What term refers to a computing concept where multiple computer systems are working together on a single problem?

The term that refers to a computing concept where multiple computer systems work together on a single problem is "Distributed System." In a distributed system, resources are spread across multiple interconnected computers, allowing them to collaboratively tackle tasks, share resources, and process data in a coordinated manner. This architecture enhances reliability and scalability, as systems can be added or removed without disrupting the overall functionality.

Distributed systems are characterized by their ability to operate without a centralized control mechanism, meaning that multiple nodes can communicate and contribute to solving a problem simultaneously. This approach is commonly utilized in various applications, such as cloud computing, cluster computing, and peer-to-peer networks, where workloads can be distributed and processed in parallel.

In contrast, other concepts such as embedded systems focus on specialized applications within individual devices, and a central control system implies a singular authoritative entity directing operations, rather than multiple systems collaborating. Autonomous agents refer to self-directed systems that operate independently rather than as a collective unit working on a shared problem. Thus, "Distributed System" encapsulates the collaborative nature of the computing concept described in the question.
