What is the significant of binary system in computer system?

Answer 1

Binary is a number system (just like the decimal system is a number system) that allows all numbers (and thus anything that can be represented by numbers, such as text, pictures, videos, etc) to be represented by only two distinct numbers: 1 and 0. This simplifies computers so that they only have to be able to represent those two numbers, and thus they can be represented by a high voltage and a low voltage, respectively. If a more complex number system were used, computers would need to be so much more complex, so much more precise (and they already are VERY precise), that what we have with computers today would be virtually impossible.

So, the binary system made computers the way we know them possible.

Answer 2

Since almost the beginning of computer technology, the data/information read, used, and created by a computer is represented in binary code (0's and 1's). It is a simple way to universally represent data. As computer technology becomes more advanced, processor companies, such as Intel and AMD, develop simpler and faster "pipelines" for digital data (represented by binary code).
