They dont have to use zeros and ones. It can be anything that are oposite.

Computers use binary numbers. This is ones and zeros.

True?
So that we can write computer programs in a manner that humans can read. Computers "think" in one and zeros, and in a very logic based, linear fashion. Programming languages are a bridge between the way people think, and the ones and zeros that computers use. Programming languages also help programs think in a step by step fashion like computers do.
Binary code is the basic language of "ones" and "zeros" with which computers operate. It is useful to people working in computer science to know how to convert between binary and decimal notations, for various reasons involving basic fundamental operations of computers.
Computers DO use analogue methods to transfer information.Modems, for example (short for "Modulator/DEModulator") use either frequency shift or phase shift to transmit information.Your monitor, even if it is a digital monitor, is using light to transmit information to your eyes, which is an analogue medium.Even your wireless connection uses frequencies (analogue) representing ones and zeros to your computer; where the frequencies are converted back to ones and zeros by the wireless card.
It is known as the binary code.
you can write the ones and zeros on paper as 1 or 0you can write the ones and zeros on paper as a row of triangles and squaresyou can paint the ones and zeros on canvas as a row of small dots and large dotsyou can show the ones and zeros by placing a row of 2x4 boards horizontally or verticallyyou can indicate the ones and zeros by using a row of red and green colored flagsyou can indicate the ones and zeros with a row of electric lights that are on or offyou can record the ones and zeros magnetically as flux reversals or no flux reversalsyou can record the ones and zeros magnetically as clockwise or counterclockwise magnetizationetc.
