C++: What is a stream. The term stream is an abstraction of a construct that allows you to send or receive an unknown number of bytes. The metaphor is a stream of water. You take the data as it comes, or send it as needed. Contrast this to an array, for example, which has a fixed, known length.
Input streams do not allow random access (whatever that may mean) to the data they provide (whatever that might be). Note that this is purely an interface description for a class, nothing more. Where the stream gets its data from / what it does with the data pushed into it, is entirely up to the stream. A stream is an abstraction for recieving/sending data.
