A deployment diagram is a type of UML diagram that shows the physical arrangement of hardware and software components in a system, illustrating how software components are deployed on hardware nodes. It is crucial for understanding the architecture of a system, especially in distributed systems, as it helps in visualizing the relationship between software and hardware components.

Distributed systems consist of multiple interconnected components that communicate and coordinate their actions by passing messages to achieve a common goal. They offer scalability, fault tolerance, and resource sharing, but also introduce challenges such as network latency, data consistency, and system complexity.
