Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
A NaN (not a number) that propagates through almost every arithmetic operation without raising new exceptions.
Industry:Computer
Stands for Not a Number. A symbolic entity that is encoded in floating-point format.

Standard generalised Markup Language. The parent of both HTML and XML. Although HTML shares SGML's propensity for embedding presentation information in the markup, XML is a standard that allows information content to be totally separated from the mechanisms for rendering that content.
Industry:Computer
A module that reads in XML data from an input source and breaks it into chunks so that your programme knows when it is working with a tag, an attribute, or element data. A nonvalidating parser ensures that the XML data is well formed but does not verify that it is valid. See also validating parser.

Standard Error is the Unix file pointer to standard error output. This file is opened when a programme is started.
Industry:Computer
A model of the world that is used to formulate a computer solution to a problem. Paradigms provide a context in which to understand and solve a real-world problem. Because a paradigm is a model, it abstracts the details of the problem from the reality, and in doing so, makes the problem easier to solve. Like all abstractions, however, the model can be inaccurate because it only approximates the real world. See also Multiple Instruction Multiple Data, Single Instruction Multiple Data, Single Instruction Single Data, Single programme Multiple Data.
Industry:Computer
Specifies the implementation of a transaction manager that supports JTA and implements the Java mapping of the Object Management Group Object Transaction Service 1.1 specification at the level below the API.
Industry:Computer
A method of transmitting messages without having to block until a response is received.

Solaris threads are implemented as a user-level library, using the kernel's threads of control, that are called light-weight processes (LWPs). In the Solaris environment, a process is a collection of LWPs that share memory. Each LWP has the scheduling priority of a UNIX process and shares the resources of that process. LWPs coordinate their access to the shared memory by using synchronisation mechanisms such as locks. An LWP can be thought of as a virtual CPU that executes code or system calls. The threads library schedules threads on a pool of LWPs in the process, in much the same way as the kernel schedules LWPs on a pool of processors. Each LWP is independently dispatched by the kernel, performs independent system calls, incurs independent page faults, and runs in parallel on a multiprocessor system. The LWPs are scheduled by the kernel onto the available CPU resources according to their scheduling class and priority.
