Typical elements of a window.The window decoration is either drawn by the window manager or by the client. The drawing of the content is the task of the client. In computing, a windowing system (or window system) is a software suite that manages separately different parts of display screens. [1]
The model is an interface defining the data to be displayed or otherwise acted upon in the user interface. The view is a passive interface that displays data (the model) and routes user commands to the presenter to act upon that data. The presenter acts upon the model and the view. It retrieves data from repositories (the model), and formats it ...
In computing, a shell is a computer program that exposes an operating system's services to a human user or other programs. In general, operating system shells use either a command-line interface (CLI) or graphical user interface (GUI), depending on a computer's role and particular operation. It is named a shell because it is the outermost layer ...
A GDI printer or Winprinter (analogous to a Winmodem) is a printer designed to accept output from a host computer running Windows. The host computer does all print processing: GDI renders a page as a bitmap, which the printer driver receives, processes, and sends to the associated printer.
A graphical user interface (GUI) showing various elements: radio buttons, checkboxes, and other elements. A graphical user interface, or GUI [a], is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation.
The NETCONF protocol can be conceptually partitioned into four layers: The Content layer consists of configuration data and notification data. The Operations layer defines a set of base protocol operations to retrieve and edit the configuration data. The Messages layer provides a mechanism for encoding remote procedure calls (RPCs) and ...
The OSI model comprises seven abstraction layers. Each layer of the model encapsulates and addresses a different part of the needs of digital communications, thereby reducing the complexity of the associated engineering solutions. A famous aphorism of David Wheeler is, "All problems in computer science can be solved by another level of ...
The model of the graphics pipeline is usually used in real-time rendering. Often, most of the pipeline steps are implemented in hardware, which allows for special optimizations . The term "pipeline" is used in a similar sense for the pipeline in processors : the individual steps of the pipeline run in parallel as long as any given step has what ...
