What is stream and buffer in nodeJS?
A buffer is a temporary memory that a stream takes to hold some data until it is consumed. In a stream, the buffer size is decided by the highWatermark property on the stream instance which is a number denoting the size of the buffer in bytes. A buffer memory in Node by default works on String and Buffer .

What are streams in programming?
STREAMS is a general, flexible programming model for UNIX system communication services. STREAMS defines standard interfaces for character input/output (I/O) within the kernel, and between the kernel and the rest of the UNIX system. The mechanism consists of a set of system calls, kernel resources, and kernel routines.
What is streaming JavaScript?
The Streams API allows you to programmatically access streams of data received over the network or created by whatever means locally and process them with JavaScript. Streaming involves breaking down a resource that you want to receive, send, or transform into small chunks, and then processing these chunks bit by bit.

How do streams work?
How does streaming work? Just like other data that’s sent over the Internet, audio and video data is broken down into data packets. Each packet contains a small piece of the file, and an audio or video player in the browser on the client device takes the flow of data packets and interprets them as video or audio.
