Fax Machines – Fax machines contain analog modems. This type of modem technology uses the voice network technology. When the receiving end handles a fax connection it listens for a digital connection that has been converted from an analog signal using a voice network. Pagers – Pagers also known as beepers were primarily used over data networks by sending numerical short messages similar to the SMS service. Since the introduction of data pagers, voice pagers have also emerged.
3. ADSL doesn’t need to transfer data from digital to analogue and back again. 4. Connection from ADSL are always on, (allows quicker access to information on the internet) ADSL disadvantages. 1.

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.
There are different ways in which a modem converts digital signals into analog signals. Traditional modems (dial-up networks) are capable of converting data between the analog form used on telephone lines and the digital form used on computers. Broadband modems use more advanced signaling techniques because they are part of high-speed networks. Types of modems are Internal Modem, External Modem, Fax Modem, ADSL (Asymmetric Digital Subscriber Line) Modem, and ISDN (Integrated Services Digital

The fourth layer of the TCP/IP protocol defines how application interact with the third layer and include the highest levels of protocol like hyper text transfer protocol (HTTP), Telnet, domain naming system (DNS), simple mail transfer protocol (SMTP), and file transfer protocol (FTP) ("Four Layers Of TCP/IP Model, Comparison And Difference Between TCP/IP And OSI Models", 2014). Voice over Internet Protocol (VoIP). The VoIP allows Kudler Fine Foods to make phone calls over the broadband connection instead of standard dial-up connection. An advantage of the VoIP is that this allows Kudler Fine Foods to have additional phone numbers and service without having to pay for the phone service, however there are a few disadvantages to the VoIP phones. VoIP providers may not have directory assistance and may cost extra and some providers may not provide service during power outages ("Voice Over Internet Protocol (VoIP)", n. d.).
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
