Discuss the difference between a job ID and a process ID.
What will be an ideal response?
In Linux, you use a job identifier (commonly called a job ID) to refer to processes when launching processes from the command line. The job identifier is a shell-specific numeric value that uniquely identifies the running program.
Independent of the shell, each process is identified using a process ID (commonly called a PID) that is unique across the entire system. All jobs have a PID, but not all processes have a usable job ID.
