Question

why does computers language only have 0 &1?

In: 8

Answer 1

The 0 and 1 mean that a transistor is either off or on.

A CPU is made of billions of little switches that are all either off or on depending on the instruction and that’s what makes the calculations using things called ‘logic gates’

Trying to make it have more values like ‘Off, Low, Medium, High’ etc… is very difficult and there’d be constant confusion and misreading of the voltage, especially now with things so tiny.

So ultimately all computing language comes down to which transistors are on or off
