The Effect of Electronics on Communication Electronics has played a major part in communication and the developments of it. The first ways of communication not by just talking were the uses of cans and a piece of string. This worked by the vibrations of the voice vibrating down the string and into the other person’s can. The next major development was the invention of telephones. The first telephones were large and ugly with large numbers and were difficult to hear, and the switchboards were done manually by women and children. The next part of communication was the internet. This was first brought into use by the armies who wanted to move data from one computer to the other without the use of disks etc. Next was the mobile computer, or the laptop. The first model of these has a small screen which was black and white and was very slow and also expensive. They were only really used by businessmen and rich people. Now they have changed and have large colour screens and are of comparison in speed to that of desktop computers. The next development was that of mobile phones. It was at first thought never to take off with the large models, which needed a long charge for not much talk time. This changed when the phones which looked good and were small were introduced. Also the idea of text messaging took off with many people using it. Recent developments in electronics in communication have been that of smartphones which have tried to incorporate a phone, a camera, a video recorder, a planner, a games console and a computer all into one. These are good in theory but normally when all these features are packed into a phone, the phone i... ... middle of paper ... ... The negative part of programs such as KaZaA and eDonkey is that they are being used to transfer files such as music, films and software costing the companies that produce the media millions. Broadband is also helping the file sharers as with standard 512k/s broadband they can download nearly 10 times as much data as a 56k/s dial-up connection. Also the compression codecs for movies and music means that they can be made a lot smaller with the same high quality being preserved. However some record companies have been releasing “fake” music files into the sharing domain. Normally these are 30 seconds of the song, which then fade into nothing for the rest of the song. Other companies, for one Madonna’s have released her swearing and screaming about how she hates file sharers and how they are costing the industry millions.
Through phones we are able to call upon knowledge at any time but may people do not look at the drawbacks phones take from society. As the technology is released it is impossible to turn back the tides of time the culture must adapt and grow with it over time. Though phones have been invented to create an easier means of communication it is actually having an adverse effect of culture throughout the world. In many places people are growing more inept of having personal communication preferring to have conversations through any digital means such as text messaging, emailing, and snapchat. The growing inability to have one-on-one conversations is easily visible as you can see a couple on a date having an e-date if you go to a café such as Starbucks. The ability to write is also decreasing in schools due to the growing use of SMS language on cyber communication. With interaction both verbal and written on the down slope what Postman lays out in front of us in Technopoly is sadly becoming or has become
The tools of communication have long served a single purpose, that of transmitting information from people to people. Direct communication was long ago realised with sign language and speech, but when people spread out, a kind indirect communication was needed. Thus we created (or rather, hired) the messenger. (Necessity is the mother of invention.) This evolved later into a postal service, connected around the world by a network of synchronised offices of a similar nature. For a long time, indirect communication was the only way to communicate over long distances. Once the telegraph came along, however, people were able to instantly communicate information over long distances. This evolved somewhat into the telephone, which spawned the radio and television. As these were developed, the efficiency and clarity of these transmissions improved, and this allowed the world to know what was happening anywhere else in the world at any given time.
Morse code and the telegraph were ingenious yet simple. Operators used a simple method of dots and dashes for letters and numbers. When the Morse Key was pressed the electric circuit was open and when released the electric circuit was closed. The electrical current traveled through the wire to a printer device that printed a tape of the code message which an operator would translate. This simple solution to communicating long distance has improved and evolved into a newer technology, the packet switch. The single signal wire has evolved into fiber optics. Communicating one at a time has evolved into mass communication.
As the telephone was a faster and less tedious way of sending information, more people, who formerly used telegraphs, began to use it instead. Telegraph companies were losing business, and fast, to the object you and I can’t live without. The telephone’s gaining popularity was eventually going to end the use of the device that changed the world before, its predecessor, the telegraph.
The nineteenth century was a very prolific era of discovery in electrical knowledge and technologies that laid the foundation for modern electrical communication. During this period of time the foundations of modern electrically based technologies were discovered. The nineteenth century began with a debate between Luigi Galvani, and Alessandro Volta regarding the source of electricity in Galvani’s famous frog experiment. These debates lead to the invention of the battery by Volta, and the invention of Volta’s. Volta’s discoveries would lead the way for Ohm’s law several years later. However, before that discovery was made Hans Christian Ørstead discovered electromagnetism, which was then used by André Marie Amperè to show that magnetism is electricity. Following the publication of Ohm’s law, Faraday would publish his findings on induction in the 1830’s. That same decade the DC generator, and transformer were invented, and followed in the 1840’s by the invention of AC generator. Communications technologies advanced at an incredible pace. Sömmering would design the first multi-line telegraph, and Morse would perfect this into a practical single wire design. The work of Charles Wheatstone in telegraphy and Heinrich Hertz in wave theory, paved the way for modern communications. Alexander Graham Bell invented the telephone in 1876. Èdouard Branly would make the contribution of a detector that allowed for the invention of the radio. Guglielmo Marconi and Alexander Stepanovich Popov would develop the first radios. From the invention of the battery to the first intercontinental telegram transmission, the advances in electrical technologies in the 19th century made possible the technological boom of the 20th and 21st centuries in comm...
