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. VOIP Phones use digital technology to make phone calls on the internet rather than through phone lines. Analog voice calls are converted into packets of data. The packets travel like any other type of data. Using VOIP service, you can call landline or cell phone. VOIP phone use voice over IP technology.

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. They conducted an exploratory...
