In simple terms, a Powershell alias is an alternative name for a cmdlet, function, executable, script, and so on.
Parameters in powershell, also known as arguments, options or switches, help with the passage of arguments or allow users to provide input.
We’ll learn how to discover new cmdlets using get-command, as well as, how to get information on what a cmdlet does and how it can be used, using get-help.
