Modular programming is a software design technique that emphasizes separating the functionality of a program into independent, interchangeable modules, such that each contains everything necessary to execute only one aspect or "concern" of the desired functionality. A module interface expresses the elements that are provided and required by the ...
In software engineering, the module pattern is a design pattern used to implement the concept of software modules, defined by modular programming, in a programming language with incomplete direct support for the concept.
Separation of concerns is an important design principle in many other areas as well, such as urban planning, architecture and information design. [5] The goal is to more effectively understand, design, and manage complex interdependent systems, so that functions can be reused, optimized independently of other functions, and insulated from the ...
Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma , Richard Helm , Ralph Johnson , and John Vlissides , with a foreword by Grady Booch .
EDSAC, on which the book was based, was the first computer in the world to provide a practical computing service for researchers. [2] Demand for the book was so limited initially that it took six years to sell out the first edition. [7] As computers became more common in the 1950s, the book became the standard textbook on programming for a time ...
Modular computer design. Modular design in computer hardware is the same as in other things (e.g. cars, refrigerators, and furniture). The idea is to build computers with easily replaceable parts that use standardized interfaces. This technique allows a user to upgrade certain aspects of the computer easily without having to buy another ...

Component-based software engineering (CBSE), also called component-based development (CBD), is a style of software engineering that aims to construct a software system from components that are loosely-coupled and reusable. This emphasizes the separation of concerns among components. [1] [2]
