Before getting too deep into Drivers, its important to understand some basics first, starting with the SystemSKU

Dell assigns each computer a SystemSKU as its unique identifier. You can easily determine your System Sku by using the following PowerShell command

(Get-CimInstance -ClassName Win32_ComputerSystem).SystemSKUNumber

When executing this on my computer, I get a return of 0832. Remember this number ... you'll be tested on this soon enough

Using the same CimInstance Class, I can also get the Manufacturer and Model as well

The SystemSKU is what is is matched by OSDDrivers or Driver Automation Tool to determine the correct Dell Driver Pack to apply
