E-commerce, or electronic commerce, refers to the buying and selling of goods and services over the internet. It has transformed the way consumers shop, allowing them to browse products from the comfort of their homes and make purchases with just a few clicks. This convenience has led to a significant increase in online shopping, with platforms like Amazon and eBay leading the charge. In addition to traditional online retail, e-commerce encompasses various models, including B2B (business-to-business) and C2C (consumer-to-consumer) transactions. Mobile commerce, or m-commerce, is also on the rise, enabling consumers to shop using their smartphones and tablets. As technology continues to evolve, e-commerce is expected to grow even further, reshaping the retail landscape.
