Answer / Amar Deep Singh Yadav
Data in Spark is represented as RDDs, DataSets, or DataFrames. RDDs are distributed collections of objects and support both immutable and mutable operations, while DataSets provide a type-safe API for RDDs and are immutable. DataFrames extend DataSets to support structured data with a schema, allowing for easier manipulation and analysis.
