A binary code converter is a program that lets users convert binary code into simple text. Binary code is code used by computers based on the binary number system, a number system in which there are only two states, on and off, symbolized by zero and one.
In binary code, each decimal number is represented by bits, a set of four binary digits. Binary uses the same rules as decimal number systems, with only the base being different. Decimal uses base 10, increasing by a power of 10 for each number moved one position to the left, while binary uses base two, each move to the left increasing the value by a power of two.
