Morse code is a character encoding scheme used in telecommunications that encodes text characters as standardized sequences of two different signal durations called dots and dashes or dits and dahs. Morse code is named for Samuel F.B, an inventor of the  telegraph. 

The International Morse Code encodes the ISO Basic Alphabet, some extra Latin letters, the Arabic Alphabets and a small set of punctuation and procedural signals (prosign). Each Morse code symbol is formed by a sequence of dots and dashes. The dot duration is the basic unit of time measurement in Morse code transmission. The duration of a dash is three times the duration of a dot. Each dot or dash within a character is followed by period of signal absence, called a space, equal to the dot duration. The letters of a word are separated dots a space of duration equal to three dots, and the words are separated by a space equal to seven dots.

Morse code can be used as a sound also. In an emergency, Morse code can be generated by improvised methods such as turning a light on and off, tapping on an object or sounding a horn or whistle, making it one of the simplest and most versatile methods of telecommunication. The most common distress signal is SOS – three dots, three dashes, and three dots – internationally recognized by treaty. 

Morse code was used in the world war 2 for the first time. On the other hand, the Morse system for telegraphy, which was first used in about 1844, was designed to make indentations on a paper tape when electric currents were received. Morse's original telegraph receiver used a mechanical clockwork to move a paper tape. When an electrical current was received, an electromagnet engaged an armature that pushed a stylus onto the moving paper tape, making an indentation on the tape. When the current was interrupted, a spring retracted the stylus, and that portion of the moving tape remained unmarked. 

The Morse code was developed so that operators could translate the indentations marked on the paper tape into text messages. In his earliest code, Morse had planned to transmit only numerals, and to use a codebook to look up each word according to the number which had been sent. However, the code was soon expanded by Alfred Vail in 1840 to include letters and special characters, so it could be used more generally. Vail estimated the frequency of use of letters in the English Language by counting the movable type he found in the type-cases of a local newspaper in Morristown. Morse Code played an important role World war 2.

I and my friend Rupak love kinds of these codes. We are interested in these things.☺️
