Parallel processing is the ability of the brain to simultaneously process incoming stimuli. The brain is the center of the Nervous system in animals All Vertebrates and the majority of Invertebrates have a brain This becomes most important in vision, as the brain divides what it sees into four components: color, motion, form, and depth. In Psychology, visual perception is the ability to interpret information from Visible light reaching the Eyes The resulting Perception is also In Physics, motion means a constant change in the location of a body Distance is a numerical description of how far apart objects are These are individually analysed and then compared to stored memories, which helps the brain identify what you are viewing. In Psychology, memory is an organism's ability to store retain and subsequently retrieve information The brain then combines all of these into one image that you see and comprehend. This is a continual and seamless operation.
The advantage of parallel processing is that it allows the brain to simultaneously identify different stimuli and allow for quick and decisive action.
This is one of the reasons that the human brain is much more powerful than the computer. The human brain controls the Central nervous system (CNS by way of the Cranial nerves and Spinal cord, the Peripheral nervous system (PNS A computer is a Machine that manipulates data according to a list of instructions. While a computer is a million times faster than a human's neural network, it is the fact that we have a large number of processors compared to computers. Traditionally the term neural network had been used to refer to a network or circuit of biological neurons. As Donald Hoffman said (1998, p. xiii) "You can buy a chess machine that beats a master but can't yet buy a vision machine that beats a toddler's vision. " The technology known as computer vision, however, allows computers to recognize objects visually. Computer vision is the science and technology of machines that see
Parallel Processing in Computers
The simultaneous use of more than one CPU to execute a program. Parallel computing is a form of computation in which many instructions are carried out simultaneously operating on the principle that large problems can often Ideally, parallel processing makes a program run faster because there are more engines (CPUs) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several. There are even computers with thousands of CPUs. With single-CPU computers, it is possible to perform parallel processing by connecting the computers in a network. However, this type of parallel processing requires very sophisticated software called distributed processing software.
Note that parallel processing differs from multitasking, in which a single CPU executes several programs at once. In computing Multitasking is a method by which multiple tasks also known as processes, share common processing resources such as a CPU.
Parallel processing is also called parallel computing.
