...Unit 1 Assignment 1 voice vs data Dominic Hennen Cell phones use a both voice and data networks you can speak which is going out over the voice network. You will also be using the data network for all your internet surfing as well as your text messages and pictures been sent as well, Landline phones use a voice network for talking to other people over the network on the older internet before high-speed internet they also sent data but that technology has fallen to the wayside with the takeover of high speed internet. SMS/text messaging are using the data network so you can send pictures and just text to another person much in the way a email will work just text no voice. Fax Machines send data by compressing the image that was scanned and sending it out over the line the fax receives and sends digital tones and this is how the communicate with one another. Pagers are a telecommunication device but are data networks there are no voice being transmitted over the proses. Some pagers will send a voice recording instead of a call back number… VoIP is a data network allowing you to talk to other individuals on the phone but it sends your voice over a high-speed internet connection and will communicate with a voice only network both side of the conversation doesn’t have to be VoIP.

...Unit 1 Assignment 1. Voice vs. Data Cell phones use both voice and data networks. Both of these networks can use the same antenna. 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 networks...

...Samuel Johnson NT1310 Unit 1. Assignment 1 September 17, 2015 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...

...Cell Phones- Use a combination of Voice and Data network to communicate with the service provider. Depending on your service provider you will be using CDMA or GSM Technology which operates on the 850Mhz and 1900Mhz. CDMA is used by Sprint, Verizon Cellular, and U.S. Cellular. 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. With a photo sensor, a fax machine looks for white areas sending one tone. If it there were black areas it would send a different tone. Pagers- Are used on a voice network.

Landline phones uses the same as cell phones SMS/Text messaging uses data networks because it takes and saves an image of text and sends it over to the other end. Fax Machine uses data networks because a file is saved and sent over to the fax machine to be printed out. Pagers uses data networks because it is recorded and saved while being transfer over to the pager. VOIP (voice over IP) phones uses voice data networks. Skype/Facetime uses voice data networks because of live video streaming. Unit 1 Exercise 1, Local Exchange Any movements and sounds on one end is recorded and sent as data through demarc live-tie, to the access networks. Then from access network it would go through metro network (city to city) and regional networks (county to county). From there it travels to long haul (state to state). Then to ocean networks (country to country) if players are out of the country gamers. After all that transfers, it back tracks to the other end of the receiver who is playing the game. Unit 1 Lab 1. Data on Fixed Line vs Cellular Debate Data Speed depends on the environment.

...Improving user authentication on mobile devices: A Touchscreen Graphical Password Summary By: Quaniesha Hillian December 12, 2013 Abstract We analyze three biometric verification modalities – voice, face and motion – and in addition secret word passage, on a portable gadget, to investigate the relative requests on client time, exertion, blunder and errand interruption. Our research center study furnished perceptions of client movements, techniques, and responses to the validation strategies. Face and voice biometrics conditions were speedier than watchword passage. Talking a Pin was the speediest for biometric specimen entrance, yet fleeting memory review was better in the face check condition. None of the confirmation conditions were recognized exceptionally usable. In conditions that consolidated two biometric entrance routines, the opportunity to get the biometric examples was shorter than if obtained independently yet they were extremely disliked and had high memory assignment blunder rates. These quantitative effects exhibit cognitive and engine contrasts between biometric verification modalities, and brief strategy choices in selecting confirmation. Typing text passwords is challenging when using touchscreens on mobile devices and this is becoming more problematic as mobile usage increases. They designed a new graphical password scheme called Touchscreen Multi-layered Drawing specifically for use with touchscreens. They conducted an exploratory...
