A job is a process (program) that is associated with with a single shell. The command:

jobs

will list all jobs that are running from the current shell. For example: if a user opens a man page for the command ls, this command can be suspended by pressing a control + Z (^Z) combination and the command line prompt would return. If the jobs command were then run the following output would be seen:

[1] + Stopped man ls

The user could then run other commands and then returning to the man command by bringing it to the foreground using:

fg %1

Or this job can be stopped without bringing it back to the foreground by:

kill %1

Jobs that do not need the resources of the console can be restarted in the background by:

bg %1

Finally foreground jobs can also be killed by simultaneously pressing the control key and C (^C) combination.
