A stream is how a program reads to and writes from a file. When a program needs to create or edit a file, it opens up a "stream" to the file, "streams" the intended data to the file, and then saves it before closing the stream.
A Stream is a sequence of bytes.
Opening a file with the fopen function creates a new stream and establishes a connection between the stream and a file. This may involve creating a new file.
file is one of the storage device
Use an input file stream (ifstream) to read from a file and an output file stream (ofstream) to write to a file. Both can be found in the <fstream> standard library header.
The term stream is a generic abstraction that says nothing about the implementation. However, if we use the analogy that gave it its name, a stream of water, we can better understand how a stream works. A water stream allows water to flow from one point to another in one direction only (downstream, with the flow of the current). If we were to throw a stick into the water, it would be carried downstream by the water where it could then be extracted. Sticks can be inserted or extracted automatically by devices, thus allowing information to pass between those devices.A file stream is a stream that is associated with a device representing a file. If the file is upstream then we can use the stream to extract information from the file. When we extract information from a stream, that stream is known as an input stream; it provides us with information. Conversely, if the file were downstream then we can use the stream to insert information into the file. When we insert information into a stream, that stream is known as an output stream; it carries information away from us.An input/output stream is one where we can both insert and extract information. An input/output file stream is a typical example: we can extract data from the file associated with the stream, process the data (modify it in some way), and then insert the modified data back into the same file. To implement an input/output stream, we simply use two streams associated with the same device: one specifically for input operations, the other specifically for output operations. This implementation detail is hidden from the user, so the stream appears to be a bi-directional stream as far as the user is concerned.
file class contain methods or functions that handle various file stream operations.
The file stream classes (ifstream and ofstream) are derivatives of the I/O stream classes (istream and ostream) that are specific to file input and output.
These streams are classified as mode streams as they read and write data from disk files. the classes associated with these streams have constructos that allows us to specify the path of the file to which they are connected. The FileInputStream class allows us to read input from a file in the form of a stream. The FileOutputStream class allows us to write output to a file stream. Example, FileInputStream inputfile = new FileInputStream ("Empolyee.dat"); FileOutputStream outputfile = new FileOutputStream ("binus.dat");
writes data to a FILE* stream.
To stream video content over an RTMP stream using ffmpeg, you can use the following command: ffmpeg -re -i input video file -c:v libx264 -preset veryfast -tune zerolatency -f flv rtmp://RTMP server address/stream key This command will stream the input video file over RTMP to the specified server address and stream key.

I don't know of an official printer file format. However, if you print to file, the data stream is saved as the .xps format. Perhaps this is what you are looking for.
