1. Parallel computing or parallel computing is relative to serial computing.
2. It is an algorithm that can execute multiple instructions at a time. Its purpose is to improve the computing speed and solve large and complex computing problems by expanding the scale of problem solving.
3. Parallel computing can be divided into temporal parallelism and spatial parallelism.
4. Temporal parallelism refers to pipeline technology, while spatial parallelism refers to the concurrent execution of computation by multiple processors.
