What are the primary components of a system architecture diagram?

The primary components of a system architecture diagram focus on illustrating how different elements of a system interact with one another and their physical arrangement. System connectivity and physical locations are crucial because they provide a clear visual representation of how components are connected, where they are located in a network, and the overall structure of the system. This helps stakeholders understand the layout of the system, the flow of data, and where specific resources are allocated.

In contrast, while network security protocols, data encryption techniques, and user authentication methods are important aspects of a cybersecurity strategy, they represent specific elements of security rather than fundamental components of a system architecture. These elements serve to protect the architecture but do not define its basic structure or connectivity. The architecture diagram primarily emphasizes how different parts of the system work together and their geographic distribution, making system connectivity and physical locations the key focus area.
