Question related to WMI

Hello,

I am new to Power Shell , and I try to learn its syntax and functionalities.

I am trying to understand the Get_WmiObject syntax and usage from the Microsoft web site (https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/get-wmiobject?vie...)

Get instances or information of the Windows management Instruction or (WMI) is defined as
Get-WmiObject

[-Class]
[[-Property] ]
[-Filter ]
[-Amended]
[-DirectRead]

[-AsJob]
[-Impersonation ]
[-Authentication ]
[-Locale ]
[-EnableAllPrivileges]
[-Authority ]
[-Credential ]
[-ThrottleLimit ]
[-ComputerName ]
[-Namespace ]
[]

I have few question regarding the defined WMI class and I would like to seek your helps and expertise.

1) Does the Get-WmiObject [-Class] represent a instance of a class in the Get-WmiObject ,
and is the instance of that class of type String ?
