An answer to this is a very long introductory course in UNIX systems internals. In general, you can find a lot of detail about memory management and allocation in books like ``The Design and Implementation of the FreeBSD Operating System''[1] or even the classic book of Abraham Silberschatz called ``Operating System Concepts''[2].

Please see [1] above for concepts like `process' and `thread' in FreeBSD. > Tell me anything else interesting to know about memory mannagment, does > it use any algorithm to substitute a page when out of pages in memory? This is also explained in [1] above :) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
