Answer to Question 1

Almost all e-commerce applications use the three-tier architecture, which is an arrangement of user computers and servers into three categories or tiers. The user tier consists of computers, phones, and other 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.

Answer to Question 2

FALSE
Explanation: It should be stressed that the purpose of a walkthrough is to detect errors, not to correct them. It is the programmer's job to correct the errors uncovered in a walkthrough.
