Flynn's taxonomy

Flynn's taxonomy is 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.
