Description

Unique ID number used by Unix and Windows to reference each running program or process; the PID can be used to get information about the resources a process is using or to end the process.

To end a process on a Unix or Mac OS X computer, type "kill [pid]".
In Windows, type "taskkill [pid]".

Process IDs are not file extensions, but instead are used as identifiers for running processes.
