E-commerce involves buying and selling of goods or services over electronic networks. It includes various types of online business activities like B2B, B2C, B2G, and C2C. Traditional retail involves operating a physical store, while modern retail combines both online and physical store operations through a website and physical location. The differences between online and traditional retail include aspects like display, location, expenses, communication, and technology requirements. Both retail models have advantages and disadvantages related to aspects like product viewing, returns, assistance, and costs. An optimal approach combines traditional and e-commerce retailing to provide comfort to both consumers and producers.
