Objet (informatique)En informatique, un objet est un conteneur symbolique et autonome qui contient des informations et des mécanismes concernant un sujet, manipulés dans un programme. Le sujet est souvent quelque chose de tangible appartenant au monde réel. C'est le concept central de la programmation orientée objet (POO). En programmation orientée objet, un objet est créé à partir d'un modèle appelé classe ou prototype, dont il hérite les comportements et les caractéristiques.
Fibre (informatique)En informatique, une fibre (fiber en anglais) est un type de thread particulièrement léger. Comme les threads, les fibres partagent le même espace mémoire. Toutefois, les fibres utilisent impérativement un multitâche coopératif là où les threads utilisent en général un multitâche préemptif. Les threads dépendent souvent de l'ordonnanceur (en anglais scheduler) du noyau (en anglais kernel) pour préempter un thread occupé et reprendre l'exécution d'un autre thread.
Web development toolsWeb development tools (often called devtools or inspect element) allow web developers to test and debug their source code. They are different from website builders and integrated development environments (IDEs) in that they do not assist in the direct creation of a webpage, rather they are tools used for testing the user interface of a website or web application. Web development tools come as browser add-ons or built-in features in modern web browsers.
Cooperative multitaskingCooperative multitasking, also known as non-preemptive multitasking, is a style of computer multitasking in which the operating system never initiates a context switch from a running process to another process. Instead, in order to run multiple applications concurrently, processes voluntarily yield control periodically or when idle or logically blocked. This type of multitasking is called cooperative because all programs must cooperate for the scheduling scheme to work.
Indeterminacy in concurrent computationIndeterminacy in concurrent computation is concerned with the effects of indeterminacy in concurrent computation. Computation is an area in which indeterminacy is becoming increasingly important because of the massive increase in concurrency due to networking and the advent of many-core computer architectures. These computer systems make use of arbiters which gives rise to indeterminacy. Patrick Hayes [1973] argued that the "usual sharp distinction that is made between the processes of computation and deduction, is misleading".
