How is data represented in the computer?
Digital devices represent numeric data using the binary number system, also called base 2.
The binary number system only has two digits: 0 and 1.
No numeral like 2 exists in the system, so the number “two” is represented in binary as 10 (pronounced “one zero”)..
Computers don't use ten digits (or denary, also called base 10).
They run using electrical components called transistors which can be either turned on, or turned off.
We need a system that can represent these two values and conveniently we can use binary, or base two.
Binary only has two digits, a 0 and a 1.
