====== Segmentation Fault (SEGFAULT) ======
[[dido:public:ra:xapend:xapend.a_glossary:start| Return to Glossary ]]

A **Segmentation Fault (SEGFAULT)**, or **Access Violation**, is an error returned by hardware with memory protection that tells the operating system that a memory access violation has occurred. The operating system usually reacts by telling the offending process about the error through a signal and then the OS performs some sort of corrective action. This happens because a process or program tries to access memory that is not assigned to it.
