Answer
A stream handles data in chunks, enabling efficient reading and writing without loading full data.
Quick Answer
A stream is a sequence of data delivered in chunks over time instead of all at once. Node.js uses streams for reading large files, piping HTTP responses, and processing data without loading everything into memory. Types: Readable (data comes in), Writable (data goes out), Duplex (both), Transform (modifies data in transit).
