The digital world is binary(da_what3)
What is Binary?
Binary is a scheme of numbers that only has two possible values for each digit: 0 and 1. The term also describes any encoding/ decoding system in which there are only two possible states. In digital data storage, memory, communications, or processing the 0 and 1 values are sometimes called "low" and "high" or "On" and "Off".
The digital world is represented in binary, but hexadecimal, which is compatible with binary and more easily understood by people, is commonly used. Like previously mentioned, binary uses only the numbers 0 and 1. However, in some cases L/H is used as a counterpart to 0/1 notation.
In order to indicate which base is used, d(decimal), b(binary), and h (hexadecimal) are added to the end of the number.
Base 10=Decimal Base 2=Binary Base 16=Hexadecimal
Example
11d（11 in decimal）、11b（3 in decimal）、11h(=17d)

Important Numbers to Remember
Increasing a binary number by one digit can double the value.
The values in red are often used by A/D and D/A converters.

What Are Bits?
A single binary digit, which is either 0 or 1, is also referred to as a bit.
