Explanation:
Process can start either in foreground. Running the process in foreground allows only one command can enter at a time because we will get the shell to type another command until finishing the current command. But background process allows to run the more than one command at a time. To run the process in background just append the & at the end of the command.

Example:
# find / -name passwd >result & We can suspend the jobs running in foreground by pressing ctrl+z shortcut. As well as can resume the suspended jobs either in background or foreground.
#fg %jobid : Runs the job in foreground #bg %jobid : Runs the job in background or #fg command
