Flynn's taxonomy

Flynn's taxonomy is a classification system for computer architectures based on how they handle instructions and data. It has four main categories: 1. **SISD** (Single Instruction Single Data) - traditional single-threaded processing. 2. **SIMD** (Single Instruction Multiple Data) - processes multiple data points simultaneously, useful in graphics and data processing. 3. **MISD** (Multiple Instruction Single Data) - rare, where multiple instructions operate on a single data stream. 4. **MIMD** (Multiple Instruction Multiple Data) - supports multiple processors executing different instructions on different data, allowing for diverse tasks to be performed concurrently, ideal for modern computing.
