    Fundamentally, there are multiple process spaces. The two majors are
    system processes
    users processes​
    the user process space is isolateded from, other users and other processes owned
    by the same user; ie: one program can not write into the process space of another.

    system processes have much broader access rights, and depending upon the
    specific OS, may even have the right to view/alter the memory of another process.
