Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
In XML documents, a piece of text that describes a unit of data or an element. The tag is distinguishable as markup, as opposed to data, because it is surrounded by angle brackets (< and >). To treat such markup syntax as data, you use an entity reference or a CDATA section.
Industry:Computer
A parser that ensures that an XML document is valid in addition to being well formed. See also parser.
Industry:Computer
A parameter that initializes the context associated with a servlet.
Industry:Computer
A number of processors working simultaneously, each handling one element of the array, so that a single operation can apply to all elements of the array in parallel.
Industry:Computer
A hardware feature of some pipeline architectures that allows the result of an operation to be used immediately as an operand for a second operation, simultaneously with the writing of the result to its destination register. The total cycle time of two chained operations is less than the sum of the stand-alone cycle times for the instructions. For example, the TI 8847 supports chaining of consecutive fadd, fsub, and fmul (of the same precision). Chained faddd/fmuld requires 12 cycles, while consecutive unchained faddd/fmuld requires 17 cycles.

In multitasking operating systems, such as the SunOStrademark operating system, processes run for a fixed time quantum. At the end of the time quantum, the CPU receives a signal from the timer, interrupts the currently running process, and prepares to run a new process. The CPU saves the registers for the old process, and then loads the registers for the new process. Switching from the old process state to the new is known as a context switch. Time spent switching contexts is system overhead; the time required depends on the number of registers, and on whether there are special instructions to save the registers associated with a process.
Industry:Computer
A grouping of audit events. Audit classes provide a way to select a group of events to audit. This term is used in XSCF firmware.
Industry:Computer
Software that provides services to an EJB container. For example, an EJB container typically relies on a transaction manager that is part of the EJB server to perform the two-phase commit across all the participating resource managers. The J2EE architecture assumes that an EJB container is hosted by an EJB server from the same vendor, so it does not specify the contract between these two entities. An EJB server can host one or more EJB containers.
