| A program is a file that is stored on a physical piece of media that can be run to perform a series of tasks.
A process is what you call that program when it is loaded into and running in memory. The list of all processes running on the computer is output with the command:
ps -ef
Sometimes a process can get stuck or go into an infinite loop. Looking at the process table with ps or with the command top is a good way to check on your processes. Top is available on Skunkware.
