System software was usually supplied by the manufacturer of the computer hardware and was intended to be used by most or all users of that system. Many operating systems come pre-packaged with basic application software. Such software is not considered system software when it can be uninstalled without affecting the functioning of other software.
Software engineering is an engineering approach to software development. [1] [2] [3] A practitioner, a software engineer, applies the engineering design process to develop software. The terms programmer and coder overlap software engineer, but they imply only the construction aspect of typical software engineer workload.
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. [1] [2]
Computer-aided software engineering ( CASE) is a domain of software tools used to design and implement applications. CASE tools are similar to and are partly inspired by computer-aided design (CAD) tools used for designing hardware products. CASE tools are intended to help develop high-quality, defect-free, and maintainable software. [1]
Software development. In software engineering, software configuration management ( SCM or S/W CM; also expanded as source configuration management process and software change and configuration management [1]) is the task of tracking and controlling changes in the software, part of the larger cross-disciplinary field of configuration management.

The history of software engineering begins around the 1960s. Writing software has evolved into a profession concerned with how best to maximize the quality of software and of how to create it. Quality can refer to how maintainable software is, to its stability, speed, usability, testability, readability, size, cost, security, and number of ...
Component-based software engineering. 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.
In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape. The V-Model demonstrates the relationships ...
