Process Identifier

In computing, the process identifier (normally referred to as the process ID or just PID) is a number used by most operating system kernels, —such as that of UNIX, Mac OS X or Microsoft Windows— to temporarily uniquely identify a process. This number may be used as a parameter in various function calls allowing processes to be manipulated, such as adjusting the process's priority or killing it altogether.

Famous quotes containing the word process:

    Consumer wants can have bizarre, frivolous, or even immoral origins, and an admirable case can still be made for a society that seeks to satisfy them. But the case cannot stand if it is the process of satisfying wants that creates the wants.
    John Kenneth Galbraith (b. 1908)
