stream
1. <communications> An abstraction referring to any flow of data from a
source (or sender, producer) to a single sink (or receiver, consumer). A stream
usually flows through a channel of some kind, as opposed to packets which may be
addressed and routed independently, possibly to multiple recipients. Streams
usually require some mechanism for establishing a channel or a "connection"
between the sender and receiver.
2. <programming> In the C language's buffered input/ouput library
functions, a stream is associated with a file or device which has been opened
using fopen. Characters may be read from (written to) a stream without knowing
their actual source (destination) and buffering is provided transparently by the
library routines.
3. <operating system> Confusingly, Sun have called their modular device
driver mechanism "STREAMS".
4. <operating system> In IBM's AIX operating system, a stream is a
full-duplex processing and data transfer path between a driver in kernel space
and a process in user space.

5. <communications> streaming.
6. <programming> lazy list.
