Here are some of the key aspects of e-commerce:

Convenience: E-commerce allows customers to shop from anywhere, anytime, without having to leave their homes. This is a major advantage over traditional brick-and-mortar stores, which are limited by their physical location and operating hours.
Selection: Online stores typically offer a much wider selection of products than brick-and-mortar stores. This is because online stores are not limited by physical space constraints.
Prices: E-commerce stores can often offer lower prices than brick-and-mortar stores. This is because online stores have lower overhead costs, such as rent and utilities.
Information: Online stores can provide customers with a wealth of information about products, such as reviews, specifications, and pricing comparisons. This can help customers make informed purchasing decisions.
Personalization: Many e-commerce stores use personalization techniques to tailor the shopping experience to each individual customer. This can include things like recommending products based on past purchases or browsing history.
E-commerce has grown rapidly in recent years, and it is now a major part of the global economy. In 2023, e-commerce sales are expected to reach $5.7 trillion worldwide.
