Final answer:
Client-server architecture involves a division into clients making requests and servers providing services, while layered architecture is a system divided into layers each with a specific role, such as presentation, business logic, and data access layers.
Step-by-step explanation:
Client-server architecture and layered architecture are two different types of system architectures used in network and software design. In client-server architecture, the system is divided into two types of machines: clients that request services and servers that provide services. This architecture is often used in web applications where the server hosts the application services, and the client is typically a web browser that makes requests to the server.
In contrast, layered architecture, also known as n-tier architecture, structures a system into a set of layers where each layer has a specific role and functionality. For example, a three-layer architecture commonly has a presentation layer, business logic layer, and data access layer. Layers communicate with each other in a defined order, often with the presentation layer at the top, making requests to the business logic layer, which in turn communicates with the data access layer.
The main distinction between these two architectures lies in their structural approach to component interaction and allocation of responsibilities within a system.
