PnP PowerShell and SharePoint Online Management Shell

Question

Hello All,

Just a simple question.

After installing PnP PowerShell for SPO my  SharePoint Online Management Shell behaving same as PnP PowerShell,Why?

 

 Both are similar or the commands run differently on both tools?

 

Please, someone, Explain.

When I Put Command Get-SPOContext on both PowerShell it shows the same result for Online.
