kernel I/O components

UNIX coordinates the activities of the kernel I/O components by manipulating shared in-kernel data structures, whereas Windows NT uses object-oriented message passing between kernel I/O components. Discuss three pros and three cons of each approach. Answer: Three pros of the UNIX method: Very efficient, low overhead and low amount of data movement Fast implementation — no coordination needed with other kernel components Simple, so less chance of data loss Three cons: No data protection, and more possible side-effects from changes so more difficult to debug Difficult to implement new I/O methods: new data structures needed rather than just new objects Complicated kernel I/O subsystem, full of data structures, access routines, and locking mechanisms
