What are raw bytes?
they are bytes which haven't been cooked yet
They are probably unprocessed bytes; I suspect you actually meant Raw Data, which hasn't been cooked by the software itself. Processed Raw data sometimes ends up in a databases enabling the data to become accessible for further processing and analysis.
DataInputStream reads raw bytes from a stream and interprets them in various binary formats
read this about JAVA
Hmm "unprocessed bytes" in a data stream of 0s and 1s by the looks of things that need to be cooked by the program before they are of any real use like I mentioned previously.
you mean sautéed
