This is continuation of part series post of Virtual Memory - Part 1
The posting on this subject is going to be in multiple parts series. It is going to difficult to put everything in one post given the broad nature of the subject.
Signals are a limited form of inter-process communication used in Unix, Unix-like, and other POSIX-compliant operating systems. A signal is an asynchronous notification sent to a process or to a specific thread within the same process in order to notify it of an event that occurred. Signals have been around since the 1970s Bell Labs Unix and have been more recently specified in the POSIX standard.
In computing, particularly in the context of the Unix operating system and its workalikes, fork is an operation whereby a process creates a copy of itself. It is usually a system call, implemented in the kernel. Fork is the primary (and historically, only) method of process creation on Unix-like operating systems.
This post will explore the code flow when Open system call is issued.
