Operating system concepts

what is difference between threads and child processes and light weight processes?

p.s. i have referred to two books by tanenbaum and i have found contradictory answers. thats why i am asking here!!

    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. 😀

    Hi Simple,

    Your query will be surely solved by the following books:

    1.Operating Systems Concepts - Silberschatz Galvin
    2.Operating Systems - Achyut S. Godbole

    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!!
