What Are The Differences Between Parent And Child Process?

When examining the distinctions between parent and child processes in computer science, it’s important to consider several key aspects. Firstly, a parent process has the capability to spawn and manage multiple child processes simultaneously. Conversely, a child process may or may not have a parent process, depending on the context.

Processes can come to an end through two primary means: either by the operating system itself or by the actions of a user interacting with the system. Importantly, a parent process possesses the authority to terminate its child processes at its discretion. Conversely, a child process retains the ability to terminate itself autonomously, granting it a degree of independence in this regard. This relationship between parent and child processes forms a fundamental part of process management in computing systems.

What Is Parent Process And Child Process In C?

In the realm of C programming, the fork() function holds a pivotal role in the process creation mechanism within operating systems, such as Unix. Essentially, fork() serves as the gateway for generating a duplicate instance of the currently executing program. This newly spawned instance assumes the title of the “Child process,” while the original program, from which this child process emerges, earns the designation of the “Parent process.” In simpler terms, fork() empowers programmers to effectively replicate their running programs, allowing them to manage and execute parallel tasks concurrently. This capability is a cornerstone of multitasking and parallel processing within the realm of operating systems and C programming.

A parent process is a process that creates one or more child processes. A child process is a new process that is created by a parent process, and inherits certain attributes from its parent.The parent process can have multiple child processes. A child process can have no or one-parent process. A process can be terminated by the operating system or by a user. The parent process can terminate its child processes, and a child process can terminate itself.The C fork() function is a primary method of process creation of an operating system like Unix. The fork() is used for creating a new copy of the calling function. The newly created process is known as the Child process and the process from which the child process is created is known as the parent process.
