Industry:Computer
A set of phases during which a request for a page is received, a UI component tree representing the page is processed, and a response is produced. During the phases of the life cycle:
*The local data of the components is updated with the values contained in the request parameters.
*Events generated by the components are processed.
*Validators and converters registered on the components are processed.
*The components' local data is updated to back-end objects.
*The response is rendered to the client while the component state of the response is saved on the server for future requests.

A set of formatting instructions that apply to the nodes selected by an XPath expression.
Industry:Computer
A set of associations between unique, atomic, people-friendly identifiers and objects.

The framework events of a J2EE component's existence. Each type of component has defining events that mark its transition into states in which it has varying availability for use. For example, a servlet is created and has its init method called by its container before invocation of its service method by clients or other servlets that require its functionality. After the call of its init method, it has the data and readiness for its intended use. The servlet's destroy method is called by its container before the ending of its existence so that processing associated with winding up can be done and resources can be released. The init and destroy methods in this example are callback methods. Similar considerations apply to the life cycle of all J2EE component types: enterprise beans, Web components (servlets or JSP pages), applets, and application clients.

The field values of a session bean plus the transitive closure of the objects reachable from the bean's fields. The transitive closure of a bean is defined in terms of the serialization protocol for the Java programming language, that is, the fields that would be stored by serializing the bean instance.

System model where there are many processing elements, but they are designed to execute the same instruction at the same time; that is, one program counter is used to sequence through a single copy of the program. SIMD is especially useful for solving problems that have lots of data that needs to be updated on a wholesale basis; such as numerical calculations that are regular. Many scientific and engineering applications (such as, image processing, particle simulation, and finite element methods) naturally fall into the SIMD paradigm. See also array processing, pipeline, vector processing.
Industry:Computer
System model where many processors can be simultaneously executing different instructions on different data. Furthermore, these processors operate in a largely autonomous manner as if they are separate computers. They have no central controller, and they typically do not operate in lock-step fashion. Most real world banks run this way. Tellers do not consult with one another, nor do they perform each step of every transaction at the same time. Instead, they work on their own, until a data access conflict occurs. Processing of transactions occurs without concern for timing or customer order. But customers A and B must be explicitly prevented from simultaneously accessing the joint AB account balance. MIMD relies on synchronization mechanisms called locks to coordinate access to shared resources. See also mutual exclusion, mutex lock, semaphore lock, single-lock strategy, spin lock.
Industry:Computer
A portion of a JSP page that is recognized by a JSP translator. An element can be a directive, an action, or a scripting element.
