What is the difference between network architecture and application architecture?

Network Architecture and Application Architecture are two different aspects of a system's overall architecture, each with its own specific focus and purpose.

1. Network Architecture: This refers to the design of a computer network. It includes the physical layout (like devices and cables) and the functional organization (like protocols and data formats). It's about how computers are connected, how information is transmitted between them, and how they work together to provide network services. Network architecture can be categorized into two types: Peer-to-Peer (P2P) and Client/Server.

2. Application Architecture: This is the architecture of an individual software application. It's about how the application is structured over various components, how these components interact with each other, and how they are deployed and executed. It includes aspects like software layers, data models, and user interfaces. Application architecture can be categorized into several types, such as Monolithic, Microservices, and Event-Driven.

In summary, while network architecture is about the design of the entire computer network, application architecture is about the design of individual software applications within that network.
