• Cell Phones – Cell phones I would say uses both data and voice. You can use these devices to talk to other people via voice, and you can use it to access the internet via data services. Cell towers are essential for either of these functions to work.
• Landline Phones - Landline phones originally were voice only. Created to carry audio from human beings. With the invention of modems, and then to IDNS and now DSL, it is also used as data as well.
• SMS / Text Messaging – SMS / Text messaging uses Data services. These services allow you to send and receive blocks of characters (ie letters / numbers) between devices. There are no vocal communication done between these devices.
• Fax Machines – Fax Machines use data services. It takes a digital print of a document and turns them into packets of data to be sent to a receiving fax machine that then takes those packets of data and translates them into a printed document.
• Pagers – A pager is a device that uses data services. It would take an incoming call by its tone and transfer that data into a readable digital message. This way the receiving person can then use that message to call back a person at the given number on the device.
• VOIP (voice over IP) Phones – VOIP like Vonage uses Data services. One might think that voice services would be used seeing you are making a call, but it’s all done on a digital level. It takes your voice, transforms it into data that is then sent out and transformed back into voice at the receiving end. It bypasses the local phone companies and lets us use the internet to make calls.
• Skype / Facetime – Skype is a data service. It uses data to use the internet like VOIP to communicate but on a more elaborate platform. These applications not just use audio but also uses visual when...

...The data for this study were collected in the form of semi-structured interviews from 6 volunteer 5th-grade chemistry student teachers. The data was analyzed based on an inductive analytical approach. The results indicated that different types of feedback based on self-efficacy belief sources directly affected the student teachers' self-efficacy beliefs and teaching performance. It may be concluded that different types of feedback provided key paths for student teachers to better understand their own developing teaching performance and that of other teachers. I agree with Akkuzu’s with the role of different types of feedback in the reciprocal interaction of teaching performance and self-efficacy belief. Because, due to the data that was analyzed based on an inductive analytical approach. Someone or scientist cannot just think and jump into conclusion without carryout his/her experiment to see what the result is. Therefore, I agree with Akkuzu and the data analyses.

Improving User Authentication on Mobile Devices:

...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....

Coke or Pepsi, Financial Analysis

...Coke or Pepsi, what would you choose? xxxxxx XACC/280 xxxxxx teacher name Everyone in the civilized world recognizes two companies as kings of the soda pop, Pepsi-Cola and Coca-Cola. These two companies have battled for over one hundred years to be top dog in the beverage business. In 2005, Coca-Cola (Coke) led the race by just over 7% in net income over Pepsi-Co (Pepsi). This essay will compare these two beverage giants side by side and analyze the financial statements of both as well as making suggestions about ways the each company may be able to improve their earnings. Pepsi-Cola was born in North Carolina, in 1898, as the invention of a pharmacist named Caleb Bradham. He put together various combinations of juices, syrups, and spices to try to come up with a new drink to serve to his customers at the soda fountain in his pharmacy. His drink, originally called “Brad’s drink” was soon renamed Pepsi-Cola (using a combination of the names of two of the ingredients Pepsin and Kola nuts). The drink was incredibly successful and soon took off beyond Bradham’s wildest expectations. In 1902, the Pepsi-Cola company was officially formed and the brand was patented. The beverage quickly moved from a soda fountain product to a bottled beverage (PepsiCo, Inc, 2010). The second half of this duo is Coca-Cola. Coca-Cola was invented in 1886, twelve years before Pepsi. It was created by Doctor John Pemberton, also a......
