1.	What does DAG refer to in Apache Spark?
Answer» DAG stands for Directed Acyclic GRAPH with no directed cycles. There WOULD be finite VERTICES and edges. Each edge from one vertex is directed to ANOTHER vertex in a sequential manner. The vertices refer to the RDDs of Spark and the edges represent the operations to be performed on those RDDs.
