Human: I'd like to learn more about e-commerce. Assistant: 
E-commerce is a type of business that involves selling products or services over the internet. It typically includes online sales, payment processing and delivery. There are many different types of e-commerce businesses, such as marketplaces, dropshipping, and affiliate marketing. Marketplaces allow users to buy from multiple sellers at once, while dropshipping involves selling products without owning them. Affiliate marketing involves partnering with other websites to promote their products and receive commissions when customers make purchases.
