File descriptors and network sockets are objects in NT Executive
NT supports asynchronous disk I/O via callback functions and disk I/O API
  • Video server design exploits concurrency using asynchronous I/I
NT also supports asynchronous network I/O!
  • On data arrival, a message is sent to message queue
  • Messages retrieved by polling mechanism
  • On receipt of the message client reads from the network. The mechanism is not blocking
  • Dual buffering combined with asynchronous I/O hides disk and network latencies.
