Artificial Neural Network is a mathematical model, made in the form of
software or hardware, built on the principle of biological neural networks of living
cells. The neural network is a system of connected processors interacting with each
other. If you compare them with the biological analogue, you will understand that the
artificial network and the network of neurons are almost the same things. These
processors are usually simple (compared to a CPU used in a PC). Each network
processor either receives signals for processing or sent it to other processors. But if
they are connected in a huge network with controlled interaction, these «simple»
processors in large quantities can complete incredibly complicated tasks
