Single instruction, single data stream (SISD):: A sequential computer which uses the similarity of two sections or four concurrent flow (or control) in the data flow on the number of education and architecture categories defined by Flynn. Multiple data, SISD architecture examples of traditional uniprocessor machines than PC (currently producing computers with multiple processors), or old mainframes.Single are instructions (SIMD) streams: a machine that many exploits against a stream of data guide to perform the operation currents are naturally parallel. For example, a number of processor or video card.

Many instructions, single data stream (MISD) run several commands in a single data stream. Sometimes the architecture is commonly used for fault tolerance. Heterogeneous systems to work on the data stream and should agree on the outcome. Multiple data, for example spacecraft flight control computer.Multiple includes instructions (MIMD) Streams: Various data on multiple independent processors during the execution of various instructions. Distribution systems are generally recognized as MIMD architecture, or a shared memory or distributed memory use.

Distributed memory MIMD machines, each processor has its own memory space. Each processor and processor memory has no direct knowledge. A message from one processor to another to be aired as data passed. Since there is no common memory, logic is not a major problem with these machines. It directly to each other is not advisable to combine a large number of processors. Each processor in a way, only to hit the large number of direct connections to avoid. This type of construction is inefficient because the processor from time to pass a message along the path a message can be delivered. Processor that may be important to simplify routing messages can be used to display time. System to reduce the time and Hypercube interconnection between two popular schemes are a waste of the Web have been developed.
