The binary encoder/decoder is a machine that converts alphabetical characters into binary numbers and back again. The alphabetical characters are encoded as long strings of binary digits, and the device can also automatically decode the string back to the original alphabetical string.
A binary digit is the smallest unit in a digital representation of numerals and is sometimes called a bit. It consists of two states: off (0) and on (1).
A binary numeral system uses base-2, meaning that each digit has two possible values: 0 and 1.
History of Binary Numbers
Binary numbers are a base-two system of counting and writing numbers.
Binary numbers date back to the invention of the modern binary system, which was invented by Gottfried Wilhelm Leibniz in 1689. Binary mathematics was first used commercially on punched cards for numerical calculations in 1801. Now, they are widely used in computers and other digital devices.
