    Hello, I'm a computer science sophomore at CU studying virtual memory for my Computer Systems class, described in the context of Linux, and I'm a little confused as to how it's mapped to the disk. First of all, is the virtual address space all mapped to a contiguous amount of disk space? If so, is this what the swap file is - a contiguous amount of space on disk set aside for a virtual address space? If so, are objects copied into the corresponding areas in a swap file? Or is this swap file just transposed over an object file?

    The damn text is just ambiguous and doesn't fully elaborate on some things. Any help is appreciated.
