Voice vs. Data
Cell phones- wireless phones served by a cellular telephone system broken into small geographical areas. It’s a two-way that carries full duplex conversations. Cell phones have evolve from 1G, which carries information similar to the way fixed line phones transmit voice from subscriber to central office to 4G network for fast access of the internet. It uses both voice and data networks. (woodward, 2012)
Landline phones – Initially landline phones started as a device to transmit voice. While it didn’t seem like a good choice to transmit data, however, for many years it was subscribers’ only choice for transmitting data.
SMS/Text messaging –The short messaging services (SMS) still works on voice networks. It is the mechanism of sending short messages over mobile networks. The message from the sending mobile is stored in a central SMS center which then forwards it to the destination. SMS can be no longer than 160 characters. (http://www.wirelessdevnet.com)
Fax Machine – short for facsimile machine is a device that can send or receive pictures or text over a telephone line. It works by digitizing the image into grids of dots. The dot is either black or white representing on or off. (http://www.webopedia/TERM/fax-machine.html)
VOIP (voice over IP) uses VOIP technologies for placing and transmitting calls over an IP network such as the internet, instead of the traditional public switch telephone network (PSTN). With VOIP analog voice calls are converted into packets data. With VOIP calls can be made to land lines or cell phones as well as computer to computer.
Skype/Facetime – are VOIP technologies that used both data and voice networks. This communication works through the internet. Instead of sending signals via a PTSN network, VOIP applications usually uses SIP(session initiation…...

...Unit 7. Assignment 1. Refraction, Reflection and Optics Refraction: The most common real life example used when discussing refraction is a straw in water. When a straw is placed in a glass of water and viewed from the side, it appears to be broken or bent. This is due to the difference in the refractive indices of air and water. Since water is denser than air, the straw appears to bend as the light it reflects is slowed by the density of the water. This phenomenon also makes submerged objects, such as fish look closer to the surface than they actually are. Another common example is a rainbow, where sunlight is refracted by raindrops. Sunlight consists of a mixture of different wavelengths, or colors, of light, with blue, for example, having a shorter wavelength than red. When this light passes through raindrops, the shorter wavelengths are bent more than the longer ones, splitting the light into its different colors. Reflection: Pretty much everything you see could be considered reflection. The fact we can see is due to light reflecting off of objects and into our eyes. A good example, I guess, is the moon. When it glows at night that is just light from the sun reflecting onto the Moon's surface, and bouncing back, giving it that glow. Degradation of signal strength in fiber-optic transmission. The main factors that affect this is number of connectors, splicing, Quality of Fiber / connectors, also not using an Attenuator according to the distance, or using dirty......

...Networking Unit 1 Assignment 1 Cell phones – Cell phones use data networks to communicate over radio frequencies. The frequencies that they use are also shared with television, Bluetooth, and Wi-Fi. Landline phones – Landline phones use voice networks only because they do not need as much speed as anything else. Normal house phones use approximately 10 MB/s which is all that voice networks handle. SMS/Text messaging – Text messaging uses data networks because they can also be sending media like pictures and video. The other reason that I believe that text messaging uses data networking is because it is faster. Fax machines – Fax machines use voice because they only transmit exactly what is on the paper. It is not being transformed into little packets and sent over the internet to another place; it is just sent from one place to another through the phone line. Pagers – Pagers use the same as cell phones and that is data networks because it is wireless, and does not have to be plugged into anything. Pagers are not that common due to the cell phone industry growing swiftly. VOIP – VOIP as it says in the name of it uses a data network. It uses IP for talking so that the communication is more secure and not many people can tap in as easily as people can over regular phones. Skype/Facetime – Skype and facetime both use data networks to communicate because you are sharing video with somebody else.

...are others who are always on the go and would like to explore the possibility of cellular networks. The purpose of this paper is to compare and contrast several attributes of purely fixed line networks vs. having a purely cellular network. Fixed line networks have been and will continue to be a huge industry because the major players provide the backbone. For this reason alone, the company should not expect to pay outrageous prices for equipment. From a security standpoint, fixed line networks are less susceptible to wire sniffing attacks and more secure than cellular networks due to the fact that the hacker would have to gain access to the fixed line network rather than simply intercepting the transmission from a cellular network. While fixed line networks are considered the norm for most companies, they do have limitations. A company which adopts a purely fixed line network will not have the capability to send or receive data unless the user is physically inside the company. This would prove to be a major drawback to companies who have employees who travel to other cities to attend meetings, seminars, etc. Cellular networks are relatively new and are still developing. While employers can expect increased productivity due to employees being able to send and receive data at any time, one important drawback is the fact that the employees need to be in the range of coverage. This shouldn’t be a problem as long as the employee stays around a metropolitan area. ......

