In order to best describe a local landline phone system it is best to understand some of the terms for the basic components of the landline telephone. A local loop is a loop of copper wire that allows current to flow from the telephone to the central office and back. It is a dual-wire physical interface that connects a telephone to the central office. The two wires are typically referred to as a twisted pair. This is how signal is sent through the telephone to give you the dial tone and to be able to talk. With the use of wires, this makes phone signal more clear than using a mobile phone and can help increase privacy.
The central office which is also referred to as the local exchange serves a group of subscribers (customers). All of the subscribers are physically connected to the central office through a pair of copper wires. All communications with the subscribers go through the central office. It is basically a wire system that is a building that houses inside plant equipment.
The local exchange carriers (LEC) are local telephone companies that provide service along with other LEC’s within a designated geographical area. One LEC serves multiple central offices.
The landline phone system also has long distance service which in the US is provided by an IXC. These carriers connect LECs together in different LATA or local access and transport area and sometimes within the same LATA. A POP or point of presence is the point where either the LEC or a long distance carrier meets another long distance carrier. It provides interconnection to the long distance carrier or interexchange carrier (IXC).

Cloud computing is a way to increase the capabilities of a device or add new capabilities or services without making any hardware changes to the device. An example is if you are traveling and along the way you stop and power on your laptop to check your email. Some of the key cloud computing services being offered today address data storage. Storing important information and files in the cloud can ensure that they are available for years to come and can be accessed globally wherever Internet connectivity is available. Through cloud computing a handheld device, such as a table computer, can access the Internet, check email, purchase concert tickets or monitor a webcam on another continent. Computation and software are also two other key areas of cloud computing.
Phones have come a long way from their beginnings. When the first phone was developed, a mere phone call took up to ten minutes just to connect. The calls made on this phone would go through a system of connections where the caller would have to state who they were calling and where the person lived. It would be many years later that a telephone would be created that made use of a dial, which made calling easier. In 1963, the first pushbutton telephone was distributed by the company, Bell Telephone. In 1983, the first cellular device, the Motorola DynaTAC 8000X, was created, which took the world by storm. Soon later, miniature computers were being put in these devices, allowing the user to browse parts of the web while on their cellular device. Yet we wouldn’t see a product that allowed us to browse the web, communicate with others, and let us store music and run apps, until 2007. (ht...
Long distance calling has become a vast market of sales and bribery. A majority of cell phone users have a long distance plan with there cellular package. A lot of college students have cell phones just to make long distance calls home to their friends and family. Depending on the time of day, a person in Fayetteville, Arkansas can call a person in Dallas, Texas for as little as 9 cents a minute. That is very cheap for that type of telephone call.

Thanks to the work of Alexander Graham Bell, the first telephone was created in March of 1876. In this case, the new device used electromechanical means to operate and was limited to only the wealthy. As time progressed, the first modern digital cell phone was introduced in the 1980s. In contrast to the first telephone, this new improvement was entirely electronic and included special digital features. Further, by 2010, three-quarters of Americans owned a cell phone. Voice transmission, camera and video functions, game and music players, and internet connectivity were all available due to the modern cell phone.
Global service coverage is in large demand, especially from businessmen who frequently travel. Linda Stern suggests in Newsweek to global travelers that they should “buy your phone and service from T-Mobile, AT&T or Cingular, the only three U.S. companies to use the internationally dominant GSM (Global System for Mobile communication).” Depending on the service provider, one may or may not get coverage in other countries. For example, Verizon customers enjoy phones that work in Latin America, while Cingular customers have coverage in Europe. Even better is AT&T Wireless, which offers “vast international coverage” or TMobile, another international carrier (Stern). Service coverage varies greatly by carrier, with some reaching many countries and others only small portions of a single country.
The wireless communications industry is perhaps matched only by the personal computer field in the rate at which new products and features are being introduced to the marketplace. What was once a novelty, used primarily by businesses, has now become commonplace among the masses. Today, cellular phones are owned by more than 114 million Americans according the Cellular Telecommunications & Internet Association reports . One of the advantages of having a cellular/mobile phone is that time spent commuting, caught up in traffic and traveling could now be productive. In addition, it increases the sense of security for people driving alone or concerned about vehicle breakdowns.
A communications network can provide many types of service. The most basic type of service is known as simplex. This service provides one-way communication. Examples of this type of service are TV distribution, and the transmission of burglar alarm messages.
The sound waves from the caller's voice cause the plastic disk to vibrate, changing the distance between the disks, thus changing the intensity of the electric field. These variations are translated into an electric current which travels across the telephone lines. The receiver of a telephone is composed of a flat ring of magnetic material. Underneath this magnetic ring is a coil of wire where the electric current flows. Here, the current and magnetic field from the magnet cause a diaphragm between the two to vibrate, and replicate the sounds that are transformed into electricity.
Truthfully, the list of benefits to having a telephone is infinite. I can quickly and easily call my parents in Folsom, my sister in Virginia, and my brother in Utah in just a few moments. I can leave a message on their voicemail, if they are not available, and wait for them to call me back. I do not have to get out a piece of paper and a pen, take the time to sit down and write a letter, spend money for a stamp and an envelope, drive to the post office to mail the letter, wait a few days for the letter to be delivered, and then wait a few days to receive a response. Additionally, if I am feeling extremely lazy or pressed for time, I can make it even easier to make contact by sending a group (to all of them at the same time) ...

Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life of society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b).
Since the invention of the cell phone by Marty Cooper in 1973 (Trowbridge), we have benefited from not being tethered to a landline. I have enjoyed the luxury a cell phone 's mobility provides. Getting an important a phone call from anywhere without being tied to one place can be extremely useful. I have had many phone calls about an emergency business need that I might have resulted in a deal gone bad if I missed the call while away from the office or home landline. Conversely,
The term telephone is founded by the greek root tele, which means afar and phone.. The telephone is a specific type of telecommunication that allows people to carry direct conversations over a period of time and at almost any distance. A quote from the article telephone describes how the telephone works. “The articulate speech is transmitted in a form of modulated electric current propagating along conductors or radio waves. The apparatus used for converting the verbal sounds into electromagnetic signals and vice versa is called a telephone set and is also commonly referred to as a telephone.” The telephone has been proven to be a valid way of communications and has been evolving ever since it was created. It has proven to be very valuable in the areas of business, government, science, public health, personal services, or social
Making a telephone call no longer should conjure up visions of operators connecting cables by hand or even of electrical signals causing relays to click into place and effect connections during dialing. The telephone system now is just a multilevel computer network with software switches in the network nodes to route calls get through much more quickly and reliably than they did in the past. A disadvantage is the potential for dramatic and widespread failures; for as has happened.
