What are cmdlets and Modules

Cmdlets: Cmdlets, pronounced "command-lets", are simple build-in commands written in a .NET language like C# or VB that are used in the Windows PowerShell environment. They are used to perform a single function, such as managing services, processes, event logs, etc. on a computer system. Cmdlets follow a verb-noun naming pattern, like Get-Process, Stop-Service, etc. They are different from commands in other command-shell environments in that they are instances of .NET classes, not stand-alone executables.

Modules: A module is a set of related Windows PowerShell resources that are organized as a unit and that can be distributed as a single unit. Modules can contain cmdlets, providers, functions, variables, aliases, and much more. Modules can be written in PowerShell and/or compiled as DLLs. They allow you to partition, organize, and abstract your PowerShell code. They are self-contained and can be distributed easily. You can use modules to group your code for easier management and sharing.
