Binary numbers are closely related to digital electronics. With digital electronics a ‘1’ means that current / electricity is present and a ‘0’ means it is not present. The different parts of a computer communicate through pulses of current (1s and0s).
As we all know, computers can calculate complex equations and perform complex mathematics at lightening speed. Calculating using only 1s and 0s is called the BINARY SYSTEM. Although a computer will only process 1s and 0s there comes a point when the 1s and 0s have to be converted into our usual decimal numbers that we are familiar with._
