Asymmetric

Updated: 08/03/2018 by Computer Hope

Asymmetric may refer to any of the following:

1. In general, the word asymmetric describes the lack or violation of symmetry (being the same when reflected across a distinct line). For example, a broadband Internet connection that is an asymmetrical connection is a connection that has different download and upload speeds.

2. In computing, asymmetric multi-processing refers to using multiple processors in a way that does not treat all processors equally. Asymmetric processing was an approach used in some of the first multi-processor systems because it is an affordable way to increase computing power. In contrast, modern multi-processor systems use SMP (symmetric multi-processing), in which all processors have access to all the same resources, with none of them treated differently.

In asymmetric multi-processing, processors take care of entirely different tasks. For instance, one CPU might work operating system tasks while another might handle programs run by the user. These processors might share access to the same memory, but fulfill entirely separate computing purposes.
