Ian Sommerville's research work, partly funded by the EPSRC [5] has included systems requirements engineering and system evolution. He defined the process of Construction by configuration (CbC). A major focus has been system dependability , including the use of social analysis techniques such as ethnography to better understand how people and ...
Thus, generic systems are purchased and configured to create a specific version applied to an organization context by adapting modules to structures, business lines and processes. In his work, Sommerville identified three (3) types of configurable systems: single PC-based applications with built-in, modular generic systems (such as ERP systems ...
Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
A software system is a system of intercommunicating components based on software forming part of a computer system (a combination of hardware and software). It "consists of a number of separate programs, configuration files, which are used to set up these programs, system documentation, which describes the structure of the system, and user documentation, which explains how to use the system".
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. [1] A device or program that executes instructions described by that ISA, such as a central processing unit (CPU), is called an implementation of that ISA.

Ian Sommerville (June 3, 1940 – February 5, 1976) [2] was an electronics technician and computer programmer. He is primarily known through his association with William S. Burroughs 's circle of Beat Generation figures, and lived at Paris 's so-called " Beat Hotel " by 1960, when they were regulars there, becoming Burroughs's lover and ...
