How does a fork bomb work?

A fork bomb works by creating a large number of processes very quickly in order to saturate the available space in the list of processes kept by the computer's operating system. Not only do fork bombs use space in the process table: each child process uses further processor-time and memory.

What is bomb virus?

A logic bomb is a piece of code inserted into an operating system or software application that implements a malicious function after a certain amount of time, or specific conditions are met.

What is the purpose of fork?

System call fork() is used to create processes. It takes no arguments and returns a process ID. The purpose of fork() is to create a new process, which becomes the child process of the caller.
