WebMar 12, 2014 · A system called Network Address Translation, allows the addresses to be rewritten when packets traverse network borders to allow them to continue on to their correct destination. This allows the same IP address to be used on multiple, isolated networks while still allowing these to communicate with each other if configured correctly.

WebThis linear address is translated in a two level page table - the top 10 bits in the page global directory, and the middle 10 bits in the page table, which produces a physical page number that is added to the lower 12 bits of the address to produce the physical address. WebAddress Translation is done by two techniques. Paging. Segmentation. 1. Paging: Physical memory is divided into fixed size block know as Frames. Logical Memory is divided into blocks of same size knows as Pages. When a process is to be executed, its pages are loaded into available memory - -- Paging Hardware : Physical Memory.

WebDec 4, 2012 · logical address: 5 bits (2^5 = 32 bytes) and offset(the lower order part) always is the size of one page, which is 3 bits (2^3 = 8 bytes). Then the first order is therefore 5 - 3 = 2 bits. Translation should be like. get the page number(higher part) and offset of … WebThe address is split into a segment descriptor and an offset. The descriptor indexes into the segment table which produces an address that is added to theoffset to produce the linear address.
