How to Implement Logic Gates in Computers

A logic gate is in turn made up of transistors. A transistor is just a switch that can either be switched to off or on, depending upon the voltage of the gate unit,. The voltage that i apply to that gate region determines whether the switch goes on or off. All these operations are implemented using logic gates connected by wires. By applying the right voltages to the right gates at the right times, i am able to activate them in a way that computes functions that i need. For example, and gates or invertes or decodes, which take in an address and produce and activate the output of one particular address line. Then it hands back, once it's done with
