Neurons are inter-connected through nerve fiber called “axons” and “Dendrites”. The main role of axon is to transmit information from one neuron to another to which it is connected. Similarly, the represent a function, which modify the Sum value into 0, 1 or 0 to 1.  Actual output represent axon and the output will be received by neuron in next layer. Let us understand different types of
