Introduction:
Communication is a process where one sets out to convey a message to another person through the medium of words, gestures and / or pictures. The process of conveying the message is fulfilled only when the person receiving it has understood the message entirely. The cycle gives the process of communication.
Have you ever felt the messages you convey are not communicated properly or have you ever felt guilty of not conveying the message as it wants to be conveyed? If so it is because of your weakness towards communication skills. Apart from the basic necessities, you need to be equipped with habits for good communication skills, as this is what will make you a happy and successful social being. In order to develop these habits, you need to first acknowledge the fact that communication skills need an improvement from time to time. The only constant in life is change, and the more you accept your strengths and work towards dealing with shortcomings, especially in the area of communication skills, the better will be your interactions and the more your social popularity. Thus the present unit enables you to get a detailed picture of the need and importance of developing communication skills and feel confident and empowering to face any type of situation in life.

Early Communication Methods:
Communication has existed in various forms since man appeared on Earth. The methods, however, consisted of a disorganized set of signs that could have different meanings to each human using them. It wasn’t until three million years after man’s debut, around the year 30,000 B.C.E that communication began to take on an intentional, manufactured format. The most well-known form of primitive communication is cave paintings. The artistic endeavors were created by a species of man that appeared around 130,000 B.C.E, the Homo sapiens. The method involved creating pigments made from the juice of fruits and berries, colored minerals, or animal blood. These pigments were then used to create depictions of primitive life on the cave walls. The purpose of the paintings has been questioned by scholars for years, but the most popular theory states that the depictions were used as a manual for instructing others what animals were safe to eat.
Other forms of early communication existed, although they were less popular for a variety of reasons. Story telling was used to pass on important information in the days before the existence of the written word. However, since man still lived in separate tribes, this information could not be applied outside one’s own tribal community. Drums and smoke signals were also used by primitive man, but were not the most practical means of communicating. Both methods could attract unwanted attention from enemy tribes and predatory animals. These methods were also difficult to standardize.
Beyond writing: communicating through photography, code and sound:
By the 19th century, the world, it seems, was ready to move beyond the printed word (and no, people didn’t want to get back to advancing fire and smoke-generated messages).
People wanted photographs, except they didn’t know it yet. That was until French inventor Joseph Nicephore Niece captured the world’s first photographic image in 1822. The early process he pioneered, called heliography, and used a combination of various substances and their reactions to sunlight to copy the image from an engraving.
Other notable later contributions to the advancement of photography include a technique for producing color photographs called the three-color method, initially put forth by Scottish physicist James Clerk Maxwell in 1855 and Kodak roll film camera, invented by American George Eastman in 1888.
The foundation for the invention of electric telegraphy was laid by inventors Joseph Henry and Edward Davey. In 1835, both had independently and successfully demonstrated electromagnetic relay, where a weak electrical signal can be amplified and transmitted across long distances.
A few years later, shortly after the invention of the Cooke and Wheatstone telegraph, the first commercial electric telegraph system, an American inventor named Samuel Morse developed a version that sent signals several miles from Washington DC to Baltimore. And soon after, with the help of his assistant Alfred Vail, he devised the Morse code, a system of signal-induced indentations that correlated to numbers, special characters and letters of the alphabet.
Naturally, the next hurdle was to figure out a way to transmit sound too far off distances. The idea for a “speaking telegraph” was kicked around as early as 1843 when Italian inventor Innocenzo Vanzetti began broaching the concept. And while he and others explored the notion of transmitting sound across distances, it was Alexander Graham Bell who ultimately was granted a patent in 1876 for “Improvements in Telegraphy,” which laid out the underlying technology for electromagnetic telephones.
But what if someone tried to call and you weren’t available? Sure enough, right at the turn of the 20th century, a Danish inventor named Vladimir Paulsen set the tone for the answering machine with the invention of the telegraph one, the first device capable of recording and playing back the magnetic fields produced by sound. The magnetic recordings also became the foundation for mass data storage formats such as audio disc and tape.
Evolution from 18th Century till present:
The electric telephone was invented in the 1870s, it was based on earlier work with harmonic (multi-signal) telegraphs. The first commercial telephone services were set up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Alexander Graham Bell held the master patent for the telephone that was needed for such services in both countries. As with other great inventions such as radio, television, the light bulb, and the digital computer, there were several inventors who did pioneering experimental work on voice transmission over a wire, who then improved on Over several years starting in 1894, the Italian inventor Guglielmo Marconi worked on adapting the newly discovered phenomenon of radio waves to telecommunication, building the first wireless telegraphy system using them. In December 1901, he established wireless communication between St. John’s, Newfoundland and Poldhu, Cornwall in 1909. In 1900 Reginald Fessenden was able to wirelessly transmit a human voice.
In 1925, Kenjiro Takayanagi demonstrated a CRT television with thermal electron emission. In 1926, he demonstrated a CRT television with 40-line resolution, the first working example of a fully electronic television receiver. In 1927, he increased the television resolution to 100 lines, which was unrivaled until 1931.In 1928, he was the first to transmit human faces in half-tones on television, influencing the later work of Vladimir K. Zworykineach other’s ideas. The development of video telephony involved the historical development of several technologies which enabled the use of live video in addition to voice telecommunications.
In 1960 NASA launched an Echo satellite; the 100-foot (30 m) aluminized PET film balloon served as a passive reflector for radio communications. Courier 1B, built by Philco, also launched in 1960, was the world’s first active repeater satellite. Satellites these days are used for many applications such as uses in GPS, television, internet and telephone uses.
Computer networking is the biggest innovation in the world of communication that humans have yet to experience. Not only do computers help people to communicate in a variety of new ways, they also communicate with each other.
With home computers came the innovation of email. More convenient than a phone, email allowed people to contact individuals or groups anytime of the day or night without concern for time zones or long-distance calling fees. By the early 1990s, email was a must in the workplace. Today, it is still a much-used business tool.
Internet access became more common and more affordable as the 21st century neared. Many households began to view electronic communication methods like email and instant messaging as crucial to their everyday lives.
Social media may have had humble roots, but today many important political and social movements gain worldwide attention because of social media. Of course, it’s still a great way to communicate with friends and share information about your awesome family trip to the Grand Canyon!
The early inventors of the telephone would hardly recognize today’s Smart Phones. They’re more than phones; they’re mobile handheld computers that let users communicate with the World Wide Web just as easily as calling home. The mobile applications available on Smartphones make it possible to make travel plans, play games, build a business, or read an electronic book from almost anywhere in the world.
Where will technology take the field of communication next? Who knows? The wireless revolution has opened up more possibilities than even the most innovative thinkers of a decade or two ago could have predicted.
Conclusion:
Our communication methods so far. As we move into the future, our communications past tells us one thing for certain: As we continue to move forward as a species, new technologies will be there to support and inspire our evolution.
