d) Given the architectural client/server configurations in Figure 1 that show how applications can be split across computer1 (client) and computer2 (server), use the following table to answer the following questions:
Show the middleware for each configuration.
Which configuration will be most secure?
Which configuration will give the best performance?

- User Performance at Computer1 (Low, Medium, High)
- Network traffic generated between computer 1 and computer2 (Low, Medium, High)
PROBLEM 2:UNDERSTANDING SYSTEM INTEGRATION (15 POINTS)
3A: Find and list three different definitions of architecture and three different definitions of integration. Choose the one that you like the most in each category.
3B: Find and list three different examples of integrated systems and three examples of systems that are not integrated. Just give a 1-2-line description of the system, its URL (if available), and the reason why do you think the system is integrated or not. You can use any examples from any systems anywhere in the world.
