The problem domain layers guide us how the software execute on specific networks or computer.
There are different layers in problem solving. The problem domain layer is the first layer which addresses the solution to a problem. Problem doamin can be different for different fields or domains.
In computer sciences, the problem domain identify the problem and its solution. In the problem domain layer, programmer or the person or any organizations who is developing the software program, specify which computers and network will be used to execute the software.
For example, if there is a computer network applications, then the problem domain addresses how to execute it on computer network. While if the application is desktop, then the problem domain addresses which computer (windows, mac or any other) to use to execute the application.
