Two parallel lines

In computing, the term parallel describes tasks performed simultaneously, on separate hardware. For example, with a DSP (digital signal processor), a signal's samples can be divided into equally-sized units, each processed in parallel on separate processors or cores. The individual "chunks" of the signal can be joined together in a final step.


The opposite of parallel access is serial, which is accessing or processing data one after the other.
