Memory protection - memory protection; storage protection
This refers to protecting the contents of a certain part of a computer's memory by making it programmatically write-protected. Special hardware is used to perform memory protection, and in many cases, if the address of an instruction points to a memory protection address, the instruction is rejected. Memory protection is applied to the resident parts of an operating system, parts of other programs when multiple programs are being processed simultaneously, and important data parts of auxiliary memory devices.
