Resource Allocation Graph

A Resource Allocation Graph (RAG) is a directed graph used in operating systems to model resource allocation and detect deadlocks. It visually represents processes as circles, resources as squares, and edges to show allocation requests and assignments. This tool helps analyze system states to identify potential deadlock conditions like circular wait.

Also known as: RAG, Resource Graph, Allocation Graph, Deadlock Detection Graph, Process-Resource Graph

Why learn Resource Allocation Graph?

Developers should learn RAG when working on operating systems, concurrent programming, or distributed systems to understand and prevent deadlocks. It's essential for designing resource management in multi-threaded applications, databases, or server environments where processes compete for shared resources, ensuring system reliability and efficiency.
