Memory Segment - Offset - (Relative|Effective) address

Cpu Memory Management Segmented Model


The offset is the second part of a logical address that permits to locate an Address inside a memory segment

Logical Address Segment

A offset is not an address but the (distance|id) of this Address from the start of a memory segment starting at 0.

An offset is also known as:

  • an effective address
  • an address offset

It's the id of the address inside the memory segment



You get the offset in the output of an hexdump generally in the first column.
