Confuse about this address translation for a while write this blog to clarify

#same

1.Segmentation and paging both use virtual address 2.Segmentation and paging use table to map to the physical memory —

#diff

1.segmentation uses add while paging uses concatenation 2.For segment when stack grows it may be get stack overflow, page can allocate new pages

virtual memory contains stack code and data. For stack it start large address and grows downward.
