In computer science, distributed shared memory ( DSM) is a form of memory architecture where physically separated memories can be addressed as a single shared address space. The term "shared" does not mean that there is a single centralized memory, but that the address space is shared—i.e., the same physical address on two processors refers ...
Compare-and-swap. In computer science, compare-and-swap ( CAS) is an atomic instruction used in multithreading to achieve synchronization. It compares the contents of a memory location with a given value and, only if they are the same, modifies the contents of that memory location to a new given value. This is done as a single atomic operation.
In telecommunications and computer networks, a channel access method or multiple access method allows more than two terminals connected to the same transmission medium to transmit over it and to share its capacity. [1] Examples of shared physical media are wireless networks, bus networks, ring networks and point-to-point links operating in half ...
Hardware cache of a central processing unit. A CPU cacheis a hardware cacheused by the central processing unit(CPU) of a computerto reduce the average cost (time or energy) to access datafrom the main memory.[1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main ...

Brewer and Nash model. The Brewer and Nash model was constructed to provide information security access controls that can change dynamically. This security model, also known as the Chinese wall model, was designed to provide controls that mitigate conflict of interest in commercial organizations and is built upon an information flow model.
Data exchange. Data exchange is the process of taking data structured under a source schema and transforming it into a target schema, so that the target data is an accurate representation of the source data. [1] Data exchange allows data to be shared between different computer programs. It is similar to the related concept of data integration ...
