Module
A module is a package that
contains PowerShell commands, such as cmdlets, providers, functions, workflows,
variables, and aliases.
People who write commands can use
modules to organize their commands and share them with others. People who
receive modules can add the commands in the modules to their PowerShell
sessions and use them just like the built-in commands.
Examples
Get modules imported into the
current session
PS C:\> Get-Module
Get installed modules and
available modules
PS C:\> Get-Module –ListAvailable
Get all exported files
PS C:\> Get-Module -ListAvailable –All
