    Q1 what is premptive and non preemptive in operating system

    I know
    general purpose operating system support non preemptive scheduling and non preemptive kernel

    real time operating system support preemptive scheduling and preemptive kernel

    I am not really going to design just I want learn something before design

    I want to design my real time operating system , so I need features , requirement component and tool

    I need to develop program For real time operating system
    my effort
    1)basic tool
    compiler
    linker
    debugger

    2)language
    c language

    3)requirement

    requirement of real time os should be fast

    features
    kernel
    - micro kernel
    scheduler - real time scheduler
    multitasking -
    multitasking
    scheduling -
    preemptive scheduling


    I think I have forgotten some features

    I know that window ce and RT Linux both are different type of real time os
    but I don't understand the basic difference

    window ce
    micro kernel
    priority based scheduling
    multitasking
    shared memory
    interrupt handler

    RT LInux

    micro kernel
    priority based scheduling
    multitasking
    shared memory
    interrupt handler

    both have common features so what is basic difference between them

    You can't compare on a limited feature list.

    My Car
    Red
    Four Wheels
    Steering Wheel
    Gas Pedal
    Brakes
    Air Conditioning

    Your Car
    Red
    Four Wheels
    Steering Wheel
    Gas Pedal
    Brakes
    Air Conditioning

    How can you tell the difference, if you can.
