E-commerce refers to the buying and selling of goods or services over the Internet. It has several advantages, such as providing customers with a wider selection of products to choose from globally and potentially lower costs. However, it also has disadvantages like the inability to physically examine products and not everyone having Internet access. Electronic data interchange (EDI) is a commonly used business-to-business e-commerce technology that facilitates electronic transfer of documents between organizations and their suppliers and customers. The wireless application protocol (WAP) is a specification that standardizes how wireless devices can access the Internet for things like email and websites.
