Communication allows us to share important information and feelings with other people. With the development of certain technologies, we have been able to communicate with one another more easily. Telephones and the internet allow us to contact virtually anyone in a matter of seconds. We can talk to not only our neighbors, but also people all over the world. However, communicating with people on the other side of the world was not always this easy.
The development of communication began with speech. However, because speech was unable to convey some ideas, ancient people began making cave paintings to tell stories and record history. Cave drawings eventually led to the development of the alphabet and writing. Eventually, people began sending each other mail using postal services. Finally, telecommunication methods, such as Morse code and the telegraph, were developed. These electronic methods led to the development of even more advanced methods, such as email, instant messaging, and the telephone.
Telegraphs are systems that involve the transfer of a message without exchanging a physical object that contains the message. Some of the first telegraph systems utilized reflected light or smoke signals. Perhaps the most well-known telegraph system was developed by Samuel F.B. Morse, an American Artist. Morse created an electrical telegraph system capable of sending electrical impulses along a wire from one access point to another. The impulses he sent were known as Morse code. In time, electronic telegraphs were used both over land and across the ocean.
Morse code is a communication method that involves sending textual information using a sequence of clicks, lights, or tones. These signals can be understood by a skilled observer or listen without the use of any special technology or equipment. However, this communication system was most commonly used with Samuel Morse's telegraph. The international Morse code had signals for the 26 natural letters of the alphabet, along with some extensions for languages that used more than 26 letters. Transmissions were in all capital letters, as there was no signal for lowercase. There was also no signal in place for a question mark.
A ham radio is an amateur radio that utilizes the radio frequency spectrum for non-commercial purposes, such as emergency communication, self-training, wireless experimentation, or the recreational exchange of messages. The first ham radios were used at the end of the 19th century. However, the ham radio stations of today did not start to appear until the 20th century. Ham radio operations led to the development of today's radio stations, which broadcast everything from news programs to the newest music releases.
In fact, radio stations are one of America's fail safes in the event of national crisis. Many radio receivers are battery operated. This allows people the ability to receive transmissions without electricity. If a national disaster causes the electricity to fail, citizens can use these radios to receive valuable information from authorities.
Today, our communication methods have virtually no limits. Using new video telephone services such as Skype, you can talk face-to-face with an individual from the other side of the world in real time. With email and instant messaging, you can send textual messages to another person in a matter of seconds. You can also send documents, pictures, and videos using this technology. With cellular phones and text messaging, you can communicate with other people at any time of day, regardless of your location.
It took many years for communications to progress to the level of advancement we enjoy today. Though it may seem impossible to improve our communication methods, scientists and researchers are always looking for ways to make things better. As technology continues to evolve, it is likely that our communication methods will become even faster than they already are. The quality of video transmissions is likely to improve as well.

The history of communication is fascinating. From the development of the written word, to modern advances like the telephone and email, humans have relentlessly progressed their communication techniques. Throughout history a huge amount of energy and resources have been spent developing communication techniques and technologies, and even more energy and resources are spent using the technology to actually communicate with one another. Classically, communication has been of extreme importance to governments, military, and civilians alike. Humans seem to be dedicated to perfecting effortless, instant communication with anyone, from anywhere, at anytime.
