Assembly: System.Management.Automation (in system.management.automation.dll)
A pipeline executed by the background job can contain cmdlets, functions, scripts, script cmdlets, or any other command-based tasks. It is designed to run commands that take an extended amount of time to complete, but it can run any command in the background.
Background jobs are executed within any number of runspaces, and those runspaces can exist on the local computer or any number of remote computers. See the ChildJobs property for more information on jobs that run on multiple runspaces.
