Answer to Question 1

The three-tier architecture is an arrangement of user computers and servers into three categories, or tiers. The user tier consists of computers, phones, and other mobile devices that have browsers that request and process Web pages. The server tier consists of computers that run Web servers and process application programs. The database tier consists of computers that run a DBMS that processes requests to retrieve and store data. Web servers are programs that run on a server-tier computer and manage traffic by sending and receiving Web pages to and from clients. A commerce server is an application program that runs on a server-tier computer. Typical commerce server functions are to obtain product data from a database, manage the items in a shopping cart, and coordinate the checkout process.
