Process Management

Every program running on a computer’s CPU is called a process. If a process performs an incorrect operation or has a problem, overall server performance can degrade, so the situation should be monitored carefully.

Parent Process (PPID)

A parent process is also called a preceding process, and it can create child processes.
A parent process can run multiple child processes so that many smaller tasks are processed at the same time.

Child Process

A child process shares files and other resources that the parent process is handling.
It is a process created by forking from the parent process.
In a program, it proceeds as a copy of the parent process while communicating with the parent.
