In order to understand “segmentation fault,” it is a must to know the basic idea of segmentation and its implementation in C programming. In order to overcome these issues, the concept of paging and segmentation was introduced, where physical address space and virtual address space were designed.

Transparent Huge Pages (THP) is a memory management feature in Linux operating systems that aims to enhance system performance. By default, the majority of widely used Linux distributions employ a virtual memory page size of 4KB. The concept of HugePages in Linux has existed for many years, first introduced in 2007.

Then, development of even higher-level compiled languages like Fortran, COBOL, and their successors C, C++, and Java meant that most programmers no longer wrote assembly code. Consumer operating systems were also a big part of the story. That job was effectively encapsulated in the operating system.

asm goto is a GNU C extension that allows for assembly code to transfer control flow to a limited, known set of labels in C code. With asm goto , we have something more akin to structured exception handling in C++; we’re going to “call” something, and it may jump control flow to an arbitrary location.
