In order to understand “segmentation fault,” it is a must to know the basic idea of segmentation and its implementation in C programming. When we need to execute any program, it should be loaded into memory first. Here, memory is divided into equal sizes of partitions where the code of a program resides.

It is desirable for a program to be able to go to sleep and then wake up a little while later. The answer is hardware interrupts. The OS programs a timer chip that then triggers an interrupt that wakes up the CPU and the OS can then schedule your thread. Timer interrupts and their raison d’être. Decades of madness.

These techniques work well for scientific programs that are dominated by arrays. However, they are ineffective on object-based programs because objects do not fall neatly into fixed-size blocks and have a more irregular layout. If we compress objects instead of cache lines though, we can get to a 56% compression ratio (c).
