Which of the following is a characteristic of two-tier computing?

• A. The server handles both presentation and business logic
• B. The client is responsible for presentation and business logic
• C. Both client and server manage data equally
• D. Only the server stores user data

Answer: (B)

In two-tier computing architecture, the client is responsible for both presentation and business logic. This setup allows the client application to handle the user interface and application logic, while the server primarily focuses on data management and storage. By offloading the tasks related to presentation and business logic to the client, it ensures that the server's resources are dedicated to data handling, leading to potentially improved performance and a clearer separation of concerns.

The correct answer accurately reflects this division of responsibility in a two-tier architecture, where clients typically interact directly with the database through the application logic implemented on the client side. This design model is quite common in applications where the complexity of business logic doesn't require a more sophisticated three-tier structure, making it suitable for many straightforward applications.
