Could you explain what is meant by architectural style in system design?

Architectural style in system design is a set of principles and patterns that define the structure and interaction of system components. It sets general rules for organizing the system, affecting its scalability, maintainability, and performance.

For example, REST is an architectural style for web services that defines how clients and servers should interact via HTTP, using standardized methods and resources.

Choosing an architectural style helps developers agree on approaches to building the system and makes the code easier to understand and maintain.
