The Invention of Morse code
Transmitting codes has been around for nearly two centuries, First using a code called Morse code when they needed to transmit vital messages from Washington D.C up to Baltimore within short periods of time. They would transmit these messages from a device called the telegraph during the Civil War period. The reason why it’s called Morse CODE is because only a few people in the whole world knew how to translate the message from a few dots and dashes to whole sentences and send a message back. The reason for this is because morse came up with a unique form of his own language using a designated code of dots and dashes.
The code assigned letters in the alphabet and numbers a set of dots (short marks) and dashes (long marks) based on the frequency of use. The code used the English alphabet but they would make the more frequently used letters into the less complex dots and dashes, such as E or A. While the Less frequently used letters such as D or Z got a lot more complex code of dots and dashes. Initially, the code, when transmitted over the telegraph system, was rendered as marks on a piece of paper that the telegraph operator would then translate back into English. Rather quickly. But then the operators became so good at translating the

Morse code has even been employed as an assistive technology, helping people with a variety of disabilities to communicate. Morse can be sent by persons with severe motion disabilities, as long as they have some minimal motor control. Morse code remains popular with amateur radio operators around the world. It is also commonly used for emergency signals. It can be sent in a variety of ways with improvised devices that can be switched easily on and off, such as flashlights. The following is the key they use today in order to translate across the
The Civil War, also called The War Between the States, was one of the bloodiest wars in American history. What made the Civil War such a massacre? The Civil War was such a bloodbath because the technological advances were so far superior to the tactics of the infantry, that the weapons virtually obliterated the soldiers. Soldiers would form lines known as a battalions. In these battalions, soldiers would basically march to their deaths. In addition to weapons doing so much damage, fortification on the battlefield was far more advanced than had ever been before. The Cheveau-de-frise was the main focus of armored fortification in the Civil War. This fortification consisted of 10 to 12 foot logs with large spiked-shaped, wooden stakes attached to the top of them. The Cheveau-de-frise would hold soldiers at bay while the opposing soldiers dismantled the battalion with cannons and rifles. Between the fortification and the weapons, humans did not have the slightest chance of survival.1
One of Great Britain’s most important naval developments was the founding of the top-secret Office of Naval Intelligence, better known as Room 40. Specializing in cryptography, “the science of writing in secret code” in order to hide sensitive information, Room 40’s cryptanalysts worked around the clock to break the secret code. Decryption is vital in secret transmissions concerning strategic war movements, as the enemy will be looking to intercept information concerning movements and positioning. Great Britain was aided in that the German Navy started the war with three primary codes, and within four months the British Admiralty possessed physical copies of all three of them.

The Black Codes were legal statutes and constitutional amendments enacted by the ex Confederate states following the Civil War that sought to restrict the liberties of newly free slaves, to ensure a supply of inexpensive agricultural labor, and maintain a white dominated hierachy. (paragraph 1) In southern states, prior to the Civil War they enacted Slave Codes to regulate the institution of slavery. And northern non-slave holding states enacted laws to limit the black political power and social mobility. (paragraph 2) Black Codes were adopted after the Civil War and borrowed points from the antebellum slave laws as well as laws in the northern states used to regulate free blacks. (paragraph 3) Eventually, the Black Codes were extinguished when Radical Republican Reconstruction efforts began in 1866-67 along with the passage of the Fourteenth Amendment and civil rights legislation. The lives of the Black Codes did not have longevity but were significant. (paragraph 3)
During the Pacific portion of World War II, increasingly frequent instances of broken codes plagued the United States Marine Corps. Because the Japanese had become adept code breakers, at one point a code based on a mathematical algorithm could not be considered secure for more than 24 hours. Desperate for an answer to the apparent problem, the Marines decided to implement a non-mathematical code; they turned to Philip Johnston's concept of using a coded Navajo language for transmissions.
The Civil War was the bloodiest, most devestating war that has ever been fought on American soil. It began on April 12, 1861, at 4:30 in the morning. The main reason that the war was fought was because Southern states believed that they should have the right to use African-Americans as slaves, and the Northern States opposed that belief.
