Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
Gray-box extensibility is a compromise between a pure white-box and a pure black-box approach, which does not rely fully on the exposure of source code. Programmers could be given the system’s specialization interface which lists all available abstractions for refinement and specifications on how extensions should be developed.
This suggested that a market existed for a laptop-style computer that would take advantage of the user's reduced need for portability, allowing for higher-performance components, greater expandability, and higher-quality displays. Mobile workstations are also often used with a port replicator, to full enjoy the desktop comfort.
In this guide, we address the question “What is computer health” to help you better monitor your computer system, while in our blog we dig deeper into this topic. Signs that your computer ...
In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
Reliability, availability and serviceability (RAS), also known as reliability, availability, and maintainability (RAM), is a computer hardware engineering term involving reliability engineering, high availability, and serviceability design. The phrase was originally used by IBM as a term to describe the robustness of their mainframe computers.
Human performance modeling (HPM) is a method of quantifying human behavior, cognition, and processes.It is a tool used by human factors researchers and practitioners for both the analysis of human function and for the development of systems designed for optimal user experience and interaction . [1]
A scalable system is therefore one that allows (in the first case) more people and money to be thrown at the problem to achieve greater performance and capability very rapidly or (in the second case) people and money to be taken away without seriously impacting on the current performance or causing a failure of maintainability; this latter is ...
