Service-oriented design can separate concerns into services.
For example, object-oriented programming languages such as C#, C++, Delphi, and Java can separate concerns into objects, and architectural design patterns like MVC or MVP can separate content from presentation and the data-processing (model) from content. The mechanisms for modular or object-oriented programming that are provided by a programming language are mechanisms that allow developers to provide SoC. 3.5 Levels of analysis in artificial intelligence.So despite the many benefits of well-separated concerns, there is often an associated execution penalty.

As with most abstractions, separating concerns means adding additional code interfaces, generally creating more code to be executed. Separation of concerns is a form of abstraction.

Modules can also expose different versions of an interface, which increases the freedom to upgrade a complex system in piecemeal fashion without interim loss of functionality. Hiding the implementation details of modules behind an interface enables improving or modifying a single concern's section of code without having to know the details of other sections and without having to make corresponding changes to those other sections.
When concerns are well-separated, there are more opportunities for module upgrade, reuse, and independent development. Common among these is increased freedom for simplification and maintenance of code. Separation of concerns results in more degrees of freedom for some aspect of the program's design, deployment, or usage. Layered designs in information systems are another embodiment of separation of concerns (e.g., presentation layer, business logic layer, data access layer, persistence layer). Encapsulation is a means of information hiding. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface. A program that embodies SoC well is called a modular program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". Each section addresses a separate concern, a set of information that affects the code of a computer program. In computer science, separation of concerns ( SoC) is a design principle for separating a computer program into distinct sections. Design principle for computer programming
