Data that is processed in the cycle network is sent in one direction, from the Input nodes forwarding nodes until output arrives without a reversal of the data Nodes, or even in the same layer are connected.
Data processing networks will be sent in one direction from the Input nodes to output nodes passed through it without reversing or even Nodes in the same layer, they are not connected.
Data processing in the network will be sent in one direction from Input nodes forward gradually, until output nodes without reversal of information. Or even in the same Nodes layer no connection.
