user consumers is referred to as Business-to-customers or B2C. While business-to-consumer activity exists both online and offline, the acronym B2C has primarily been used to describe the online variety.

Electronic commerce involves the electronically facilitated transactions between consumers through some third party is referred to Consumer-to-consumer or C2C. A common example is the online auction, in which a consumer posts an item for sale and other consumers bid to purchase it; the third party generally charges a flat fee or commission.
