Can you name the main types of software system architectures?

The main types of software system architectures include:

• Monolithic architecture — all components of the application are tightly coupled and work as a single unit.
• Client-server architecture — separation into client and server parts, where the client requests data and the server processes it.
• Microservices architecture — the application is divided into independent services that interact via APIs.
• Layered architecture — the application is divided into layers (e.g., presentation, business logic, data access).
• Event-driven architecture — components interact through events and handlers.
• MVVM (Model-View-ViewModel) — popular in Flutter, separates presentation logic from business logic.

The choice of architecture depends on project requirements, scalability, and ease of maintenance.