Smart phones have dramatically changed the way we communicate. I know for certain that after seeing my friends during the day that when I get home I can immediately text them or snap chatting or any of the ways we communicate. I can’t imagine living in a world without being able to communicate with my friends across the room or across the globe at the click of a button. Sitting in my room I can check the news, play a game and talk to my friend in America all at the same time. The technology has advanced so much since the first iPhone. Along with other smart phones they have changed the way we communicate because we can just pick up the phone and talk to someone and you can text a question or facetime them. Smart phones have changed the world because at the tips of your fingers anywhere you can check the weather, watch a video, listen to music, take a picture, get directions, check the time, get information from the internet and watch your favorite TV show.
Technology has become an element which is as important as food to people nowadays. Everything that we do in our daily lives requires technology from complex machineries to something as simple as turning on a light bulb. The amazing thinkers behind these life-changing innovations include Alexander Graham Bell; the telephone inventor, Thomas Alva Edison; the man who lit up the world and many more. Have you ever thought why we say ‘hello’ every time we answer a call from the telephone? It is because Bell’s wife was named Hello! Over the years, the evolution of technology has come a very long way as time flies. There is massive difference between the olden days and modern time due to technology. Last time, people find entertainment just by staring into the skies and nature but now we get to laugh over graphics on a glass screens while lazing on our favourite
The telephone is one the greatest inventions of all time dating back to 1876. It has made a powerful impact throughout history and changed the way we live today. Now most communication is done over social media and cellular communication. Throughout the first stages of the telephone, Alexander Graham Bell discovered “That a thin metal sheet vibrating in an electromagnetic field produces an electrical waveform.” (The 50) This process allows one to communicate without the need of face to face interaction. Thus eliminating the need for ancient communication methods such as the telegraph. Although Alexander is the inventor of the telephone he denied having one in his workplace fearful it would distract him of
Many inventions revolutionized society and one example is the telephone, which was introduced to society in 1876. The inventor, Alexander Graham Bell developed this idea and the telephone made him famous because communication would never be the same after the development of the telephone. The telephone made an incredible impact on society. The impact could be seen through the quickness of communication, business, easier communication in wars, and some negative effects too.
There are several forms of communication in this world, since then until now that has revolutionized technology. We no longer have to use hand signals, smoke signals, sending messages via pigeons, or travel a long distance to talk to relatives or friends. We as a society have come a long way from all of that to what we have today. Just as some believe in the Big Bang Theory, the cosmic expansion that caused creation. We can relate this to technology. We have a Big Boom in communication technology from the time of creation all the way to today. Today, I will be sharing with you three of those items that have greatly impacted how we communicate through a much easier and time saving process. I am going to take you on a journey of the mail,
Technology greatly impacts on human continuation by offering new risks as well as new benefits to human lives. It is worth mentioning here that technology is always transforming and it affects every part of people lives either in a positive or negative way. In every field of human life, a number of technological devices have been developed in the last few decades. Among them, mobile phone is known as one of those technologies that has brought the greatest satisfaction into the human lives. Undoubtedly, mobile phones have become a great part of our society.
Cell phones have immensely changed the way people communicate today. A cell phone can be all a person need for interaction. From a cell phone, a person can make calls, send text messages, emails, and send and also receive directions, buy things online, do online banking, listen to music and much more. Since someone can do everything with one device, there is no longer a need to go around with multiple devices about. Greek hydraulic semaphore systems were used as early as the 4th century. The hydraulic semaphores, which functioned with water filled containers and visual signals, functioned as optical telegraphs. However, they could only apply a very limited range of pre-determined messages, and as with all such visual telegraphs could only be deployed during good visibility conditions. Experiments on communication using electricity was carried out in 1729 but was not successful. The experiment was proposed by William Fothergill Cooke. In 1837, William invented a practical electric telegraph which entered commercial use in 1838 (J. B. Calvert, May 2004). The first telephone was invented in 1878 by Alexander Graham Bell. He experimented with a ‘phonautograph’, it is a machine shaped like a pen that can draw shapes of sound waves on smoked glass by tracing vibrations.
Most innovations have are two sides, the good side and the bad side and the cell phone is no exception. Many people find it difficult to believe that there was a time that cell phones did not exist. Letters back then were used to pass messages across before the telephones were introduced. Initially, telephones were used only to call people, who would receive the call only if they were near the receiver. Then the cell phones were introduced. They could receive or make calls and text messages to most parts of the world. With the cell phones, it was easier to write a text message than to hand write a note as it was before (). With time, the level of use of cell phones has gone up with more features being introduced. The cell phone technology is a double-edged innovation that inevitably changed as both positively and negatively socially.
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.
At the dawn of the information age, to be young, as Wordsworth said in another context, is very heaven. Getting to know what goes inside computers, the engines of the Information Technology revolution, and knowing how to work with them enables one to understand the technology that makes it all possible. Understanding this, I chose to do my undergraduate study in Electronics and Communications engineering.
