Cell Phones – Cellular phones are used for both voice and data communications. For example a person talking on a cellular phone uses voice communications and then gets sent back to the base station. Data technology is also used on smartphones which allow the user to browse the internet and download files.
Landline Phones – Landline phones typically only use voice communications. Some newer landline phones can use what is called a NCID (Network Caller ID) which uses data sent over a TCP connection.
SMS/Text Messaging – The SMS (Short Message Service) can be used in a variety of ways. Some examples include: cellular phones, GPRS systems, and web texting. SMS does not use any kind of voice technology and therefore is sent over data networks.
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. These types of pagers use a voice network to transmit a short audio message that the user can then retrieve.
VOIP Phones – VOIP (Voice over Internet Protocol) is a technology that can transmit audio messages over an internet protocol. The name voice would probably throw most people off, but since VOIP is transferred over an internet protocol it thereby uses data networks.
Skype/FaceTime – Both Skype and FaceTime utilizes video telephony and VOIP technologies. Originally video telephony was developed on image phones. These phones used still images that were sent over the POTS (Plain Old Telephone System) which used a voice telephony…...

...Unit 1 Assignment 1 1. Describe the role of software for computers: Computer software tells the hardware what to do. Without any software, the hardware would be worthless. Think of the software as a subject in school, and the hardware as you or your brain. Without any learning, you can't do anything. One you have learned some math, and then you are able to solve math problems. This learning is usually accomplished through downloads or CD's that are loaded into the computer. At the very basic level, computer software contains specific instructions for how to accomplish a specific task. These instructions tell the hardware exactly what to do, and how to do it 2. Identify the hardware associate with a computer: the physical components that make up a computer system. There are many different kinds of hardware that can be installed inside, and connected to the outside, of a computer. Here are some common individual computer hardware components that you'll often find inside a modern computer case: Motherboard, Central Processing Unit (CPU), Random Access Memory (RAM), Power Supply Video Card, Hard Drive (HDD), Solid-State Drive (SSD), Optical Drive (e.g. BD/DVD/CD drive) Card Reader (SD/SDHC, CF), etc. Here is some common hardware that you might find connected to the outside of a computer: Monitor, Keyboard, and Mouse 3.

...Unit 7. Assignment 1. Refraction, Reflection and Optics Refraction: The most common real life example used when discussing refraction is a straw in water. When a straw is placed in a glass of water and viewed from the side, it appears to be broken or bent. This is due to the difference in the refractive indices of air and water. Since water is denser than air, the straw appears to bend as the light it reflects is slowed by the density of the water. This phenomenon also makes submerged objects, such as fish look closer to the surface than they actually are. Another common example is a rainbow, where sunlight is refracted by raindrops. Sunlight consists of a mixture of different wavelengths, or colors, of light, with blue, for example, having a shorter wavelength than red. When this light passes through raindrops, the shorter wavelengths are bent more than the longer ones, splitting the light into its different colors. Reflection: Pretty much everything you see could be considered reflection. The fact we can see is due to light reflecting off of objects and into our eyes. A good example, I guess, is the moon. When it glows at night that is just light from the sun reflecting onto the Moon's surface, and bouncing back, giving it that glow. Degradation of signal strength in fiber-optic transmission. The main factors that affect this is number of connectors, splicing, Quality of Fiber / connectors, also not using an Attenuator according to the distance, or using dirty......

...Physical Networking Unit 1 Assignment 1 Cell phones – Cell phones use data networks to communicate over radio frequencies. The frequencies that they use are also shared with television, Bluetooth, and Wi-Fi. Landline phones – Landline phones use voice networks only because they do not need as much speed as anything else. Normal house phones use approximately 10 MB/s which is all that voice networks handle. SMS/Text messaging – Text messaging uses data networks because they can also be sending media like pictures and video. The other reason that I believe that text messaging uses data networking is because it is faster. Fax machines – Fax machines use voice because they only transmit exactly what is on the paper. It is not being transformed into little packets and sent over the internet to another place; it is just sent from one place to another through the phone line. Pagers – Pagers use the same as cell phones and that is data networks because it is wireless, and does not have to be plugged into anything. Pagers are not that common due to the cell phone industry growing swiftly. VOIP – VOIP as it says in the name of it uses a data network. It uses IP for talking so that the communication is more secure and not many people can tap in as easily as people can over regular phones.

...Unit 1 Exercise 1 Local Exchange When you send an email from New York to Japan, that email,is sent from your home to the local exchange point over the access network. Once it is in the local exchange it is then sent to aggregating points in different cities and counties over the regional network. Then it is aggregated and transported over the long-haul network so that it reaches the launching point at the country shoreline where it is then sent over the ocean network to Japan. Once there, the email is sent back over the long-haul or regional network to the local exchange and then on to the individual receiving the email. This occurs using mostly fiber optics so the speeds at which all this takes is at the speed of light which is approximately 127,000 miler per second. understand how to interface with the local exchange you must first understand the different networks that comprise it. The first network, being the access network. The access network is the network that connects the individual user or business with the telecommunications system. This is made up of a series of fiber-optic and copper cabling and passive and active equipment that connects you to the local exchange. The central office at the local exchange contains the switching equipment to direct your telephone, data , video, etc. to where it needs to go.

But of the way the LEDs are fabricated they are cheaper to make than lasers, they contain no hazardous material and last up to 10,000 hours. LEDs have a very small broad output which causes them to suffer chromatic dispersion in fiber. The bulbs create less heat during use which can lead to lower cooling costs and its green friendly, decreases amount of energy used by 5%. Laser Transmitter Laser transmitter have a much smaller and tighter light input and can be easily coupled to single mode fibers, this make the laser transmitter perfect for longer distances and high speed links. Laser has a high bandwidth capability some are used up to 10 GHz or 10 Gbps this makes Laser transmitters more expensive. Laser Transmitters have a narrow spectral output that suffers very little chromatic dispersion. Laser Transmitters avoid interference because the frequencies between the lasers have narrow beams that are less likely to have significant side lobes that could introduce interference. They could be applied when two or more buildings want to be connected to the same network or just to connect to or more networks. The transmitter takes an electron input and converts it to......

...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.

...wire-mapping test may be all that’s needed. Slightly more expensive devices do wire-map testing in addition to other basic functions, such as TDR length testing. A wire-map tester consists of a remote unit that you attach to the far end of a connection and the battery-operated, handheld main unit that displays the results. Typically, the tester displays various codes to describe the type of faults it finds. In some cases, you can purchase a tester with multiple remote units that are numbered, so that one person can test several connections without constantly traveling back and forth from one end of the connections to the other to move the remote unit. Continuity Testers - A continuity tester is an even simpler and less expensive device than a wire-map tester. It is designed to check a copper cable connection for basic installation problems, such as opens, shorts, and crossed pairs. These devices usually cannot detect more complicated twisted-pair wiring faults such as split pairs, but they are sufficient for basic cable testing, especially for coaxial cables, which have only two conductors that are not easily confused by the installer. Like a wire-map tester, a continuity tester consists of two separate units that you connect to each end of the cable to be tested. In many cases, the two units can snap together for storage and easy testing of patch cables. Fiber-Optic Test Sources - To measure the strength of an optical signal, a signal source must be at the other end of......
