So Computers know only binary language, how does it understand to show for example letter “R” or number “3” on a Computer screen? Or how do impulses of power to make it 1 or 0 making computer understand to display certain things such as letters on the screen?

Answer 1

Binary isn’t just on and off. It can also be certain voltages.

For example, the computer has an internal clock that counts each binary digit. Each one is a few milli seconds in length.

A voltage over 5V would be a 1. Then a few milliseconds later if the voltage is below 5V the next figure will be a 0
