How and what is Nuget server used for?

Question

.NET

Hello,
I do not quite understand how the internal / local Nuget server is used in the IIS --->> .NET backend bundle. Specifically, Nuget is used when we attach our packages to the compiled code, after which everything is copied to the backend VM's and from the same machine and called? Or are the packages still sitting on the Nuget server and when required they are pumped / called to the instances where this backend is executed.?
Can someone describe a simple architecture how it works in production?

Answer 1

• Local Nuget is used so that private code does not go to the auditorium (I translate into commonly understood Russian - to public repositories).
  
• You will not add any packages to the already compiled code, they must be pulled before building the project.
  
• Servers have nothing to do with Nuget production.
