Segmentation faults can also occur independently of page faults: illegal access to a valid page is a segmentation fault, but not an invalid page fault, and segmentation faults can occur in the middle of a page (hence no page fault), for example in a buffer overflow that stays within a page but illegally overwrites memory.
Core dumps can save the context (state) of a process at a given state for returning to it later. Systems can be made highly available by transferring core between processors, sometimes via core dump files themselves. Core can also be dumped onto a remote host over a network (which is a security risk). [11]
On x86 there exists an older memory management mechanism known as segmentation. If the application loads a segment register with the selector of a non-present segment (which under POSIX-compliant OSes can only be done with assembly language), the exception is generated. Some OSes used that for swapping, but under Linux this generates SIGBUS.

Scientists say they’ve confirmed Earth’s inner core has been slowing down. Here’s what it could mean — and why the topic has been the subject of fierce debate.
The SIGQUIT signal is sent to a process by its controlling terminal when the user requests that the process quit and perform a core dump. SIGSEGV The SIGSEGV signal is sent to a process when it makes an invalid virtual memory reference, or segmentation fault, i.e. when it performs a segmentation violation. [19] SIGSTOP
Three companies will pay $110 million to the state of Ohio to settle a lawsuit charging them with dumping "forever" chemicals in the Ohio River.
Segfault (1998–2001) was a popular humor website that posted fake news reports on hacker-related topics on a near-daily basis. The range of topics was approximately the same as that covered and regularly discussed on the Slashdot — including free software , Internet phenomena, computer programming , and technology in general.
