Computers understand only binary language.
But, we are humans. We are living beings. We function differently. However, our brain functions in some way similar to a computer. The neurons together forming a brain have some fluids inside them. Specific proportions of those fluids are responsible for a state of a neuron. I guess this mechanism is similar to what we see in a computer. Signals, electrical, are transferred in the transistors. So, there lies some relation which we can establish between a human and a computer.
