Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
In a shared memory multiprocessor machine each CPU and cache module are connected together via a bus that also includes memory and IO connections. The bus enforces a cache coherency protocol. See also cache, coherence, Mbus, XDBus.

A fatal error occurs in the SAX parser when a document is not well formed or otherwise cannot be processed. See also error, warning.
Industry:Computer
In a set associative cache, there are a fixed number of locations (at least two) where each block can be placed. A set associative cache with n locations for a block is called an n-way set associative cache. An n-way set associative cache consists of more than one set, each of which consists of n blocks. A block can be placed in any location (element) of that set. Increasing the associativity level (number of blocks in a set) increases the cache hit rate. See also cache, cache locality, false sharing, write-invalidate, write-update.
Industry:Computer
A DTD specification that defines an element as containing a mixture of text and one more other elements. The specification must start with #PCDATA, followed by diverse elements, and must end with the "zero-or-more" asterisk symbol (*).
Industry:Computer
In a multiprocessor system, true parallel execution is achieved where a large number of threads or processes can be active at one time. See also concurrence, multiprocessor system, multithreading, uniprocessor.
Industry:Computer
In a JMS publish/subscribe messaging system, a subscription that continues to exist whether or not there is a current active subscriber object. If there is no active subscriber, the JMS provider retains the subscription's messages until they are received by the subscription or until they expire.
Industry:Computer
A distinct, individual item that can be included in an XML document by referencing it. Such an entity reference can name an entity as small as a character (for example, <, which references the less-than symbol or left angle bracket, <). An entity reference can also reference an entire document, an external entity, or a collection of DTD definitions.
Industry:Computer
In a concurrent environment, the first process to access data for writing has exclusive access to it, making concurrent write access or simultaneous read and write access impossible. However, the data can be read by multiple readers.
Industry:Computer
A direct mapped cache is a one-way set associative cache. That is, each cache entry holds one block and forms a single set with one element. See also cache, cache locality, false sharing, fully associative cache, set associative cache, write-invalidate, write-update.
