process
An executing {program}. A
process consists of the program {code} (which may be shared
with other processes which are executing the same program),
and some private data. It may have other associated resources
such as a {process identifier}, open files, {CPU time} limits,
{shared memory}, {child processes}, and {signal handlers}.
A {multitasking} {operating system} can run multiple processes
{concurrently} or in {parallel}.
