A process is defined as a program that is currently in execution and competes for CPU time and other system resources. In simple terms, a program by itself does not compete for computing resources such as CPU time or memory, whereas a process does. A program may be stored on disk or written on paper, and even if it is compiled or tested, it does not require system resources until it runs. When a user executes a program, it is loaded from disk into main memory, and at that moment, it becomes a process, since it now competes for CPU time and other resources.
