Flynn's taxonomy

architecture A classification of computer architectures

based on the number of streams of instructions and data:

Single instruction/single data stream (SISD) - a sequential

computer.

Multiple instruction/single data stream (MISD) - unusual.

Single instruction/multiple data streams (SIMD) - e.g. an

array processor.

Multiple instruction/multiple data streams (MIMD) - multiple

autonomous processors simultaneously executing different

instructions on different data.
