neurons
Fiber optic cable
Those cells are nerve cells, the brain sends electrical pulses down and the electricity causes the heart to beat.
Of course they do. They are modified for that
Punched cards and electrical pulses quickly gave way to vacuum tubes and electronic digital computers.
Yes they do not
pulses
Cells are connected in a battery to carry out Red-ox reactions in order to generate electrical energy.
Nerve cells carry impulses in the form of electrical currents, they are insulated by myelin to avoid the electrical current from 'leaking out'.
Copper cable is the answer. Fiber Optic transmit using light and radio is frequency while wireless is wireless.
electrical pulses but not continuous
coherent light
Via electrical pulses sent through the earphone plugs. The pulses are then converted into sound by the headphones.
