In computing, a process is an instance of a computer program that is being executed.
The process contains the program code and its current activity.
Description
Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently.
A computer program is a passive collection of instructions; a process is the actual execution of those instructions.
Multiple processes
Several processes may be associated with the same program; for example, opening up several instances of the same program often means more than one process is being executed.
