    I don't know much about this concept but i can give you start...you can refer ..Book written by galvin on operating system
    Ok
    so Whenever you write a program ..it is to be stored somewhere in memory
    so memory segments are used to store the code in it..overall we can say
    the purpose is to store code,data,stack etc in different parts of memory.... but there should be some way to specify the starting
    address of each such segments.....so in short what i want to convey is"segment registers hold the
    starting address of these segment"
    I hope this will help you...
    Please feel free to corect me

    if a system has 32bit address bus ,the addressable memory space is 4 GB
    is it mean that if i install RAM more then 4GB ,the microprocessor can not address RAM addresses above 4GB
