Difference between different memory types
hey guys i m confused totally about the memory management in operating systems.
the tutorial at
tldp.org under memory management
under section 3.1 "An Abstract Model of Virtual Memory" says
'In this paged model, a virtual address is composed of two parts; an offset and a virtual page frame number. If the page size is 4 Kbytes, bits 11:0 of the virtual address contain the offset and bits 12 and above are the virtual page frame number. '
Can anyone pls explain this...
and also tell the difference between
physical memory address, main memory address, logical address, virtual address. i m really quite confused...
or give a link to the tutorial to clarify my doubt... pls.. i need to know them urgently....
