Parallel Processing

Definition

Parallel processing is the ability of a biological system to process multiple pieces of information simultaneously. This concept is essential in understanding how organisms make quick decisions and react to their environments, as it enables them to evaluate various stimuli at the same time rather than sequentially. The efficiency gained from parallel processing plays a significant role in survival, allowing for rapid responses to complex situations, which is crucial in both nature and the development of artificial systems inspired by biological processes.
