In the single-lock strategy, a thread acquires a single, application-wide mutex lock whenever any thread in the application is running and releases the lock before the thread blocks. The single-lock strategy requires cooperation from all modules and libraries in the system to synchronize on the single lock. Because only one thread can be accessing shared data at any given time, each thread has a consistent view of memory. This strategy is quite effective in a uniprocessor, provided shared memory is put into a consistent state before the lock is released and that the lock is released often enough to allow other threads to run. Furthermore, in uniprocessor systems, concurrency is diminished if the lock is not dropped during most I/O operations. The single-lock strategy cannot be applied in a multiprocessor system.

A Java class that can be manipulated by tools and composed into applications. A JavaBeans component must adhere to certain property and event interface conventions.

In the shared memory architecture, a mechanism for caches to communicate with each other as well as with main memory. In packet switching, traffic is divided into small segments called packets that are multiplexed onto the bus. A packet carries identification that enables cache and memory hardware to determine whether the packet is destined for it or to send the packet on to its ultimate destination. Packet switching allows bus traffic to be multiplexed and unordered (not sequenced) packets to be put on the bus. The unordered packets are reassembled at the destination (cache or main memory). See also cache, shared memory.
Industry:Computer
In the Java Message Service, an asynchronous request, report, or event that is created, sent, and consumed by an enterprise application and not by a human. It contains vital information needed to coordinate enterprise applications, in the form of precisely formatted data that describes specific business actions.
Industry:Computer
In the distributed memory architecture, a mechanism for processes to communicate with each other. There is no shared data structure in which they deposit messages. Message passing allows a process to send data to another process and for the intended recipient to synchronize with the arrival of the data.
Industry:Computer
A highly optimized Java runtime environment targeting a wide range of consumer products, including pagers, cellular phones, screen phones, digital set-top boxes, and car navigation systems.
Industry:Computer
In systems with multiple caches, the mechanism that ensures that all processors see the same image of memory at all times.
Industry:Computer
A hardware feature where operations are reduced to multiple stages, each of which takes (typically) one cycle to complete. The pipeline is filled when new operations can be issued each cycle. If there are no dependencies among instructions in the pipe, new results can be delivered each cycle. Chaining implies pipelining of dependent instructions. If dependent instructions cannot be chained, when the hardware does not support chaining of those particular instructions, then the pipeline stalls.
