## How computer convert Electric signals to binary and the reverse back binary to Electric signal...

I am unable to understand the hardware level working of computer because it work with electricity how it converted to binary and then electric again

Aug 3 2013: This question is about how an electromagnetic signal can become something that is either a 1 or a 0, that is a binary expression and its combinations. A normal, natural signal is what they call analogue, this means it is continuous, like a curve drawn on a page without any jumps or gaps in it. Now, take this curve and select parts of it, a point here, a point there and so on. What you have left is a bunch of points that look a bit like the curve you started with if you join the points together. This new set of points is a discrete version of the continuous curve, meaning made up of bits and pieces. This is what is done to a signal when it is converted between analogue to digital, the little bit of electrical circuitry which does this is called an analogue to digital converter, bits and pieces are selected from the original signal and saved as a bunch of numbers either a 1 or a 0 because this is the easiest way for a computer to work with and remember the information.
