System architecture
Definition
A system architecture diagram is a visual representation of a system's components, including hardware and software, and how they interact with each other, essentially providing a high-level overview of the system's structure and how different parts connect and function together; it acts as a blueprint to understand the design and functionality of a system at a glance.

"System architecture diagram shows two Zigbee sensor nodes with photoelectric sensors and XBee modules sending data to a Raspberry Pi for local processing. A telemetry node with temperature, DC voltage, and AC voltage sensors connects by Ethernet through an open-access MAN to AWS IoT, Kinesis, EMR, Hadoop, and Spark services, which support QuickSight dashboards and other applications."
