Who realized the importance of the binary system in the computer field?

Answer 1

It was not suggested, per se. It was a de facto standard.

Computers operate on electrical principle. This means that there are only two states an electrical device can be on, at the simplest scale:

ON

and

OFF

This corresponds to 0 and 1 in binary. Transistors in the computer switch rapidly On and Off to create logical matrixes to store, transfer, and form data patterns in a complex process.

Non-binary computers do exist, but they are extremely unreliable, slow, and expensive. They are usually called 'Analog Computers'.

Answer 2

Nobody - the first computers were simple arrays of electrical switches - a switch can either be on (true) or off (false) - in binary, you use the figure 1 to indicate true and 0 to indicate false.
