    Could you also write the answers you saw in the other two books? That would be nice to refer here and correct which ever is wrong or explain both. 😀

    Its not that simple....



    Kernel-supported threads fall into two classes.
    • In a "pure" kernel-supported system, the kernel is responsible for scheduling all threads.
    • Systems in which the kernel cooperates with a user-level library to do scheduling are known as two-level, or hybrid, systems. Typically, the kernel schedules LWPs, and the user-level library schedules threads onto LWPs.
    This is why i was confused....
    thanks anyways!! c ya!!

    thanx xheavenlyx,but i could not find the functioning of operating system in interfacing- moreover why we prefer windows-98 in interfacing.In window-xp we can not access parallel port directly, if so then why... i need perfect help!
