The Invention of the Telephone and How It Has Changed Over the Years About 100 years ago, Alexander Graham Bell invented the telephone by accident with his assistant Mr. Watson. Over many years, the modern version of the telephone makes the one that Bell invented look like a piece of junk. Developments in tone dialing, call tracing, music on hold, and electronic ringers have greatly changed the telephone. This marvelous invention allows us to communicate with the entire globe 24 hours a day just by punching in a simple telephone number. It is the most used piece of electronic apparatus in the world. It is probably one of the most easy to use electronics available too. All you have to do is pick up the receiver, …show more content…
TELEPHONE NETWORKS If you have ever opened up a phone (do not try this at home, you might screw it up) you will probably see a PC (printed circuit) board. The board contains the needed electronics for the phone to work properly. In older models of a working telephone, this board may look like an electronic box. This board is called the telephone network. The telephone network's function is to provide all the necessary components and termination points (screw on or push on terminals). The components and the termination points connect and match the impedance of a handset (transmitter and receiver) to a two -- wire telephone circuit. Every component in the telephone has to be connected to the PC board. Usually, the board is the most reliable component inside the phone. All the delicate components are securely sealed by a metal enclosure. The PC board is a very fragile object and can be broken easily. If you look closely, you can see wires poking out of the board. The wires are soldered to the terminal legs. If you break one of those wires, man are you dead! TELEPHONE HOOK SWITCH Every time you talk over a line, you always need to disconnect. The most simple thing to do is to let the handset sit down. While sitting down, the handset can give force to a spring loaded operating arm, which is connected to a number

Communicating with others has always been important. There have been different forms of communication over the many years like messenger's, letters, telegraphs, and even radios. With all those ways of connecting to others, none have been good or effective enough to reach out to the people one would wish to talk to. Our society has changed in a huge way and part of the reason for that change is the telephone, and as we progress throughout the years technology becomes even more developed and more influential to our society.
Everyone has a cellphone regardless of age or wealth. This means it is impossible to escape the internet at home, school, or work, because it is in our very pocket. Cellphones are equipped with a variety of ringtones and jingles to catch our attention. These sounds can come at inconvenient times, but the cell phone user almost always reaches into their

Culture is what defined as the behavior and beliefs of particular groups of people. One of the most highly researched cultured countries in the world is, America. The concept that “America is a disposable society or the throw-away society” gives an insight an overconsumption and excessive production of items. “Out with the old, in with the new” is a cliché that defines America’s relationships with products. Americans justify their wastefulness by keeping up with the latest fad. People typically discard things that no longer have the same value as it once did. A perfect example of this, are cellular telephones. In the early and mid-2000’s, cellular telephones became a part of America’s everyday life. Cellular telephones are no longer a want
Before the telephone was invented, people struggled to communicate in many ways. They usually sent letters, although it took forever to send just one. Some used fire to communicate and sent out smoke signals. Others sent messages from hilltop to hilltop by raising or bringing down a semaphore towers arms. Also, lanterns were used to flash out a message in a code called Morse code. Morse code was sent by wires through the telegraph, but you had to know how to interpret the code in order to use it.
The history of voice communication technology begins in 1876 with the invention of Alexander Graham Bell’s telephone. In the 1890s, “law enforcement agencies begin tapping wires on early telephone networks”.[48] Remote voice communications “were carried almost exclusively by circuit-switched systems,” where telephone switches would
Cell phones are becoming a modern day necessity, to the point that they are a must have for every teenager and adult. Human beings are growing increasingly attached to these devices, depending on them more and more for their communication with other people, job duties, and other daily activities that they must accomplish.
The repositioning of the common house phone is a challenge. One option for the phone is to sell more landlines phones to developing world nations, but even there the growth possibilities are slim. There are small markets like Belize, but in most countries landline infrastructure is becoming limited. There are options, however, for repositioning the home phone in the United States, with some modifications to the technology. Lardinois (2010) notes that Americans under the age of 35 are unlikely to have a landline, as they use wireless devices for their computing needs. However, even wireless devices rely on hardwire connections to the router. The common house phone can be repositioned as a multi-purpose device, emphasizing a number of different unique functionality elements.
