'''Segmentation''' is one of the most common ways to achieve [[memory protection]]; another common one is [[paging]]. Segmentation means that a part or parts of the memory will be sealed off from the currently running [[Process (computing)|process]], through the use of [[hardware register]]s. If the data that is about to be read or written to is outside the permitted [[address space]] of that process, a [[segmentation fault]] will result.
