2. .SYNOPSIS 
3.     This script displays the NICs in a system and their physical
4.     address. 
5. .DESCRIPTION 
6.     This script is a MSDN Sample recoded in PowerShell. The script
7.     first gets all the interfaces on the system, then loops through
8.     them displaying more information about them to the console.
9.     Note the use of Console.Write in the loop at the end. Not quite
10.     sure a better PowerShell equivalent other than creating a
11.     string with all the bytes, then displaying that string.
