job, task and process, what's the difference

Question

what is the difference between these concepts?

Answer 1

They can be all considered the same thing, really depends on the context. A process though is usually an isolated entity that's managed by the operating system. A job is often more of an application level term or just some script that's executed to do a specific set of task(s). A task is often a part of a job - sometimes the only part.
