DAGs in Computer Science
A Directed Acyclic Graph (DAG) is a type of data structure made up of nodes (points) connected by arrows (edges) that show relationships. The key features are that each arrow has a direction (from one node to another) and that there are no loops—meaning you can't start at one node and follow arrows back to it. DAGs are used to model processes like task scheduling, version control, or data flow, where dependencies matter and cycles would cause confusion. They help organize and visualize how different elements relate without redundancies or contradictions.
