HEY DUDE ITS....
It can give error that Office Suite cannot be started due to lack of RAM. This is not very nice from usability perspective.It can decide or suggest to kill firefox process to free up RAM. Again this is not very nice from usability perspective.It can shift some of the memory pages (RAM pages) of firefox which firefox has not used recently and write them to disk. If firefox tries to access this pages, after they are removed from RAM, page fault will occur because page will not be there. This page fault would be handled by OS. As part of page fault handling OS will re-read the memory page from disk (persistent slow storage) and write it to RAM. If required to free up RAM OS might swap some other page from memory.
HOPE IT HELPS....
