Evolutionary model is also referred to as the successive versions model and sometimes as the incremental model. In Evolutionary model, the software requirement is first broken down into several modules (or functional units) that can be incrementally constructed and delivered.
Tutorial Topic: Network Topology Definition, features, example, diagram, network topology advantages and disadvantages of all the types of network topology - Bus topology, Ring topology,…
A computer network is a set of devices (often referred to as nodes) connected by communication links. A node can be a computer, printer, or any other device capable of sending or receiving data from the other node/device through the network.
What is Line Configuration? Two or more devices connected through a link is a network. A link is a transmission path through which data is…
Software maintenance is the process of modifying a software system or component after delivery to correct faults, improve performances or other attributes, or adapt to a changed environment.
A prototype model is a toy/demo implementation of the actual product or system. A prototype model usually exhibits limited functional capabilities, low reliability, and inefficient performance as compared to the actual software.
At a technical level, software engineering begins with a series of modeling tasks that lead to a complete specification of requirements and a comprehensive design representation for the software to be built. The first technical representation of a system which is the analysis model, actually a set of models. There have been many methods proposed for analysis modeling.
The requirements elicitation and specification phase starts when the feasibility study phase is completed and the project is found to be technically and feasible. The goal of the requirements analysis and specification phase is to understand client requirements and to systematically organize these requirements in a specification document.
A software requirement specification (SRS) is a comprehensive information/description of a product/system to be developed with its functional and non-functional requirements. The software requirement specification (SRS) is developed based on the agreement between customer and supplier.
A good software design implies clean decomposition of the problem into modules and the neat arrangement of these modules in a hierarchy. The primary characteristics of neat module decomposition are low coupling and high cohesion. Cohesion is a measure of functional strength of a module.
