    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    CPU Bound jobs are jobs that spend most of their time using the CPU, although they do preform I/O operations as well.

    I/O Bound jobs are jobs that spend most of their time doing I/O, although they do use the CPU as well.

    When a process is cpu-bound it is limited by the available cpu cycles.

    When i/o/ bound it is limited by the speed of disk i/o

    In either case, if you add resource: - more cpu or faster disk access -- the program speeds up.
