Technical features new to Windows VistaWindows Vista (formerly codenamed Windows "Longhorn") has many significant new features compared with previous Microsoft Windows versions, covering most aspects of the operating system. In addition to the new user interface, security capabilities, and developer technologies, several major components of the core operating system were redesigned, most notably the audio, print, display, and networking subsystems; while the results of this work will be visible to software developers, end-users will only see what appear to be evolutionary changes in the user interface.
Algorithme génétiqueLes algorithmes génétiques appartiennent à la famille des algorithmes évolutionnistes. Leur but est d'obtenir une solution approchée à un problème d'optimisation, lorsqu'il n'existe pas de méthode exacte (ou que la solution est inconnue) pour le résoudre en un temps raisonnable. Les algorithmes génétiques utilisent la notion de sélection naturelle et l'appliquent à une population de solutions potentielles au problème donné.
Features new to Windows 7Some of the new features included in Windows 7 are advancements in touch, speech and handwriting recognition, support for , support for additional s, improved performance on multi-core processors, improved boot performance, and kernel improvements. Windows 7 retains the Windows Aero graphical user interface and visual style introduced in its predecessor, Windows Vista, but many areas have seen enhancements. Unlike Windows Vista, window borders and the taskbar do not turn opaque when a window is maximized while Windows Aero is active; instead, they remain translucent.
Valeur vie clientIn marketing, customer lifetime value (CLV or often CLTV), lifetime customer value (LCV), or life-time value (LTV) is a prognostication of the net profit contributed to the whole future relationship with a customer. The prediction model can have varying levels of sophistication and accuracy, ranging from a crude heuristic to the use of complex predictive analytics techniques. Customer lifetime value can also be defined as the monetary value of a customer relationship, based on the present value of the projected future cash flows from the customer relationship.
Rosace (architecture)vignette|300px|La rosace du bras nord du transept de la cathédrale Notre-Dame de Paris. En architecture et en décoration, une rosace ou rose est une ouverture (baie) en forme de rose dans un mur, dans une cloison, dans un garde-corps, dans une séparation bâtie qui délimite un espace. Ces ouvertures sont destinées à fournir le jour mais pas la vue. La rosace est préalablement aussi l'élément de décor sculpté, sans aucune ouverture. Ces éléments présentent une forme circulaire symétrique centrée avec des portions de courbes.
Customer retentionCustomer retention refers to the ability of a company or product to retain its customers over some specified period. High customer retention means customers of the product or business tend to return to, continue to buy or in some other way not defect to another product or business, or to non-use entirely. Selling organizations generally attempt to reduce customer defections. Customer retention starts with the first contact an organization has with a customer and continues throughout the entire lifetime of a relationship and successful retention efforts take this entire lifecycle into account.
Name bindingIn programming languages, name binding is the association of entities (data and/or code) with identifiers. An identifier bound to an object is said to reference that object. Machine languages have no built-in notion of identifiers, but name-object bindings as a service and notation for the programmer is implemented by programming languages. Binding is intimately connected with scoping, as scope determines which names bind to which objects – at which locations in the program code (lexically) and in which one of the possible execution paths (temporally).
Internet Key ExchangeLe Internet Key Exchange (IKE) est un protocole informatique utilisé pour mettre en place les informations de sécurité partagées dans IPsec. IKE a été défini en premier dans les , et puis il évolue comme IKEv2 dans la (cependant "Obsoleted by: 5996", lui-même "Obsoleted by: 7296", ce dernier étant accessible sur la page https://tools.ietf.org/html/rfc7296). IKE utilise l'échange de clés Diffie-Hellman pour mettre en place un secret partagé d'où les clefs de chiffrement sont dérivées.
