Morse Code is named after painter and founder of the National Academy of Design, Samuel F. B. Morse, who lived from 1791 to 1872. He, along with Alfred Vail, a machinist and inventor, and the physicist Joseph Henry developed the electromagnetic telegraph along with the code that assigns a set of dots and dashes or short and long pulses to each letter of the English alphabet. The first telegraph that successfully worked was produced in 1836 and made transmissions and communication possible over any distance. The first Morse Code message was "What hath God wrought?" and was sent from Washington to Baltimore in 1844. Morse Code is still used today in the military as a way of communication during harsh conditions due to universal means of communication. Experienced operators can copy text they received without the need to write what they receive, and when transmitting, they can easily converse at 20 to 30 words per minute. Morse Code can be conveyed using sound or light, which sometimes happens between ships at sea using lights. In emergencies, people use Morse Code to transmit distress signals when there is no other option. The standard international distress signal is ...---... (SOS). Since December 2003, Morse Code has even included the “@” symbol and it is a combination of a and c “.--.-.”. This is the first …show more content…
For languages not written with the Latin alphabet, other versions of Morse Code are used. There exists versions of Morse Code for the Greek, Cyrillic, Arabic and Hebrew alphabets. The Japanese Morse Code, known as Wabun Code, matches katakana syllables to specific codes like ア A “--.--”. The Chinese telegraph code maps Chinese characters to four-digit codes and then those digits are sent using standard Morse code. Korean Morse code uses the Standard Korean Alphabet Transliteration System, which was originally developed to allow the Korean language to be typed on western

When World War I and World War II broke out, communication played a vital role in the sequence and timing of everything that occurred on the battlefield. If communication problems arose, the results could be fatal. Front line units needed to know where their neighboring troops were and commanders could only control the troops if they had a reliable source of communication. Due to modern forms of communication being unreliable, the men who served during these wars used a method that dates back to ancient times. They deployed wartime messengers also known as “carrier pigeons”. Today, communications are more reliable and unmanned aerial vehicles (UAV) provide us with aerial surveillance.1
The urgency of communication was never much felt until the beginning and use of telegraphy. It was much easier to transmit and receive messages over long distances that no longer needed physical transport of letters.
Before 1919, four different men, from four different countries, created very similar ciphering machines all using a rotor or wired code wheel. Edward H. Hebern, United States; Arthur Scherbius, Germany; Hugo Alexander Koch, Netherlands; and Arvid Gerhard Damm, Sweden. Three of the four inventors were unable to complete their machines due to lack of funds. Only Scherbius, an electrical engineer from Germany, was able to complete his ciphering machine. He named the successful creation The Enigma.
Morse was a very friendly guy. Being a natural leader, he was a founder and the first president of the National Academy of Design, but was lost his campaigns to become mayor of New York or a Congressman. In 1832, while returning on the ship from another period of studying art in Europe, Morse heard a conversation about the newly discovered electromagnet and got the idea of an electric telegraph. He mistakenly thought that the idea of such a telegraph was new, helping to give him the go ahead and push the idea forward. By 1835 he probably had his first telegraph model working in the New York University building where he taught art. Being poor, Morse used materials like an old artist's canvas stretcher to hold his invention, a home-made battery and an old clock-work to move the paper on which dots and dashes were to be recorded.
