+ "On UNIX, the adage goes, everything is a file."
- not all the things on unix are abstracted as files (or 'byte streams' to be more accurate). however, i/o resources and some ipc facilities are defined so. an operating system provides many other abstractions in addition to these such as processes, threads, non-stream devices, concurrency and synchronization primitives, etc.; thus it's absolutely wrong to say that everything is a file on unix.
