    In short word
    there isn't a specific SEGMENT:OFFSET pairs can be used because depending on system and microprocessor.
    for example
    in windows before access a specific phisical address must select a page of memory and after you can addressing a specific location.
    that is calculated from MMU (memory menagement unit)
    for other system i don't know
    for example in the pic16f..
    you can select the address of external RAM and after you can address a specific location on external RAM.
    But in the main RAM fist 20byte is used for pheriferical and external ram.

    i hope that help you
    sorry for my poor english
