How Does a Neural Network Mimic the Human Brain?

Like biological neurons, these artificial neurons form nodes. These nodes form neural nets. Like biological neural networks, layers are formed. In ANNs, however, these layers come in many varieties: first layer, next layer, node layer, convolutional layer, recurrent layer, input layer, an output layer, hidden layer, deep layer, the final layer, etc. These layers are used to form neural networks, and these networks also come in varieties: deep neural networks, deep-learning networks, convolutional neural networks (CNN), recurrent neural networks (RNN), etc.
