What is segmentation fault?
Answer / srinivasan rajagopalan
A segmentation fault (often shortened to segfault) is a
particular error condition that can occur during the
operation of computer software. A segmentation fault occurs
when a program attempts to access a memory location that it
is not allowed to access, or attempts to access a memory
location in a way that is not allowed (for example,
attempting to write to a read-only location, or to overwrite
part of the operating system).
Segmentation is one approach to memory management and
protection in the operating system. It has been superseded
by paging for most purposes, but much of the terminology of
segmentation is still used, "segmentation fault" being an
example. Some operating systems still have segmentation at
some logical level although paging is used as the main
memory management policy.
On Unix-like operating systems, a process that accesses an
invalid memory address receives the SIGSEGV signal