The sender would type the message in plaintext (not encrypted) and the letters would be illuminated on a glass screen. With the press of each typewriter key the rotor would shift 1/26 of a revolution giving each letter a different encryption each time, which made the code so difficult to crack. Due to the complexity of the code the enigma became very useful for the Germans for radioing messages to u-boats. The cipher was finally broken when the British were able to capture some key documents from a German warship.
Every war, though happens for a reason and bring a better change, is often gruesome. The Civil War broke America in two groups and, at the time, was the war with the most casualties and injured men. As the fight to preserve the Union progressed, so did a number of other areas, such as weaponry and artillery. The advanced technology produced through the Civil War assisted in increasing number of casualties. The North was more fortuitous than the South in multitudinous ways. One of which includes the fact that their industrial society allowed them to produce a larger amount of weapons of a higher quality. One of the major reasons the Union triumphantly defeated the Confederate army was because of their more superior types of weapons.
The American Civil War was one of the deadliest wars in American history, resulting in 620,000 casualties of soldiers and undetermined number of civilian casualties. Southern slave states declared their withdrawal from United States and formed the Confederate States of America; also know as “The Confederacy.” Northern twenty states free of slavery and five slave states in north came to knows as the Union. Many strategy and tactics were used during the American Civil War. In order to understand the military strategy and tactics of Union and the Confederacy, one must understand the manpower each side had, previous war experience of the commanding officers on both side, and using rivers and railroad to their advantages.
The majority of speculations regarding the causes of the American Civil War are in some relation to slavery. While slavery was a factor in the disagreements that led to the Civil War, it was not the solitary or primary cause. There were three other, larger causes that contributed more directly to the beginning of the secession of the southern states and, eventually, the start of the war. Those three causes included economic and social divergence amongst the North and South, state versus national rights, and the Supreme Court’s ruling in the Dred Scott case. Each of these causes involved slavery in some way, but were not exclusively based upon slavery.
...op a Navajo code. The Navajo language seemed to be the perfect option as a code because it is not written and very few people who aren’t of Navajo origin can speak it. However, the Marine Corps took the code to the next level and made it virtually unbreakable by further encoding the language with word substitution. During the course of the war, about 400 Navajos participated in the code talker program. The navajo helped end the second world war.
In the Barcode Tattoo, the idea was founded by a new system of belief. The tattoo had started in Europe and Asia, and then became required. It had started spreading to America slowly after. Global-1, a company that took over the postal industry after the crash of USPS, gives out the barcodes at their local offices, and endorses the idea. The idea of the barcode is so that
The most important thing when interacting with other human beings is being able to communicate one another. People’s first mechanical way of communicating was with the invention of the telegraph, which was at first run by gas. It wasn’t until 1836, when Samuel F.B Morse, Alfred Vail, and Joseph Henry invented Morse code that our civilization had would be able to electronically communicate. Soon after, the first telephone was invented by Alexander Graham Bell which allowed people to vocally converse electronically from miles away. The invention of the telephone was then modified and eventually converted into a mobile cellular phone by Martin Cooper in...
Codes have been around for centuries ranging from wax, invisible ink, Morse code, the Enigma used by the Germans during World War II and now steganographic. Steganography is the latest form to insidiously hide information over the Internet without a trace of a file being altered. You are able to hide messages within images, voice or music. Steganography is an ancient method of hiding messages. Today messages are hidden in images and music. Steganography can be traced back to the ancient Greek who would write messages on tablets and cover them in wax. This made the tablets look blank and unsuspicious (Kolata, F4). Citizens of ancient civilizations would tattoo messages on their shaved heads. They would then let their hair grown in and travel across enemy lines to deliver the message (Seper, G1). During World War II the Allies placed a ban on flower deliveries with dates, crossword puzzles and even report cards (Kolata, F4) for fear of a message being hidden with in. Steganographers first alter their data by using encryption and then place the image into a pre-select image. Steganographers look for a piece of code that would be the least significant and look the least altered to the human eye (Kolata, F4), being as inconspicuousness and random as possible. This makes the messages undetectable unless you knew that there is a message hidden and you were able to crack the code.
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
