Responsiveness
Responsiveness as a concept of computer science refers to the specific ability of a system or functional unit to complete assigned tasks within a given time. For example, it would refer to the ability of an artificial intelligence system to understand and carry out its tasks in a timely fashion. In the Reactive principle, Responsiveness is one of the fundamental criteria along with resilience, elasticity and message driven. It is one of the criteria under the principle of robustness (from a v principle). The other three are observability, recoverability, and task conformance. Vs performance Software which lacks a decent process management can have poor responsiveness even on a fast machine. On the other hand, even slow hardware can run responsive software. It is much more important that a system actually spend the available resources in the best way possible. For instance, it makes sense to let the mouse driver run at a very high priority to provide fluid mouse interactio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agile Construction
Agile construction is an integrated system of principles and methods, and a philosophy of doing business adapted to jobsites and overall project delivery in the construction industry. It is born from agile manufacturing and project management, which is mostly used in manufacturing production, automotive and software developing teams. It is the application of the Toyota Production System to the construction industry, with two parallel paths: Measuring (ASTM E2691) and improving productivity, as well as segregating and externalizing work through prefabrication and supply chain management. Like the Toyota Production System, agile construction principles form a system that relies on input from the source of the work information, both up front for planning the project, as well as throughout the life of a project for real-time feedback. The real-time input produces real-time measurements of productivity and allows for improved responsiveness to changes on the jobsite. Iterative and in ...

Responsive Web Design
Responsive web design (RWD) or responsive design is an approach to web design that aims to make web pages render well on a variety of devices and window or screen sizes from minimum to maximum display size to ensure usability and satisfaction. A responsive design adapts the web-page layout to the viewing environment by using techniques such as fluid proportion-based grids, flexible images, and CSS3 media queries, an extension of the @media rule, in the following ways: * The fluid grid concept calls for page element sizing to be in relative units like percentages, rather than absolute units like pixels or points. * Flexible images are also sized in relative units, so as to prevent them from displaying outside their containing element. * Media queries allow the page to use different CSS style rules based on characteristics of the device the site is being displayed on, e.g. width of the rendering surface (browser window width or physical display size). *Responsive layouts ...

Linux Kernel And Gaming Input-output Latency
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses and recommends the name "GNU/Linux" to emphasize the use a ...

Reliability, Availability And Serviceability
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. Computers designed with higher levels of RAS have many features that protect data integrity and help them stay available for long periods of time without failure. This data integrity and uptime is a particular selling point for mainframes and fault-tolerant systems. Definitions While RAS originated as a hardware-oriented term, systems thinking has extended the concept of reliability-availability-serviceability to systems in general, including software: * ''Reliability'' can be defined as the probability that a system will produce correct outputs up to some given time ''t''. Reliability is enhanced by features that help to avoid, detec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Measurement
Measurement is the quantification of attributes of an object or event, which can be used to compare with other objects or events. In other words, measurement is a process of determining how large or small a physical quantity is as compared to a basic reference quantity of the same kind. The scope and application of measurement are dependent on the context and discipline. In natural sciences and engineering, measurements do not apply to nominal properties of objects or events, which is consistent with the guidelines of the International Vocabulary of Metrology (VIM) published by the International Bureau of Weights and Measures (BIPM). However, in other fields such as statistics as well as the social and behavioural sciences, measurements can have multiple levels, which would include nominal, ordinal, interval and ratio scales. Measurement is a cornerstone of trade, science, technology and quantitative research in many disciplines. Historically, many measurement syste ...

Computer Systems
A computer is a machine that can be Computer programming, programmed to automatically Execution (computing), carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as Computer program, ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the Computer hardware, hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots.

Reactive User Interface
A human-to-computer user interface is said to be "reactive" if it has the following characteristics: #The user is immediately aware of the effect of each "gesture". Gestures can be keystrokes, mouse clicks, menu selections, or more esoteric inputs. #The user is always aware of the state of their data. Did I just save those changes? Did I just overwrite my backup by mistake? No data is hidden. In a figure-drawing program, the user can tell whether a line segment is composed of smaller segments. #The user always knows how to get help. Help may be context-sensitive or modal, but it is substantial. A program with a built-in ''help browser'' is not reactive if its content is just a collection of screen shots or menu item labels with no real explanation of what they do. Reactivity was a major goal in the early user interface research at MIT and Xerox PARC. A computer program which was not reactive would not be considered ''user friendly'' no matter how elaborate its prese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Progress Bar
A progress bar is a graphical control element used to visualize the progression of an extended computer operation, such as a download, file transfer, or installation. Sometimes, the graphic is accompanied by a textual representation of the progress in a percent format. The concept can also be regarded to include "playback bars" in Media player (software), media players that keep track of the current location in the duration of a media file. A more recent development is the , which is used in situations where the extent of the task is unknown or the progress of the task cannot be determined in a way that could be expressed as a percentage. This bar uses motion or some other indicator (such as a barber's pole pattern) to show that progress is taking place, rather than using the size of the filled portion to show the total amount of progress, making it more like a throbber than a progress bar. There are also indeterminate progress indicators, which are not bar shaped. History Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Progress Indicator
A progress indicator is an element of a command-line interface, a textual user interface, or a graphical user interface that is intended to inform the user that an operation is in progress, to reassure that the system is not hung or waiting for user input, and often to provide the user with an estimate of how far through a task the system has progressed. Examples of progress indicators * A progress bar, a typically horizontal bar which is gradually filled with a color as the process completes. * A throbber, an image in a program's interface which animates to show that the software is busy. * A splash screen, covering all or most of the computer screen while a program is loading. * Turning the mouse pointer into an hourglass or a spinning pinwheel to indicate to the user that they should not click anything until the active process is complete. * A simple textual percentage figure, common in CLI applications. * A growing row of dots indicating the progress in loading a file (as d ...
