Final answer:
A Shopping Cart allows customers to add items and continue browsing without disrupting their shopping experience, a convenience essential to online stores.
Step-by-step explanation:
The feature that allows customers to continue browsing after selecting each item they wish to purchase is the Shopping Cart. In an online store, a shopping cart functions similarly to a physical shopping cart in a grocery store; it holds items until you are ready to checkout. With a shopping cart, you can add items if necessary and keep track of them as you continue to browse the store for additional products. The convenience of a shopping cart enhances the user experience by making it easy to manage selections without disrupting the shopping process, a function that the other options like forms-based interface, SSL connection, or virtual memory do not directly provide.
