'''Segmentation''' is one of the most common ways to achieve [[memory protection]]; another common one is [[paging]]. In a computer system using segmentation, an instruction operand that refers to a memory ___location includes a value that identifies a segment and an offset within that segment. A segment has a set of permissions, and a length, associated with it. If the currently running [[Process (computing)|process]] is allowed by the permissions to make the type of reference to memory that it is attempting to make, and the offset within the segment is within the range specified by the length of the segment, the reference is permitted; otherwise, a hardware [[Exception handling|exception]] is delivered.
