The IBM i Operating system
This is what we call background processes. ie: procedures quietly running and doing things that do not need human interaction. Think of web service, or a printer spooling up a PDF, or a process that runs every time you turn the machine on.
In IBM I SPEAK everything that executes is called a JOB.
So if something is running in the background, it is called a BATCH JOB
If you are using a screen, a terminal, physically using your fingers to type in a keyboard (or touchscreen of course) then you are using a INTERACTIVE JOB
Most people run software on their PC's to emulate the old-fashioned terminals. These screens are called 5250 Emulators - because 5250 was the old name for the clunky hardware used 50 years ago.
