PowerShell is OOP Program all the command return object and if you want to know what type you pipe it to Get-Memeber

Get-Process | gm (GM is Alias of  Get-Memeber command)

you can see in the typename: the .Net Object (C# Object) and you can go to MSDN site to read about this object

An object can have Properties like Name Description Id etc... depend on the Object

Can Have Event like Process Disposed, ErrorDataReceived etc...

Can Have Method like Close, Kill, CloseMainWindow etc...

In Powershell, it can also have AliasProperites and Script Properties, CodeProperty
