What is a PID?
Career: Pids
PIDs, or Process Identifiers, are unique numerical labels assigned by an operating system to each active process running on a computer. They help the system and users track, manage, and control processes such as starting, stopping, or monitoring them. PIDs are essential for system administration, as they make it possible to target specific processes when using commands like 'kill' or 'ps' in Unix-based systems. Each time a new process starts, the OS assigns it a new PID, and the number may be reused after a process ends.
