Although it may sound like something out of a parenting handbook or a psychological journal, the term child process actually has nothing to do with human development. If you run a Unix or Linux dedicated server, you have likely encountered child processes without even knowing it. Therefore, it is good to know what child processes are and how they work.
A child process is a process created by another process. The creator process is properly called the “parent process”. The benefit of a child process is that it can start or stop at will without affecting the parent process. The child process is, however, is typically dependent on the parent process. If the parent process dies, the child process becomes an orphan process.
