Landline phones also use both of these communications: voice and data. Voice is transferred through the wires as data packets. Key pulses send tones; meaning data is transmitted.
SMS/Text Messaging use data communication. Short Messaging Service (SMS) is a way of sending/receiving messages containing a maximum of 160 character per message over mobile networks. These messages are broken into binary and sent as wireless data packets over mobile packets.
Fax Machines use data communications similar to VOIP (Voice over Internet Protocol). Fax machines plug into a Fax Terminal Adapter (FTA) before connecting to the network via: switch, router, modem, and etcetera. Fax machines scan documents, transforming the scanned image into data packets, then transmits the packets to the receiving party.
Pagers use data communication to receive incoming calls. Pagers receive the packets and decode them to display the incoming caller’s numbers. Similar to cell phones, pagers notify individual of incoming calls by tone.
VOIP (Voice over IP) phones use digital technology to make phone calls over the internet rather than phone lines, meaning they use data communications. VOIP phones transform voice communications into data packets before transmitting them across the internet.
Skype/Facetime can only be used through data communications. Skype and Facetime are used for VOIP and Video Conference Calling. In order for this to work, video and voice is turned into packets and transmitted as data to the receiving party; then is decoded and displayed/heard on the receiving side.
