Binary codes

Binary codes !! if it is type your command text and converted to a computer machine language that is called Binary Codes....

The common basic two strings are used as 1's and 0's.....

Binary code has 8-bit character.....

Braille codes

Louis Braille was born January 4 (1809) in Coupvray, France....
An injury to his eye at age three, resulted in total loss of  vision. When he was ten, he entered the Royal Institute for Blind Youth in Paris, the world's first school for blind children. There he would live, study, and later teach......

When Louis was fifteen, he developed an ingenious system of reading and writing by means of raised dots......

Mr.Louis Braille accepted a full-time teaching position at the Institute when he was nineteen. He was a kind, compassionate teacher and an accomplished musician. He gave his life in selfless service to his pupils, to his friends, and to the perfection of his raised dot method, which is known today as Braille.......

Louis Braille died at age Forty-three, confident that his mission on earth was completed.........

MORSE CODES

Encode messages using two main elements....

1). Short beep ( . ) = basic unit of time (a dot is one unit)
2). Long beep ( - ) = length of unit of three short beeps (a dash is three units)
3). Space between parts of the same letter is one unit.
4). Space between letters is three units.
5). Space between words is seven units.

A character is made up of the combination of these...
EXAMPLES: 'S' = ( ... ) and 'O' = ( --- )

A word is made up of characters spaced out by a length of time equivalent to a long beep...
EXAMPLES: "SOS" = ( ...[space]---[space]... )
