Question

how a base value is determined in computer​

Answer 1

Explanation:

In a computer, it is easy to represent information digitally, using either the presence or absence of an electrical potential. Your computer's processor is an enormous array of transistors--literally billions of them--which are basically electronic switches that turn on or off. Your computer's memory stores information using either the presence or absence of an electric charge. It is difficult and cumbersome to represent information using multiple values of electric current (say, 1 volt for a 1, 2 volts for a 2, 3 volts for a 3, and so on). Such analog computers were built, very early in history, but digital computers quickly surpassed them in performance.
