Client/Server Architecture Quiz

What are the three types of Client/Server systems in existence?

• Two-tier

• Three-tier

• N-Tier

Answer explanation

The three types of Client/Server systems are Two-tier, Three-tier, and N-Tier. Each architecture defines how the client and server interact, with varying levels of complexity and separation of concerns.

What is the definition of the Two-tier Client/Server Model?

Evaluate responses using AI:

OFF

Answer explanation

The Two-tier Client/Server Model consists of a client that interacts directly with a server. The client handles the user interface and application logic, while the server manages data storage and processing.

What are the advantages of Two-Tier Architecture?

• Cost-Effective Tools

• Integration with Tools

• Enhanced GUI Capabilities

• Rapid Application Development (RAD)

• Ease of Implementation

Answer explanation

Two-Tier Architecture offers several advantages including cost-effective tools, seamless integration with existing systems, enhanced GUI capabilities for better user experience, rapid application development, and ease of implementation.

What are the disadvantages of Two-Tier Architecture?

• Increased Network Load

• Complex Update Process

• Complicated Software Distribution

• High Maintenance Cost

• Bound to Individual PCs

Answer explanation

Two-Tier Architecture has several disadvantages including increased network load due to frequent communication between client and server, a complex update process, complicated software distribution, high maintenance costs, and being bound to individual PCs.

What are the responsibilities of the Presentation Layer in a Three-tier architecture?

Evaluate responses using AI:

OFF

Answer explanation

The Presentation Layer in a Three-tier architecture is responsible for user interface and user experience. It handles the presentation of data to users and manages user interactions, ensuring a smooth communication between the user and the application.

What are the responsibilities of the Application Layer in a Three-tier architecture?

Evaluate responses using AI:

OFF

Answer explanation

In a Three-tier architecture, the Application Layer is responsible for business logic, data processing, and communication between the Presentation Layer and the Data Layer, ensuring that user requests are handled efficiently.

What are the responsibilities of the Database Layer in a Three-tier architecture?

Evaluate responses using AI:

OFF

Answer explanation

In a Three-tier architecture, the Database Layer is responsible for data storage, retrieval, and management. It handles database operations, ensuring data integrity and security, and serves as the interface between the application and the data.

What are the core features of the N-tier model?

Evaluate responses using AI:

OFF

Answer explanation

The N-tier model features separation of concerns, scalability, and maintainability. It divides applications into layers (presentation, business logic, data access) to enhance organization and facilitate independent development and deployment.

What is Middleware?

Evaluate responses using AI:

OFF

Answer explanation

Middleware is software that acts as a bridge between different applications or services, enabling communication and data management. It facilitates interactions in distributed systems, making it essential for integration and functionality.

What are the types of Middleware Services?

Evaluate responses using AI:

OFF

Answer explanation

Middleware services can be categorized into types such as message-oriented middleware, object request brokers, database middleware, and web middleware. Each type facilitates communication and data management between distributed systems.
