A function in PowerShell is a way of collecting up a bunch of code to perform one or many different times

A module is a set of functions, grouped together as a convenient unit

13. Different kinds of modules
Script Modules
Binary Modules
Manifest Modules
Dynamic Modules
Script Modules
It’s a single script to create modules whose members include functions, variables, and more. At heart, a script module is simply a Windows PowerShell script with a different extension
Binary Modules
A binary module is a .NET Framework assembly (.dll) that contains compiled code, such as C#. Cmdlet developers can use this type of module to share cmdlets, providers
Manifest Modules
A manifest module is a module that uses a manifest file to describe all of its components, but doesn’t have any sort of core assembly or script. 
It can have assemblies loaded but that only extends the functionality
This is the one you’re most frankly are going to develop
Dynamic Modules
These are short lived modules that are created by the New-Module commandlet.
This type of module enables a script to create a module on demand that does not need to be loaded or saved to persistent storage.
Because it’s short lived it’s not available in the Get-Module cmdlet
