In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1] It can sometimes be a high-level description that ignores details of the implementation. [ 2] At a more detailed level, the description may include the instruction set architecture design ...
A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates.

A system architecture primarily concentrates on the internal interfaces among the system's components or subsystems, and on the interface (s) between the system and its external environment, especially the user. (In the specific case of computer systems, this latter, special, interface is known as the computer human interface, AKA human ...
The von Neumann architecture —also known as the von Neumann model or Princeton architecture —is a computer architecture based on a 1945 description by John von Neumann, and by others, in the First Draft of a Report on the EDVAC. [ 1] The document describes a design architecture for an electronic digital computer with these components: The ...
Software development. 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.
Service-oriented architecture. In software engineering, service-oriented architecture ( SOA) is an architectural style that focuses on discrete services instead of a monolithic design. [ 1] SOA is a good choice for system integration. [ 2] By consequence, it is also applied in the field of software design where services are provided to the ...
4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [ 1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers. The four views of the model are logical ...
The NIST Enterprise Architecture Model is a five-layered model for enterprise architecture, designed for organizing, planning, and building an integrated set of information and information technology architectures. The five layers are defined separately but are interrelated and interwoven. [2] The model defined the interrelation as follows: [3 ...
