Job

Q: How deeply does Practical Automation with PowerShell: Effective scripting from the console to the cloud cover job?

Explains launching, waiting for, and receiving job results, but does not detail job-process internals.

As explained in Practical Automation with PowerShell: Effective scripting from the console to the cloud

A job is an asynchronous PowerShell operation that runs work independently of the interactive command flow.

A job is an asynchronous PowerShell operation that runs work as a background process, allowing the interactive command flow to continue while the work proceeds. section 6.1.2

Use jobs when a command lacks a no-wait option or when several operations should run concurrently:

Start each operation with Start-Job and its own script block. section 6.1.2
Track completion with Get-Job and pause the workflow with Wait-Job. section 6.1.2
Retrieve command results with Receive-Job after the jobs finish. section 6.1.2

Parallel downloads

Start two Invoke-WebRequest commands as separate jobs, wait for both downloads to complete, and then continue the script. section 6.1.2

Start-Job -ScriptBlock {
    Invoke-WebRequest -Uri $UrlA -OutFile $FileA
}
Start-Job -ScriptBlock {
    Invoke-WebRequest -Uri $UrlB -OutFile $FileB
}
Get-Job | Wait-Job

Shows the compact job workflow for launching two downloads and waiting for completion. section 6.1.2