The telegraph was developed in the 1830’s-1840’s by Samuel Morse. The telegraph or also known as the electric telegraph, would be a tremendous help during the war it
Communication in the nineteenth century involved physically moving from point A to point B. Most communication came in the form of handwritten letters. Some would be transported. If the letter was to be captured or never make it the sender may never find out and the message could be seen by the enemy leaving them with an upper hand. This remained so until the eighteen forties when Samuel F.B Morse sent the first code along a telegraph system. The message that he sent was “What hath God wrought?” which derives from the christian bible in the book of John, due to Morses religious affiliations.The telegraph is an arrangement of wires from the person sending the message and all the way to the person needing to receive the message. Along the wire the sender can put out electrical impulses that create an impression on a paper that is with the receiver. These impressions are an arrangement of dots and dashes, which could then be translated into letters and further into a message. Stations would be set up on either side of the wire where translators would wait and translate the incoming messages. They had charts the depicted what letter each arrangement symbolised. Not long after the war broke out many of the translators became so familiar with the code’s translations that they could read the message without the assistance of the guide. With this advancement people could send messages miles away and
Cipher is used in cryptography for the algorithm purposes. The algorithms include the encryption and the decryption which includes of well defined series of steps that can be followed as a procedure. But sometimes we get the word cipher in a non technical usage which means a code. But this was distinguished from codes when it came to the classical cryptography. To put this information clear, they were used to operate the substitution depending on a large code book that linked characters or figures to a word or phrase. For instance, the code UQJHSE could mean the same as the sentence “Proceed to the following coordinates.” But when it came to cipher, the UQJHSE could mean a plaintext or any other information that a sender would wish to transmit to a receiver (Gershaw, 1989). That was according to cipher, while when it comes to the encrypted form it was known as the ciphertext which had all the information concerning any of the plaintext but was unreadable mostly to the human or any computer without any mechanism to decrypt it. In any operation of the cipher, there must be a key which is always a piece of the auxiliary information. On the other way it can also be termed as a cryptovariable.
Communication. It is the basis of nearly all of our interactions with other humans in our lives. From the time we are born, we communicate the need to be held, fed, and changed. In our teens we explore new ways to communicate with other humans. As adults, we communicate with people of all ages when we go about our day. People communicate with their significant other and their boss. For people in the field of emergency medicine communication is an integral part of what they do. Emergency professionals communicate with patients, their families, other units in their agency, and those in other agencies. This paper will examine several points of communication that have been observed in the department that I work with and with related agencies. The use of ten codes in radio transmission, the
Cryptography started a long, long time ago with Julius Caesar. When he wanted only his people to know something he used cryptography. He did this by replacing A’s with D’s, B’s with E’s, and so on down the alphabet. This was known as "shift by 3", for obvious reasons. The Jewish writers also used a code of their own called Atbash. They did it by reversing the alphabet, they used the last letter of the alphabet in place of the first, the next to last for the second, and so on. Atbash is exemplified in the Bible,
The Morse code worked by transmitting electrical signals over a wire laid between stations. The code assigned letters and numbers a set of dots and dashes. The code was based on the frequency of use. Letters that were used quite frequently like “E” received a simple code, while others that were used infrequently such as “Q” received a more in depth code. The Morse code in the beginning was marks on a piece of paper that a telegraph operator would translate. The paper was quickly replaced by a receiver that allowed the operators to hear and interpret the code by simply listening to it. In 1843, Samuel Morse and his colleague Alfred Vail received funding from the U.S. Congress to set up and test their telegraph system between Washington, D.C., and Baltimore, Maryland. “On May 24, 1844, the first historic message was sent. Samuel Morse sent Alfred Vail the message of “What hath God wrought! (History.com,
He also used math to make the morse code. The machine was called a telegraph, which used a mathematical sequence to transmit messages faster, and across greater distances. The name of the mathematical sequence was Morse Code, which was named it’s inventor Samuel Morse. Morse Code uses short and long signals to create alphabetical messages, or words, to transmit messages. During Morse’s time, this benefitted people by allowing messages to travel faster than the old fashioned of horse and rider. Morse code nowadays is used mainly by military and military accomplices morse code is very popular in the american economy the morse code turned out to help produce TV, internet and radios that's crazy that's the way we use morse code and that is the way we benefit from
People in the present society have turned from the use of the old means of communication to the more advanced and technological ways of communicating. Technology has made it easier for people to communicate in a faster, efficient, and cost saving means through the introduction of the communication channels. The world has turned out to be the centre for technology with different technologies emerging daily as the people continue to develop from time to time to cope with the growing technology. The benefits of adopting the communication technology are explained in this article which shows why people do not function without technology.
Communication is an essential day-to-day practice in human life. In the present day, the communication is more important by the cultures and the nations than never in advance. In fact, language is the best means of the communication, and, therefore, it is necessary for the human interaction. In this globalized world, many people speak more than about one Language. The written language and expressing ideas and views are more effective in social cognitive cases of the communication. a writing system is a well-organized and systematic transfer of messages. It can be either for the people who can read or the people who are visually disabled (e.g. Braille Script). A writing system can have alphabets, logography, symbols or signs. There is standard
