save and access data even in the presence of machine failures. See

To learn more about memory management, refer to a book
that deals with operating system theory, and especially with the
operating systems used on web server machines.
A good starting point is one of the classic textbooks used in
operating system courses. For example:
Operating System Concepts, by Abraham
Silberschatz and Peter Baer Galvin (John Wiley & Sons, Inc.).
Applied Operating System Concepts, by Abraham
Silberschatz, Peter Baer Galvin, and Greg Gagne (John Wiley &
Design of the Unix Operating System, by Maurice
Bach (Prentice Hall).
The Memory Management Reference at http://www.xanalys.com/software_tools/mm/ is
also very helpful.
