Using jobs
Many of the PowerShell scripts we will create will execute in a serial fashion, that is, A starts before B which starts before C. This method of processing is simple to understand, easy to create, and easy to troubleshoot. However, sometimes there are processes that make serial execution difficult or undesirable. In that situation, we can look at using jobs as a method to start a task, and then move it to the background so that we can begin the next task.
A common situation I ran into is needing to get information, or execute a command, on multiple computers. If it is only a handful of systems, standard scripting works fine. However, if there are dozens, or hundreds of systems, a single slow system can slow down the entire process.
