Using a Tristate Buffer in an Inverter

A bus is just a collection of wires connected up to a number of different components or devices. A bus can connect components inside a processor, or it can also connect the processor as a whole with peripherals and other components on the mother board. When i have multiple devices that want to write to the same output wires, for example, all i have to ensure is that all of them are connected to the wires by a tri state bus. And then just enable one of those tri state buses corresponding to whichever of the, say, registers,. That way i can insure that only one of them at any given time is connected to the shed bus - I'll talk about the au in the next episode