Once it is in the local exchange it is then sent to aggregating points in different cities and counties over the regional network. Then it is aggregated and transported over the long-haul network so that it reaches the launching point at the country shoreline where it is then sent over the ocean network to Japan. Once there, the email is sent back over the long-haul or regional network to the local exchange and then on to the individual receiving the email. This occurs using mostly fiber optics so the speeds at which all this takes is at the speed of light which is approximately 127,000 miler per second. understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network, being the access network. The access network is the network that connects the individual user or business with the telecommunications system. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange. The central office at the local exchange contains the switching equipment to direct your telephone, data , video, etc. to where it needs to go.

Cellular networks allow automatic and persuasive use of mobile phones for voice and data communication even though you usely use a cell phone to talk on it, the new cell phone killer app is data. Landlines phones use both voice and data networks. They work by transmitting voice and data signals by copper wire. Landlines refer to a phone that uses a solid medium telephone line such as a metal wire or fiber optic cable for transmission. In 2003 there was 1.263 billion main telephone lines worldwide. SMS/Text messaging known as short messages use a data network. SMS is a service component of phone, web, or mobile communication systems. It uses standardized communication protocols to allow fixed line or mobile phone devices to exchange messages using data application. Has an estimated 3.5 billion active users. Fax Machines use voice networks. With a fax line you plug into a fax terminal adapter, and then plugs into a network connection. They often share a phone extension and have a fax switch. You need to use a proper fax over IP protocol, such as T.38 to achieve consistent reliable faxing. Pagers are designed to receive the paging signals that are transmitted under control of the paging terminal. These paging signals are designed to carry pager-specific address information in order to alert an individual pager. Pagers use voice and data......

...Unit 1 Assignment 1 Cell Phones use voice and data communications. It uses the voice at a lot less these days because people rarely call one another anymore. Data is used for the applications which people use more of these days. So they use a mixture of both but mainly data. Also some phone now use Wi-Fi calling so people can use data networks to call people. Landlines use voice communication. Unlike data voice can work during a black-out because it doesn’t get its power from the same and everything in your house. It’s also a cheaper technology which also makes it cheaper. SMS/Text Messaging uses data. It’s part of the reason I said Cell Phones use both. And it can only be sent over 2G and above because 1G is voice only. Fax Machines use voice. It uses the same jack and RJ-11 like landlines do. It can be used on data but traditional fax use the voice network. The fax is sent it immediately gets digitized the put back in analog form once its sent. Pagers use data. It’s almost like SMS in the is send data (words over the networks). It’s an older technology. VOIP phone use data. It’s similar to Wi-Fi calling. It breaks up in to packets and is sent over the air waves. If you used a VOIP phone you could probably hear it sounding choppy that’s because those packets were dropped for some reason or another. Skype and face time also use data.

...computer and network device are connected to a single cable. This type of setup is not good for large networks for many reasons. Some reasons are difficulty in troubleshooting individual devices and the entire network, the network can fail if the cable is damaged, and the more devices on the network slows down the entire network. In contrary to larger networks, this set up is perfect for smaller networks, because it requires less cable length and setting up the actual network is easier as well. Ring This network is mostly used in schools and offices, where the networks are smaller. In this setup the devices are connected to each other going in a circle shape, so that each packet must go around the circle until it reaches its destination. Data flows only in one direction at high speeds between the workstations, therefore no requirement for a server needed.

GSM is used by AT&T, T-Mobile, and operates with a SIM card in conjuncture with the phone’s IMEI. Landline phones- A Landline phones uses voice networks. Transmits signals converted from audio data through physical media. It does this via copper wire or fiber optic cables. There are 2 basic types of landlines, a corded landline and cordless landline. Also todays landlines can transfer data through Modems to connect to the Internet. SMS / Text Messaging- Works on a voice network. SMS is a very small data transmission that does not use a lot of bandwidth. Also this works on the big three GSM, CDMA and TDMA network technologies to make it a universal service. SMS allows for text messages of 160 characters. In other languages the size is limited to 70 characters such as Chinese or Arabic. Fax Machines- Fax machines uses a voice and data network that is transmitted through bits of voice tone data. Fax machines make a distinctive sound when transmitting information.
